What Are Polyaspartic and Polyurea Coatings?
Polyaspartic and polyurea coatings were developed over 20 years ago to coat steel to prevent corrosion. The high end led to experimenting as a concrete coating. They start as two components which can be mixed together basically such as an epoxy and rolled on a concrete surface. Colored pigments may be added and decorative chips or quartz may be broadcast to the wet coating. The top coat encapsulated the quartz and chips yielding an ornamental result.
So simply they’re a coating that protects the concrete garage floor. However they’re far more sophisticated. When polyaspartic esters are added to 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 may be decreased polyurea. Adjusting the capacity of the product implies that in the hands of a specialist there is finally a solution for the concrete floor.
Rather than having an off the shelf product that is one size fits all, the product may be adjusted to match the application. It has led to a solution in Minnesota that has extreme temperatures and conditions that will vary 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 start 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 very cold climates. Polyurea and polyaspartic blends have been created which have the initial capability to wet or absorb to the concrete rather than just staying with the surface. Provided the surface is ground the proper way with professional grinding equipment the pores of the concrete are opened allowing the polyureas to soak to the surface. Once they cure they become area of the floor and a lasting moisture barrier.
How They Fix Damaged Concrete Floors
Salts which can be pushed to the surface from moisture pressure settle on the floor and start wearing down concrete. This along with de-icing salts from cars and trucks which can be tracked onto a floor rapidly deteriorate concrete especially in Minnesota. Adjusting the power of a polyurea to absorb into the surface means badly damaged floors may be fixed. Because the polyureas can soak into porous concrete they become area of the floor. With the proper blend the concrete will break before the polyureas. What might seem hopeless can now be fixed.
Flexibility Can Be Adjusted
Because of the extreme conditions causing cracked concrete the polyureas may be adjusted to be thin enough to fill a crack all the best way to underneath, not just at the surface. Flexibility or elongation because it is referred may be increased therefore the filler will move with the concrete. One more feature is that polyureas will cure deep in the crack even if their is moisture in the walls of the crack. Cracks are like vents for moisture vapor. The capacity to permanently fix a crack in the concrete floor prevents moisture pressure and salts from delaminating the most truly effective coating.
Developing a Non Slip Surface.
Conscientious polyurea coating professionals add a non slip feature into each coat. For floors with high traffic there will be some wear and every coating will wear to some degree. By mixing the proper size particles into each layer the coefficient of friction (non-slip) will always exist. Many coatings are too thick to create non slip particles into each layer and are braodcast only at the surface. Non Slip Particles in the surface will dislodge from use and become slippery fast.
The Final Decorative Coats
Abrasion resistance may be adjusted so your floor with extreme surface abuse will endure within the long term. However when sand, dirt and de-icing salts hit the surface every floor will get some degree of wear. Polypaspartic polyureas have the initial capability to be slightly sanded and recoated restoring the surface like new.
