First Coat: Primer Application
Proper primer application ensures strong adhesion between your substrate and the subsequent epoxy or polyurethane materials. Attention to surface preparation, correct mixing ratios, and thorough coverage form the foundation for long-lasting, ultra-wear-resistant floors.
Objective
The primary objective of primer application is to seal the concrete slab and create an optimal bond for subsequent coats. This layer helps to penetrate micro-pores in the substrate, reducing air release, enhancing adhesion, and minimizing bubbles in later layers.
A well-applied primer also plays a crucial role in moisture control. By using appropriate moisture mitigation systems, you can prevent future coating failures caused by high moisture vapor transmission rates. Verification of the surface profile ensures that the primer can properly adhere, contributing to the durability of the flooring system.
Materials & Mixing Ratio
Materials you will need:
- Epoxy primer (two-component system)
- Mixing bucket
- Low-speed drill with mixing blade
- Measuring containers
- Clean roller or squeegee
The recommended mixing ratio for epoxy primers usually ranges from 2:1 to 4:1 (resin) by volume, depending on the manufacturer’s specifications. Always follow the product data sheet for precise ratios. Incorrect ratios or poor mixing can impair curing and reduce adhesion.
Mix for at least 2–3 minutes, scraping sides and bottom frequently to ensure a uniform, streak-free mixture. Avoid whipping air into the material, as this can lead to bubbles. Only mix quantities you can apply within the working time (pot life) indicated by the supplier.
Procedure
- Surface Preparation:
- Mechanically prepare the concrete using diamond grinding equipment or shot blasting machines to achieve the correct Concrete Surface Profile (CSP) level, most often CSP 2–3.
- Remove dust, oil, grease, and loose material. Test for moisture using calcium chloride tests or in-situ relative humidity testing.
- If moisture exceeds product limits, install a suitable moisture control system.
- Primer Application:
- Pour mixed primer directly onto the floor in ribbons.
- Spread evenly using a squeegee, then back-roll with a lint-free roller to ensure complete coverage.
- Work methodically to avoid puddles or missed spots.
The floor should be uniform and slightly tacky after primer application. Allow the primer to cure fully according to product guidelines before overcoating to achieve the best adhesion. If the primer sits for too long before recoating, sanding may be required to restore the bond.
Second Coat: Intermediate Mortar Layer
The intermediate mortar layer is critical for mechanical strength, wear resistance, and longevity. Proper material selection, accurate mixing, and careful application are necessary for optimal results.
Objective
The main goal of the intermediate mortar layer is to enhance the overall durability and impact resistance of the floor. This layer bridges the gap between the primer coat and topcoat, providing a solid base for heavy loads and frequent traffic.
You will achieve improved abrasion and ultra-wear resistance by embedding broadcast media, such as quartz sand, into the epoxy matrix. This process also increases slip resistance and maintains the self-leveling qualities essential for industrial and commercial environments.
Properly applied, the mortar layer prevents delamination and prolongs floor life, especially in areas where forklifts, carts, and heavy machinery are in use.
Materials & Mixing Ratio
You will need two main components for the intermediate mortar: Intermediate Mortar Layer Epoxy and clean, dried quartz sand. The standard mixing ratio is typically 1 part epoxy resin to 3-5 parts quartz sand by weight, though this may vary by manufacturer.
Use a mechanical mixer for even blending. The quartz sand particle size should be 0.3-0.8 mm for optimal strength and finish. Always use a high-purity sand to prevent contamination.
Additives such as thixotropic agents may be considered for vertical surfaces, though most quartz sand epoxy flooring applications are horizontal. Use only manufacturer-approved materials to ensure chemical compatibility and performance.
Procedure
Begin by pouring the mixed epoxy and quartz sand onto the primed substrate. Distribute the mixture evenly using a notched trowel or squeegee. Aim for a uniform layer between 2-4 mm thick, depending on specified project requirements.
After spreading, broadcast additional quartz sand evenly over the wet epoxy until the surface is completely covered and no wet spots remain. This is essential for creating a strong mechanical lock and enhancing slip resistance.
Allow the layer to cure fully (typically 8-12 hours at 25°C) before removing excess, loose sand. Make sure no aggregates are left unsecured, as this may affect adhesion for the subsequent topcoat application.
Third Coat: Intermediate Putty Layer
The intermediate putty layer provides an essential base that strengthens surface integrity and addresses level differences or minor substrate defects. Proper application and consistent mixing are key to achieving optimal results for long-lasting performance.
Objective
The primary goal of the Epoxy Putty Layer is to smooth irregularities and fill surface imperfections. This coat acts as a transition between the primer and self-leveling layers. It levels minor cracks, holes, or abrasions left in the concrete substrate.
Creating a consistent, flat surface is necessary for the performance of both the self-leveling and final finish coats. The correct application ensures strong adhesion, prevents bubbles, and avoids future coating failures. For new or heavily damaged floors, applying the putty layer improves foot and machinery traffic durability.
Materials & Mixing Ratio
You need a high-quality, two-component epoxy putty formulated for flooring applications. The components typically include:
- Epoxy resin (A)
- Special hardener (B)
- Filler additives (such as quartz powder or silica sand)
A typical mixing ratio is A:B = 4:1 by weight. Add filler at around *0.5 to 1.0 parts by weight* depending on floor condition and desired consistency. Use a clean container and a low-speed electric mixer (300-500 rpm) for thorough blending.
Tip: Only prepare as much as you can apply within the pot life (usually 30–40 minutes at 25°C). Improper mixing or inaccurate ratio can cause incomplete curing or surface defects.
