How to apply epoxy garage floor coating
Errors resulting from poor epoxy flooring application can be very expensive. You might find that you need to redo it again because you do not want to live with poor looks on the floor. This guide will help you through the installation process for single coat 100% solids epoxy garage floor kits, 100 percent solids epoxy base coat -- whether it has color flakes or does not have -- and a clear polyurethane, polyurea, or epoxy top coat.
Most of the guides provided in many videos and online articles have scanty details, which cause applicator errors because the applicator usually find that they have to guess some moves. Therefore these errors can be reduced significantly when the applicator fully understands the process.
Do it with another person (2 people at minimum): Application of metallic epoxy floor paint and metallic epoxy pigments requires a minimum of two people to carry out because epoxy flooring systems are time sensitive. Two people not only reduce the errors related to that but will also cover a wide range of area within a shorter duration.
Type of epoxy kit: Single coat epoxy paint kits are water or solvent-based. They are much thinner and their longer pot life allows use of a roller on a paint tray.
Check the manufacturer’s guide: Although this guide can go a long way in helping you to install an metallic epoxy floor coating and metallic epoxy pigments, you should cross check with the guide from the manufacturer in order to get the process right at every stage. You might need to read the application instruction twice and, where need be, confirm with the manufacturer or the vendor before starting off. Most of them provide toll-free numbers.
Prepare the garage floor properly: Many of the errors resulting from garage epoxy floor coating applications are due to poor preparation of the garage floor, which is the most difficult to achieve. The first step begins with inspecting the floor even before purchasing any epoxy flooring or coating. For instance, it will not adhere to painted or sealed concrete including seal products applied on concrete. You might need to prepare the floor for epoxy floor coatings for concrete by mechanically grinding to remove the sealers.
You might want to test if a concrete floor has a sealer by pouring water on it: there probably is a sealer if the water beads up without turning the surface darker. If the concrete darkens as the water sips into the concrete then there is no sealer.
You can also poor acid to prepare the concrete if unsure whether there is a sealer -- this is called etching. However, try by testing with a small portion as that can help you know if you have a sealer on the concrete: if the acid turns yellow and starts to fizz, then there is no sealer, but if it merely sits on the concrete, then you have a sealer.
Garage floor preparation for epoxy floor coatings for concrete also includes checking for and repairing cracks, pits and spalls. Interlocking tiles or garage floor mats may be used instead of garage floor covering when there are extensive cracks and repairs to be made.
Allow up to 30 days on minimum for a typical 4” thick slab if you just poured them concrete, before applying the epoxy coating epoxy.
The floor should also be cleaned thoroughly to free it of any oils and greasy residues before applying metallic epoxy floor pigments.
Profiling will also help expose pores in the surface so the epoxy will flow into them and make a good bond. This is done by acid etching or grinding the surface.
Moisture test concrete
Watch out for damp concrete areas and efflorescence, which is a white powdery substance appearing on surface and formed when moisture coming from beneath the slab reacts with excess lime and salts present in the concrete and then the whole chemical reaction product dries up. It can also be realized if you live in a humid area. It should be removed to avoid damage of epoxy coating. Calcium chloride test will help you discover if there is moisture: however, most epoxy flooring products can work with up to 4 lbs of moisture flow per 1000 feet square per 24 hours.
The next step is to gather the right tools and do the application.
