For companies that hire a contractor, the hardest part is often sign-off, because gloss and evenness can only be judged fairly when both sides agree on a sample area and acceptance criteria before work starts.<\/p>\n<p>BPG Group is ISO 9001:2015 certified and received The Best of Vietnam 2024 award. Each cleaning project is carried out item by item as agreed, with photo reports of the results and an acceptance record signed by both parties.<\/p>\n<h2>How concrete floor polishing differs from regular floor cleaning<\/h2>\n<p>Concrete floor polishing changes the structure of the top layer, while regular floor cleaning only removes dirt sitting on the surface. Grinding strips away the weak cement paste and coarse particles to expose denser concrete underneath, and the densifier then fills the tiny pores, so the floor resists oil and dust far better than raw concrete.<\/p>\n<p>For factories and warehouses, this difference brings three practical benefits:<\/p>\n<ul>\n<li>A polished concrete floor sheds less dust when forklifts and trolleys pass, so less dust settles on goods and equipment near the aisles.<\/li>\n<li>Closed pores make daily scrubbing and oil cleanup faster and use less cleaning chemical than on raw concrete.<\/li>\n<li>The floor reflects more light, so production and storage areas look brighter under the same lighting.<\/li>\n<\/ul>\n<p>Because polishing restores the surface rather than cleaning it, it should be planned as a separate project, not bundled into a routine cleaning contract. Choosing the right gloss level at the start decides most of the work time and cost of that project.<\/p>\n<h2>Three gloss levels and where each one fits<\/h2>\n<p>Polished concrete is usually grouped into three finish levels based on how much it reflects: matte, semi-gloss and high-gloss. A higher level needs more fine grinding and polishing passes, so it helps to decide what each area will be used for before asking for a quote.<\/p>\n<p>The image below shows a factory floor after grinding and polishing, with a clear reflection under natural light.<\/p>\n<p><img alt=\"BPG technician running a concrete floor polishing machine in a warehouse in Vietnam\" src=\"https:\/\/bpggroup.vn\/wp-content\/uploads\/2026\/10\/concrete-floor-polishing-vietnam-gloss-levels.jpg\" width=\"1448\" height=\"1086\" loading=\"lazy\" decoding=\"async\" \/><\/p>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"background-color: #1a6b6b !important; color: #ffffff !important; font-weight: bold; padding: 12px; border: 1px solid #e0e0e0; width: 22%; text-align: left; vertical-align: top;\">Finish level<\/td>\n<td style=\"background-color: #1a6b6b !important; color: #ffffff !important; font-weight: bold; padding: 12px; border: 1px solid #e0e0e0; width: 38%; text-align: left; vertical-align: top;\">Surface<\/td>\n<td style=\"background-color: #1a6b6b !important; color: #ffffff !important; font-weight: bold; padding: 12px; border: 1px solid #e0e0e0; width: 40%; text-align: left; vertical-align: top;\">Best suited to<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Matte<\/td>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Flat, low reflection, keeps more texture for better slip resistance.<\/td>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Production areas with heavy forklifts, zones that are often wet or oily.<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #eaf4f4 !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Semi-gloss<\/td>\n<td style=\"background-color: #eaf4f4 !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Moderate reflection, a balance between appearance and wheel grip.<\/td>\n<td style=\"background-color: #eaf4f4 !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Warehouses, packing areas, office building car parks.<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">High-gloss<\/td>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Mirror-like reflection, needs many extra fine grinding and polishing passes.<\/td>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Showrooms, factory office lobbies, product display areas.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>High-gloss is not recommended in workshops with constant forklift traffic, because a very smooth surface raises the risk of wheel slip under heavy loads or when the floor is wet. Within one plant, you can choose matte for production and semi-gloss or high-gloss for the office lobby, as long as the boundaries are marked on the survey drawing.<\/p>\n<h2>The 6-step concrete floor polishing process<\/h2>\n<p>A proper concrete floor polishing job runs through six steps in sequence: surface survey and repair, coarse grinding, intermediate grinding, densifier application, fine grinding and polishing, then sealing and sign-off. Skipping a grit in the middle leaves scratches from the previous step, and the floor will not reach an even gloss even if the later steps are done right.<\/p>\n<p>The image below summarises the six steps in the same order as the list.