What Are Polyaspartic and Polyurea Coatings?
Polyaspartic and polyurea coatings were developed over 20 years ago to coat steel to stop corrosion. The high end generated experimenting as a concrete coating. They start as two components which can be mixed together basically as an epoxy and rolled on a concrete surface. Colored pigments could be added and decorative chips or quartz could be broadcast into the wet coating. The most truly effective coat encapsulated the quartz and chips yielding a pretty result.
So simply they are a layer that protects the concrete garage floor. However they are a lot more sophisticated. When polyaspartic esters are included with a polyurea the capabilities change with respect to the desired result. For example, adding polyaspartic esters increases the cure time. Use less and the cure time could be decreased. Adjusting the capability of the product means that in the hands of a professional there’s finally an answer for the concrete floor.
As opposed to having an off the shelf product that’s one size fits all, the product could be adjusted to match the application. It has resulted in an answer in Minnesota that has extreme temperatures and conditions that are different than anywhere else.
How They Stop Moisture Pressure
The concrete garage floor typically has extensive ground moisture and freeze conditions that trap moisture in the ground. When ice and snow begin to melt the moisture gets beneath the slab and pushes upwards through the airholes and veins in concrete. This happens everywhere but is extreme in cold climates. Polyurea and polyaspartic blends have already been created that have the unique ability to wet or absorb into the concrete rather than simply sticking with the surface polyurethane. Provided the top is ground the proper way with professional grinding equipment the pores of the concrete are opened allowing the polyureas to soak into the surface. If they cure they become the main floor and a permanent moisture barrier.
How They Fix Damaged Concrete Floors
Salts which can be pushed to the top from moisture pressure settle on the ground and start wearing down concrete. This along with de-icing salts from cars and trucks which can be tracked onto the floor rapidly deteriorate concrete especially in Minnesota. Adjusting the power of a polyurea to absorb into the top means badly damaged floors could be fixed. Since the polyureas can soak into porous concrete they become the main floor. With the best blend the concrete will break before the polyureas. What might appear hopeless are now able to be fixed.
Flexibility Can Be Adjusted
As a result of extreme conditions leading to cracked concrete the polyureas could be adjusted to be thin enough to fill a break all the best way to the underside, not merely at the surface. Flexibility or elongation as it is referred could be increased therefore the filler will move with the concrete. Yet another feature is that polyureas will cure deep in the crack even though their is moisture in the walls of the crack. Cracks are like vents for moisture vapor. The ability to permanently fix a break in the concrete floor prevents moisture pressure and salts from delaminating the very best coating.
Making a Non Slip Surface.
Conscientious polyurea coating professionals put in a non slip feature into each coat. For floors with high traffic you will see some wear and every coating will wear to some degree. By mixing the best size particles into each layer the coefficient of friction (non-slip) will always exist. Many coatings are too thick to construct non slip particles into each layer and are braodcast only at the surface. Non Slip Particles in the top will dislodge from use and become slippery fast.
The Final Decorative Coats
Abrasion resistance could be adjusted so that the floor with extreme surface abuse will endure over the long term. Nevertheless when sand, dirt and de-icing salts hit the top every floor are certain to get some extent of wear. Polypaspartic polyureas have the unique ability to be slightly sanded and recoated restoring the top like new.
