What Are Polyaspartic and Polyurea Coatings?
Polyaspartic and polyurea coatings were developed over 20 years ago to coat steel to prevent corrosion. The powerful resulted in 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 can be added and decorative chips or quartz can be broadcast to the wet coating. The most effective coat encapsulated the quartz and chips yielding a pretty result.
So simply they’re a level 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 depending on the desired result. For instance, adding polyaspartic esters increases the cure time polyurea. Use less and the cure time can be decreased. Adjusting the ability of the product means that in the hands of a specialist there’s finally a remedy for the concrete floor.
In place of having an off the shelf product that is one size fits all, the product can be adjusted to fit the application. This has triggered a remedy in Minnesota that’s extreme temperatures and conditions that are very 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 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 now been created that have the initial capability to wet or absorb to the concrete rather than staying with 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. When they cure they become part 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 to the floor and start breaking down concrete. This combined with de-icing salts from cars and trucks which can be tracked onto the ground rapidly deteriorate concrete especially in Minnesota. Adjusting the power of a polyurea to absorb into the outer lining means badly damaged floors can be fixed. Because the polyureas can soak into porous concrete they become part of the floor. With the proper blend the concrete will break before the polyureas. What may appear hopeless can now be fixed.
Flexibility Can Be Adjusted
As a result of extreme conditions resulting in cracked concrete the polyureas can be adjusted to be thin enough to fill a crack all how you can the bottom, not merely at the surface. Flexibility or elongation since it is referred can be increased therefore the filler will move with the concrete. Yet another 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 capability to permanently fix a crack in the concrete floor prevents moisture pressure and salts from delaminating the most truly effective coating.
Creating a Non Slip Surface.
Conscientious polyurea coating professionals put in a non slip feature into each coat. For floors with high traffic there will be some wear and every coating will wear with a 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 build 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 on the long term. However 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.