<\/p>\n<p><img alt=\"6-step concrete floor polishing process, from surface survey to handover\" src=\"https:\/\/bpggroup.vn\/wp-content\/uploads\/2026\/10\/concrete-floor-polishing-process-6-steps.jpg\" width=\"1200\" height=\"1200\" loading=\"lazy\" decoding=\"async\" \/><\/p>\n<ul>\n<li><strong>Survey and surface repair:<\/strong> the crew checks hardness, flatness and defects such as cracks, pinholes, level differences or old coatings, and agrees the repair approach with you before grinding.<\/li>\n<li><strong>Coarse grinding:<\/strong> the grinder runs metal-bond diamond tooling to remove weak paste, deep stains and old coatings, bringing the surface back to sound concrete.<\/li>\n<li><strong>Intermediate grinding:<\/strong> the crew moves to finer grits to remove the scratches from coarse grinding and flatten the whole floor evenly.<\/li>\n<li><strong>Densifier application:<\/strong> a silicate densifier (lithium, sodium or potassium) is sprayed once the pores are open, reacting with the concrete to harden it and reduce surface dust.<\/li>\n<li><strong>Fine grinding and polishing:<\/strong> resin-bond pads in fine grits are run in several passes until the floor reaches the gloss level chosen at the survey.<\/li>\n<li><strong>Sealing, cleanup and sign-off:<\/strong> a protective sealer that resists oil goes on last, grinding dust is vacuumed up, and both sides check the gloss against the agreed sample.<\/li>\n<\/ul>\n<div style=\"background-color: #eaf4f4; padding: 16px; border-left: 4px solid #1a6b6b;\">\n<strong>Technical note:<\/strong> A silicate densifier penetrates and reacts inside the concrete, unlike epoxy paint, which only forms a film on top. That is why a polished concrete floor does not peel off in patches under long-term forklift traffic, although its gloss still needs to be kept up with the right cleaning chemicals.\n<\/div>\n<p>These six steps apply to both new and old floors, the only difference being how much work goes into the survey and coarse grinding. Two groups of materials decide the quality of the whole process, chemicals and machines, so it is worth asking the contractor which ones they use.<\/p>\n<h2>Densifiers, sealers and polishing machines<\/h2>\n<p>Chemicals and machines are the two factors that decide the hardness, gloss and durability of a polished concrete floor. You do not need to pick each product yourself, but you should ask the contractor to state the product types in the quote and to provide safety data sheets (SDS) before anything is brought into the factory.<\/p>\n<h3>Densifier and protective sealer<\/h3>\n<p>Concrete polishing chemicals fall into two groups used at different stages. The first is a silicate densifier, which soaks into the concrete midway through the process to harden the surface. The second is the protective sealer applied at the end, which helps the floor resist oil and water and makes it easier to clean in daily use.<\/p>\n<h3>Grinders and diamond polishing pads<\/h3>\n<p>A dedicated concrete polishing machine is usually a multi-head planetary grinder, which differs from a cleaning scrubber in down pressure, speed and the way tooling is mounted. Concrete polishing pads are graded by grit, from metal-bond diamonds for coarse grinding to resin-bond pads for fine polishing. The grinder needs either continuous water feed or a compatible industrial vacuum to control grinding dust throughout the job.<\/p>\n<p>Because grinders and multi-grit tooling are expensive, buying them for a one-off job rarely makes more sense than hiring a specialist crew. Alongside materials, dust control is a requirement to set from day one when grinding inside a working factory.<\/p>\n<h2>Dust control when grinding concrete in a working factory<\/h2>\n<p>Grinding concrete produces fine dust that contains silica, so the grinder must run with continuous water feed or a dust collection system as recommended by the manufacturer. Table 1 of <a href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1926\/1926.1153\" target=\"_blank\" rel=\"noopener\">OSHA 1926.1153 on respirable crystalline silica<\/a> in the United States lists exactly these two controls for walk-behind floor grinders and requires the equipment to be operated according to the manufacturer&#8217;s instructions to minimise dust.<\/p>\n<p>If the factory keeps running during the work, agree these points with the contractor in advance:<\/p>\n<ul>\n<li>The grinding area is fenced off and signposted so workers and forklifts stay out while the crew is working.<\/li>\n<li>Work is scheduled zone by zone, preferably during breaks, weekends or shutdown days, so production lines are not interrupted.<\/li>\n<li>Goods, equipment and electrical cabinets near the grinding area are covered before coarse grinding starts.<\/li>\n<li>Slurry from wet grinding is collected and treated, not discharged straight into the plant&#8217;s stormwater drains.