Procedure
Before starting, ensure the floor is clean, dry, and primed according to system specifications. Mask skirting, joints, and delicate areas to prevent accidental application.
Pour the mixed epoxy putty onto the floor in manageable sections. Use a stainless steel trowel for even spreading, applying pressure to press putty firmly into defects or low spots. Maintain a layer thickness of approximately 1–2 mm.
Work systematically toward the exit to avoid walking on fresh putty. Feather edges and smooth transitions between sections to prevent visible ridges after curing. Check for pinholes or air pockets; if present, re-trowel the area for smoothness.
Allow the putty layer to cure fully—typically 8–12 hours at 20–25°C—before proceeding with sanding or the next coating layer. Proper ventilation helps evaporation and reduces curing time.
Fourth Coat: Self-Leveling Surface Coat
The fourth coat is the crucial self-leveling surface layer that gives epoxy flooring its seamless, uniform, and professional finish. High-precision materials and careful placement using notched trowels and spiked rollers result in a smooth, durable, and ultra-wear-resistant surface.
Objective
This stage is designed to provide the final surface quality for the floor by applying a self-leveling epoxy layer that automatically spreads out to create a flat, smooth finish. You focus on eliminating imperfections, air bubbles, and inconsistencies left from previous coats.
The self-leveling coat ensures excellent abrasion resistance, enhanced visual appeal, and a glossy or matte look, depending on your choice. Achieving a dust-free, even layer is essential for both performance and aesthetics, particularly for industrial, commercial, or showroom environments.
You also aim to seal any micro-pores and reinforce the underlayers. Uniform distribution across the floor area maximizes longevity and simplifies cleaning and maintenance.
Materials & Mixing Ratio
Use a high-quality Self-Leveling Epoxy Surface Coat recommended by your supplier, such as those produced by Shanghai Danshang Technology. Each component must be measured accurately to maintain optimal flow and curing properties.
Standard ratios for epoxy self-leveling systems are typically 2:1 by weight (part A resin to part B hardener), but always verify the specific manufacturer’s instructions. Incorrect mixing can lead to poor self-leveling or incomplete curing.
Prepare a checklist:
- Epoxy Self-Leveling Flooring components (A+B)
- Notched squeegees and trowels for spreading
- Spike rollers for de-aeration
- Spike shoes for mobility during application\
Mix components mechanically for 2-3 minutes at low speed to prevent air entrapment and ensure homogeneity.
Procedure
Begin by verifying the substrate is dust-free, dry, and properly primed. Pour the mixed material directly onto the floor in ribbon-like bands to speed coverage and reduce the risk of bubbles.
Distribute using a notched trowel or notched squeegee, setting the desired film thickness—usually 1–3 mm for industrial floors. Wear spike shoes at all times to avoid marking the fresh coat while moving across the area.
Immediately after spreading, use a spike roller to remove trapped air and aid in leveling. Roll systematically in a crosshatch pattern until all bubbles disappear.
Work quickly, as the pot life is limited—typically 20–30 minutes depending on temperature and mix size. Allow the self-leveling coat to cure undisturbed for the recommended time before proceeding to any final finishing or topcoat.
Strict adherence to these steps ensures a uniform, seamless epoxy floor with ultra-wear resistance.
Fifth Coat: Ultra-Wear-Resistant Topcoat
This stage provides exceptional abrasion resistance, enhanced slip resistance, and a UV-stable, seamless high-gloss finish. Proper material choice, correct mixing ratios, and precise roller technique are crucial for optimal performance.
Objective
Your primary goal with the fifth coat is to create an ultra-wear-resistant barrier that extends the service life of your floor. The polyurethane topcoat shields the underlying layers from mechanical wear, heavy foot and vehicle traffic, and chemical exposure.
Using a UV-stable polyurethane coating helps prevent color fading and yellowing, making it ideal for areas exposed to sunlight or intense lighting. This layer also optimizes the seamless high-gloss finish, contributing both to aesthetics and ease of cleaning.
For environments where slip resistance or safety is a priority, additives can be incorporated to meet industry standards. You ensure the floor’s durability, shine, and safety characteristics are maximized at this step.
Materials & Mixing Ratio
You need a three-component Polyurethane Ultra-Wear-Resistant Coating. Select a grade labeled as “UV-Stable” or “UV-Protect” for indoor and outdoor settings. Always confirm material compatibility with earlier epoxy layers.
The typical mixing ratio for the topcoat is:
| Component A (Base) | Component B (Hardener) | Componet C (White corundum) |
|---|---|---|
| 5 | 2 | 3 |
Mixing must be thorough—mechanical stirring at 300–400 rpm for 2–3 minutes is recommended. For anti-slip functionality, you can add quartz sand or slip-resistant microbeads at 2–5% by weight.
Wear protective gloves and goggles during preparation. Use only freshly-mixed product; do not re-use material after pot life expires.
Procedure
Make sure the epoxy underlayers are fully cured, dry, and free of dust or contaminants. Optimal substrate temperature is 10–30°C with humidity below 75%. Tape off edges for clean control lines.
Pour the mixed polyurethane topcoat onto the floor in equal ribbons. Use a high-quality roller and apply in overlapping strokes for a uniform finish. Maintain a wet edge to avoid lap marks and achieve a seamless high-gloss effect.
If increased slip resistance is required, broadcast slip-resistant aggregate evenly into the wet topcoat. Allow the coating to cure for 24–48 hours, with light foot traffic permitted after 24 hours and full cure reached within 7 days. Always follow material specifications for re-coat or service times.
Routine aftercare is simple: Use neutral detergents for cleaning and avoid harsh abrasives to preserve gloss and wear resistance.
