To install flake floor coating, prepare a sound, clean concrete surface, apply a compatible primer and basecoat, broadcast decorative flakes into the wet basecoat, remove loose flakes after curing, and seal the floor with the specified clear topcoat. The exact products, mixing ratios, coverage, recoat windows, and cure times depend on the coating system, so follow the current technical data sheets (TDS) for every component. For a dependable result, plan the work around substrate condition, moisture, temperature, ventilation, and the time the area can remain out of service.
Begin by identifying the substrate, its age and condition, previous coatings, cracks, joints, and likely sources of moisture. Remove oil, grease, curing compounds, dust, and other contaminants using methods suitable for the floor and coating system. If an existing coating is present, determine whether it is firmly bonded and compatible; do not assume that a new coating will adhere to it.
Mechanical preparation, such as diamond grinding or shot blasting, is commonly used to create a clean, profiled concrete surface. The required profile depends on the coating manufacturer’s instructions and the condition of the slab. Repair cracks and surface defects with compatible materials, while treating moving joints according to the project design rather than simply covering them.
Check moisture using a test method accepted by the coating manufacturer, and record the result before installation. Excess moisture or vapor transmission can contribute to adhesion problems, blistering, or other coating defects, but acceptable limits vary by product and test method. If the slab is damp or the source of moisture is unclear, pause and seek technical guidance before coating.
Typical equipment includes surface-preparation tools, an industrial vacuum, mixing buckets, a low-speed mixer, a roller frame, brushes, and a suitable squeegee or roller for distributing the basecoat. Prepare flakes in manageable batches and keep the selected topcoat, application tools, and waste containers close to the work area. Wear personal protective equipment specified by the product safety data sheets, and provide ventilation appropriate to the products and site.
Remove weak concrete, laitance, old material that is not firmly bonded, and contaminants using an appropriate mechanical preparation method. Vacuum thoroughly so that dust does not remain in pores, corners, or along edges. After cleaning, inspect the surface again under good lighting and correct any missed contamination or unstable areas before applying product.
Fill suitable cracks, pits, and spalls with a compatible repair compound, then allow the repair to cure as directed. Keep control joints and movement joints visible or detail them according to the project specification. Before coating, confirm that air and substrate temperatures, humidity, and moisture conditions fall within the limits stated in the product documentation.
Mix the primer components in the specified ratio and quantity, using clean tools and the mixing method stated by the manufacturer. Avoid changing the ratio to make a product spread more easily, because this may affect curing or performance. Apply a uniform coat without leaving puddles, dry patches, or uncoated edges, and observe the specified recoat window before proceeding.
Prepare only the amount of basecoat that the crew can place within its working time. Spread it evenly across the floor, maintaining a wet edge and working toward an exit so installers do not become trapped behind the coated area. Basecoat color influences the final appearance, especially where flake coverage is intentionally partial, so confirm the color and coverage plan before the full installation.
While the basecoat is wet, broadcast flakes by hand or with suitable equipment, using a consistent method across each section. For a full-broadcast finish, installers typically continue until the wet surface is covered; the project specification and desired texture determine the actual amount. Avoid throwing flakes unevenly or allowing the basecoat to skin over before application, as either can create inconsistent appearance or bonding.

Keep the area protected while the basecoat cures for the period specified in its TDS. Once it is ready for the next step, remove loose flakes using a scraper, broom, and vacuum as appropriate, then inspect the surface for bare areas, sharp projections, or contamination. Do not begin scraping or topcoating based only on a general schedule; temperature and product chemistry can change the working and cure window.
Mix and apply the compatible clear coat according to its instructions, maintaining even coverage and avoiding pools or missed areas. The topcoat contributes to the final surface appearance and affects cleanability and wear characteristics, so select it for the intended traffic, cleaning routine, and exposure conditions. Some projects specify more than one clear coat; follow the system specification rather than adding coats without confirming compatibility and recoat requirements.
Restrict foot traffic, equipment, water, and cleaning until the product documentation permits each activity. A coating may feel dry before it has reached the cure stage required for heavier use, so communicate reopening times clearly to the site team. Keep temporary coverings from touching or trapping moisture against the new surface unless the manufacturer confirms that the protection method is suitable.
Choose between partial and full flake coverage based on the design, desired visual effect, and specified finish. Flake size, blend, broadcast density, and topcoat build all influence the final appearance and texture. Request or prepare a sample panel when stakeholders need to approve color, flake distribution, or the feel of the finished surface before work begins.
Installation windows are product-specific. As a planning example only, some coating systems may require ambient and substrate temperatures within a range such as 10–30°C, while others set different limits; the product TDS takes precedence. Likewise, a stated recoat or return-to-service time must be checked against actual site conditions and the manufacturer’s guidance.
Do not choose a coating thickness based on appearance alone. A system might be specified at approximately 1–2 mm overall, but this is an illustrative range, not a universal requirement; substrate condition, traffic, product design, and project specification determine the appropriate build. Confirm coverage rates and expected thickness with the supplier before estimating material quantities.
Divide large floors into sections that installers can coat and broadcast within the product’s working time. Assign clear roles for mixing, spreading, broadcasting, and monitoring the wet edge so that application remains consistent. Before work begins, agree on a batch plan, material staging, access route, and contingency for delays.
Record product names and batch numbers, mixing ratios, environmental conditions, moisture-test results, and application times. This information helps the project team review installation conditions if questions arise later. For a commercial project, also confirm the expected traffic, cleaning chemicals, slip-resistance requirements, and any local project specifications with the responsible designer or facility team.
As a flake floor coating manufacturer and supplier, Vanlei can help B2B buyers discuss decorative flake options, system components, project requirements, and product documentation. Share the substrate type, approximate floor area, intended use, location conditions, preferred appearance, and project schedule when requesting a recommendation. Our team can use those details to clarify suitable product options and the information needed for a project-specific installation plan.
To install flake floor coating successfully, prepare and assess the concrete, use compatible system components, apply flakes at the correct stage, remove loose material, and protect the finished floor through the required cure period. The most important next steps are to review the product TDS, verify substrate moisture and site conditions, and confirm the desired flake coverage and topcoat with the project team.