<\/li>\n<\/ul>\n<p>These requirements are also a good way to judge whether a contractor is used to working inside factories. For floors that have been in use for years, or plain cement screeds, the next question is usually whether the surface can be polished at all.<\/p>\n<h2>Can plain cement screeds and old concrete floors be polished?<\/h2>\n<p>Both plain cement screeds and old concrete floors can be polished, but the gloss and durability you get depend on how dense the top layer is. A polished cement screed usually reaches a lower gloss and shows more pinholes than high-strength concrete, because the cement layer is thin and weaker under repeated grinding.<\/p>\n<p>On old concrete floors, the crew usually has to deal with three issues first:<\/p>\n<ul>\n<li>Oil that has soaked in for years needs more degreasing and coarse grinding, because leftover oil stops the densifier from penetrating evenly.<\/li>\n<li>Cracks, pinholes and broken joint edges need to be filled first, otherwise they become more visible once the floor is glossy.<\/li>\n<li>Old epoxy paint or line markings need to be stripped completely, because coatings clog the tooling and leave the grind uneven.<\/li>\n<\/ul>\n<p>Since the amount of preparation varies from floor to floor, a site survey is a must before quoting for an old floor. The way BPG organises a polishing project below shows how the survey links to the quote and the sign-off.<\/p>\n<h2>How BPG Group runs concrete floor polishing projects in Vietnam<\/h2>\n<p>BPG Group handles concrete floor polishing as a one-off project, moving from site survey and itemised quote to the works, photo reports and a signed acceptance record. This gives you clear evidence at sign-off, rather than a quick visual handover as the crew packs up.<\/p>\n<ul>\n<li>You send basic information: address, floor area, type of factory or warehouse and the current condition of the floor.<\/li>\n<li>BPG surveys the site to identify floor defects and the right gloss level for each area, and the survey is free of charge.<\/li>\n<li>BPG sends a quote broken down by item, including labour, machines and specialist chemicals.<\/li>\n<li>After the contract is signed, the crew completes each agreed item in turn.<\/li>\n<li>On completion, BPG sends photo reports of the result for each item.<\/li>\n<li>Both sides inspect the floor and sign the acceptance record.<\/li>\n<\/ul>\n<p>To make sign-off about more than impressions, you can use the checklist below. It sums up the points that facility managers often see missed when a polished floor is handed over.<\/p>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"background-color: #1a6b6b !important; color: #ffffff !important; font-weight: bold; padding: 12px; border: 1px solid #e0e0e0; width: 30%; text-align: left; vertical-align: top;\">What to check<\/td>\n<td style=\"background-color: #1a6b6b !important; color: #ffffff !important; font-weight: bold; padding: 12px; border: 1px solid #e0e0e0; width: 70%; text-align: left; vertical-align: top;\">How to check it at sign-off<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Even gloss<\/td>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Look at the floor under low-angle light from a doorway or a torch and compare it with the sample area agreed at the survey.<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #eaf4f4 !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Swirl marks<\/td>\n<td style=\"background-color: #eaf4f4 !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Look for circular scratches left by a skipped grit, usually easiest to see in the middle of main aisles.<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Wall and column edges<\/td>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Check the strip along walls, columns and racking legs, where the large grinder cannot reach and hand tools are used.<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #eaf4f4 !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Joints and repaired cracks<\/td>\n<td style=\"background-color: #eaf4f4 !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Check that joint edges and filled areas are flush with the floor, with no dips or loose filler.<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Post-work cleanup<\/td>\n<td style=\"background-color: #ffffff !important; padding: 12px; border: 1px solid #e0e0e0; text-align: left; vertical-align: top;\">Check for grinding dust on racks, machines, window sills and drains around the ground area.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Photo reports for each item, together with this checklist, give the person in charge a complete record to submit for payment approval. Once the method and sign-off are clear, the next question is usually what drives the cost of a polishing project.<\/p>\n<h2>What drives a concrete floor polishing quote<\/h2>\n<p>BPG prepares concrete floor polishing quotes after the site survey, based on floor area, surface condition, the gloss level required and the actual working conditions on site. We do not apply one fixed rate to every floor, because a new slab and an old oil-soaked floor of the same size need very different amounts of grinding. For the price of your project, please contact us for a quote.