Polyaspartic and polyurea coatings were developed over 20 years ago to coat steel to stop corrosion. The powerful resulted in experimenting as a concrete coating. They start as two components that are mixed together basically such as an epoxy and rolled on a concrete surface. Colored pigments could be added and decorative chips or quartz could be broadcast to the wet coating. The most effective coat encapsulated the quartz and chips yielding an attractive result.
So simply they’re a coating that protects the concrete garage floor. However they’re a whole lot more sophisticated. When polyaspartic esters are included with a polyurea the capabilities change with regards to the desired result. For instance, adding polyaspartic esters increase the cure time. polyurea coating Use less and the cure time could be decreased. Adjusting the capability of the product means that in the hands of a specialist there is finally an answer for the concrete floor.
Instead of using an off the shelf product that is one size fits all, the product could be adjusted to fit the application. This has led to 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 now been created that have the initial capability to wet or absorb to the concrete rather than just sticking with the surface. Provided the top is ground the right way with professional grinding equipment the pores of the concrete are opened allowing the polyureas to soak to the surface. If they cure they become part of the floor and a lasting moisture barrier.
How They Fix Damaged Concrete Floors
Salts that are pushed to the top from moisture pressure settle on the ground and start deteriorating concrete. This along with de-icing salts from cars and trucks that are tracked onto a floor rapidly deteriorate concrete especially in Minnesota. Adjusting the capability 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 part of the floor. With the right blend the concrete will break before the polyureas. What may appear hopeless are now able to be fixed.
Flexibility Can Be Adjusted
As a result of extreme conditions causing cracked concrete the polyureas could be adjusted to be thin enough to fill a crack all the best way to the underside, not only at the surface. Flexibility or elongation since it is referred could be increased therefore the filler will move with the concrete. An additional 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 crack 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 there will be some wear and every coating will wear to some degree. By mixing the right 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 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 will get some extent of wear. Polypaspartic polyureas have the initial capability to be slightly sanded and recoated restoring the top like new.
