Floor coating is an actual thermosetting resin that is applied as a coating. It is formed when you mix one part epoxide resin with one part polyamine hardener. The hardener acts as a catalyst and is what gives floor coating its strength.
Unlike paint that has to dry, floor coating actually cures. When the two parts are mixed, a chemical reaction is started which creates an exothermic curing process. This curing process produces polymer structures that are closely cross-linked giving floor coating its superior strength and durability. The end result is a coating that is much thicker than paint and bonds tenaciously to a properly prepared surface.
So what makes an floor coating one of the best finishes for your garage floor? Besides looking nice, the hardened and thick application that you get from floor coating creates a coating that is very durable and resilient to impacts, chipping, chemicals, stains, and surface abrasion. You don’t have to panic about damaging the floor if you drop a wrench or a bicycle falls over.
The thicker coating also does a great job of coating over minor imperfections such as small spider cracks and flaws in the concrete. Because floor coating is a topical sealer, it is also anti-dusting. Much of the dust in a garage is created from the powder that a cement floor can shed. Normal traffic on bare concrete can kick up this dusty powder that has a tendency of collecting on cars, tool benches, and storage items, as well as being tracked into the house.
As a topical coating it is also naturally moisture resistant. This is a great benefit for people who live in snowy climates. It makes for easy cleaning of icy brines and road salts that can collect on the floor during the winter. Just a little mild soap and water is all it takes. Dust and debris can be collected with a dust mop or soft broom when the floor is dry.
Depending on whether you added colored acrylic flakesto the floor and the type of topcoat used, some surfaces can be slippery when wet. For people who live in drier climates this usually isn’t an issue. If you want some extra grip however, you can add slip resistant aggregate to the final coat that will create a non-skid surface.
Floor coatings receive high reviews from the home mechanics and hobbyists as well. Since it is both chemical and stain resistant, oil, brake fluids, anti-freeze, gasoline, and other caustic car chemicals can easily be wiped up without worry – even if it sits for a while. Rolling tool boxes, jacks, and jack stands will not damage the floor either. It also brightens up the garage environment because it is very light reflective depending on what type of finish you choose.
As tough as this type of garage floor coating is, it’s not resistant to everything however. Welding is hard on floor coating because it can create burn marks from the hot slag that falls on it. It’s also not a good choice for garage floors that have moisture issues. The rate of moisture vapor transmissionfrom underneath the slab can cause floor coating to delaminate if it is too high.
A common question that pops up about floor coating garage floors is hot tire pick up. This is caused when the hot tires from your car can soften lessor quality coatings. The tires then cool down and contract after driving which causes the tire tread to literally grab and pull at the surface of the still soft coating. This process will actually cause the floor coating to delaminate as the tire pulls it up off the floor.
Hot tire pick up is a problem that is associated more with the lesser quality products such as store bought floor coating paint kits. These are usually water based coatings that are 50% solids at best and only 3 mils thick, as compared to 100% solids floor coating that is 10 mils or more thick. These thicker coating are generally found in quality commercial grade product or professionally installed coatings.
Because the thicker, multiple coat floor coating floors wear so well, warranties of up to 15 years or more for installation by professional installers is becoming common. Many manufacturers of 100% solids floor coating warranty the product against defects for the life of the floor.