<\/p>\n<p>The main factors that affect the quote are:<\/p>\n<ul>\n<li><strong>Floor condition:<\/strong> many cracks, pinholes, deep oil or old coatings mean more repair and coarse grinding.<\/li>\n<li><strong>Gloss level:<\/strong> the higher the gloss, the more fine grinding and polishing passes are needed.<\/li>\n<li><strong>Area and layout:<\/strong> small areas can be quoted as a lump sum instead of per square metre, while floors with many columns and fixed racks need more hand-tool work.<\/li>\n<li><strong>Working hours:<\/strong> work outside office hours, at night or on public holidays to avoid disrupting production may carry a labour surcharge, shown clearly in the quote.<\/li>\n<li><strong>Site location:<\/strong> remote sites may carry extra costs for transporting staff and equipment, also shown clearly in the quote.<\/li>\n<\/ul>\n<p>To compare quotes from different contractors on the same floor, ask each one to list repairs, grinding, densifier, sealer and out-of-hours surcharges as separate lines. More detailed points for assessing a contractor are covered in our guide to <a href=\"https:\/\/bpggroup.vn\/en\/criteria-for-choosing-industrial-cleaning-company\/\">choosing an industrial cleaning company<\/a>, which applies to floor polishing as well.<\/p>\n<h2>Keeping a polished concrete floor in good condition<\/h2>\n<p>A polished concrete floor still needs daily cleaning with a neutral cleaner and the right tools to keep its gloss. In most cases where a floor deteriorates quickly, the cause is not the installation but the wrong cleaning habits in the first months of use.<\/p>\n<ul>\n<li>Strong acidic or alkaline cleaners eat into the protective sealer, and the floor slowly turns dull.<\/li>\n<li>Sand, metal chips and debris left on forklift aisles act like sandpaper every time a wheel rolls over them.<\/li>\n<li>Oil and chemical spills left for hours have time to soak into spots where the sealer has worn thin.<\/li>\n<li>Pads that are too aggressive during periodic scrubbing gradually remove the gloss achieved in the fine polishing stage.<\/li>\n<\/ul>\n<p>If your factory also needs routine floor care after polishing, our <a href=\"https:\/\/bpggroup.vn\/en\/services\/industrial-cleaning-services\/\">industrial cleaning services<\/a> cover scheduled deep cleaning of floors, walls and high areas in factories and warehouses.<\/p>\n<h2>Frequently asked questions about concrete floor polishing<\/h2>\n<h3>How long does concrete floor polishing take?<\/h3>\n<p>The time needed depends on floor area, surface condition and the gloss level chosen. A new floor with few defects needs fewer coarse grinding passes, while an old floor with many cracks or deep oil needs extra preparation before grinding. BPG sets the schedule for each area after the site survey.<\/p>\n<h3>Can a newly poured concrete floor be polished straight away?<\/h3>\n<p>No, it should not be polished right after pouring. Concrete needs time to cure and reach its design strength, usually measured at 28 days, before it can take multi-stage grinding. The exact start date should be agreed with the design engineer and follow the densifier manufacturer&#8217;s guidance.<\/p>\n<h3>Can concrete floor polishing replace epoxy paint?<\/h3>\n<p>Polished concrete and epoxy paint are two different solutions for different needs. Polished concrete suits areas with heavy forklift traffic that need a hard-wearing surface that will not peel, while epoxy is better when you need colour-coded zones or a sealed coating for areas with special hygiene requirements. It is best to choose by the function of each area rather than apply one solution to the whole plant.<\/p>\n<h3>Can the floor be polished while the factory is still running?<\/h3>\n<p>Yes, if the work area is split into smaller zones, fenced off and scheduled around breaks or shutdown days. The grinder needs water feed or dust extraction to stop dust spreading into production areas. Work outside office hours, at night or on public holidays may carry a labour surcharge, shown clearly in the quote.<\/p>\n<h3>How should a polished concrete floor be maintained?<\/h3>\n<p>A polished concrete floor should be swept, mopped or scrubbed with a neutral cleaner at a frequency that matches the traffic in each area. Oil and chemical spills should be wiped up straight away so they do not soak in. When the gloss drops noticeably on main aisles, you can plan a local re-polish instead of regrinding the whole floor.<\/p>\n<h2>Request a site survey for concrete floor polishing<\/h2>\n<p>If you need concrete floor polishing for a factory, warehouse or factory office lobby in Ho Chi Minh City or southern Vietnam, send us the floor area, current condition and the hours when work is possible via hotline 0707 43 9899 or email info@bpggroup.vn.
