What Are Polyaspartic and Polyurea Coatings?
Polyaspartic and polyurea coatings were developed over 20 years ago to coat steel to avoid corrosion. The high performance resulted in 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 can be added and decorative chips or quartz can be broadcast to the wet coating. The most truly effective coat encapsulated the quartz and chips yielding a cosmetic result.
So simply they’re a layer that protects the concrete garage floor. However they’re a whole lot more sophisticated. When polyaspartic esters are put into a polyurea the capabilities change depending on the desired result. Like, adding polyaspartic esters will increase the cure time. Use less and the cure time can be decreased. Adjusting the capacity of the merchandise means that in the hands of an expert there is finally a solution for the concrete floor.
Instead of having an off the shelf product that’s one size fits all, the merchandise can be adjusted to match the application. It has led to a solution in Minnesota that has extreme temperatures and issues that will vary than anywhere else.
How They Stop Moisture Pressure
The concrete garage floor typically has extensive ground moisture and freeze issues that trap moisture in the ground. When ice and snow begin to melt the moisture gets within the slab and pushes upwards through the airholes and veins in concrete. This happens everywhere but is extreme in cold climates polyurea. Polyurea and polyaspartic blends have now been created that have the initial capability to wet or absorb to the concrete rather than sticking to the surface. Provided the outer lining is ground the right 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 permanent moisture barrier.
How They Fix Damaged Concrete Floors
Salts which can be pushed to the outer lining from moisture pressure settle on the ground and start wearing down concrete. This combined with de-icing salts from cars and trucks which can be tracked onto a floor rapidly deteriorate concrete especially in Minnesota. Adjusting the ability of a polyurea to absorb into the outer lining means badly damaged floors can be fixed. Since the polyureas can soak into porous concrete they become area of the floor. With the best blend the concrete will break prior to the polyureas. What may seem hopeless are now able to be fixed.
Flexibility Can Be Adjusted
Due to the extreme conditions causing cracked concrete the polyureas can be adjusted to be thin enough to fill a break all the best way to the bottom, not only at the surface. Flexibility or elongation as it is referred can be increased so the filler will move with the concrete. One more feature is that polyureas will cure deep in the crack even when their is moisture in the walls of the crack. Cracks are like vents for moisture vapor. The capacity to permanently fix a break in the concrete floor prevents moisture pressure and salts from delaminating the utmost effective coating.
Developing a Non Slip Surface.
Conscientious polyurea coating professionals add a non slip feature into each coat. For floors with high traffic you will have 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 outer lining will dislodge from use and become slippery fast.
The Final Decorative Coats
Abrasion resistance can be adjusted so the floor with extreme surface abuse will endure over the long term. Nevertheless when sand, dirt and de-icing salts hit the outer lining every floor can get some degree of wear. Polypaspartic polyureas have the initial capability to be slightly sanded and recoated restoring the outer lining like new.
