How to Epoxy a Garage Floor
Construction Process for a 2mm Thick Epoxy Floor Coating in an Underground Garage
1. Primer Application Steps:
- Clean the floor: Thoroughly clean the floor to remove dust, oil, and other contaminants.
- Grind the floor: Use sandpaper or a grinder to abrade the floor surface to provide better adhesion.
- Mix the primer: Mix components A and B of the primer according to the ratio specified in the product instructions, stirring until uniform.
- Apply the primer: Use a roller or brush to apply the primer evenly across the floor, ensuring a consistent coating thickness.
- Drying time: Allow the primer to dry completely as indicated in the product instructions.

Important Notes:
- The choice of primer should be based on the specific needs of the underground parking garage. Select an epoxy primer with good adhesion and resistance to penetration.
- Before primer application, ensure the floor is clean and dry to prevent dust and moisture from affecting the primer.
- The primer should be applied evenly, avoiding missed spots or uneven thickness. Areas with severe bubbling can be re-rolled once.

2. Mortar Intermediate Coat Application Steps:
- Clean the floor: Ensure the floor is clean, dust-free, and free of oil and debris.
- Mix the mortar intermediate coat material: Mix components A and B of the mortar coat material according to the ratio specified in the product instructions, stirring until uniform.
- Apply the mortar intermediate coat: Use a trowel to apply the mortar coat material evenly across the floor, filling defects and leveling the surface.
- Drying time: Allow the mortar coat material to dry completely as indicated in the product instructions.

Important Notes:
- The choice of mortar intermediate coat material should be based on the specific needs of the underground parking garage. Select an epoxy mortar coat material with wear-resistant and pressure-resistant properties.
- Before applying the mortar coat, ensure the floor is clean and dry to prevent dust and moisture from affecting the material. The application should be even, avoiding uneven thickness.
3. Putty Layer Application Steps:
- Clean the floor: Ensure the mortar layer floor is clean, dust-free, and free of oil and debris.
- Mix the epoxy putty material: Mix components A and B uniformly according to the ratio specified in the product instructions, then add a certain proportion of quartz powder and stir until uniform.
- Apply the putty layer: Use a scraper to apply the epoxy putty material evenly across the floor, filling minor surface defects and smoothing the surface.
- Drying time: Allow the putty layer to dry completely as indicated in the product instructions.

Important Notes:
- The choice of epoxy putty material should be based on the specific needs of the underground parking garage, selecting a product with good defect-filling and surface-leveling properties.
- Before applying the putty layer, ensure the floor is clean and dry to prevent dust and moisture from affecting the layer.
- The putty layer should be applied evenly, avoiding uneven thickness.
4.Topcoat Application Steps:
- Clean the floor: Ensure the floor is clean, dust-free, and free of oil and debris.
- Mix the epoxy topcoat material: Mix components A and B of the topcoat according to the ratio specified in the product instructions, stirring until uniform.
- Apply the topcoat: Use a roller or spray gun to apply the epoxy topcoat evenly over the putty layer surface, ensuring a consistent coating thickness.
- Drying time: Allow the topcoat material to dry completely as indicated in the product instructions.

Important Notes:
- The choice of epoxy topcoat should be based on the specific needs of the underground parking garage. For main driveways, select a product with wear-resistant, anti-slip, and easy-to-clean properties. For parking space areas, use a plain finish topcoat. Reasonable design can help reduce costs.
- Before topcoat application, ensure the putty layer is clean and dry to prevent dust and moisture from affecting the topcoat.
- The topcoat should be applied evenly, avoiding drips, missed spots, and uneven thickness.
Please note: After the topcoat dries, the floor can bear foot traffic after 24 hours but should not be subjected to heavy pressure. Normal use can resume after 7 days (once fully cured).
