What are Polyaspartic and Polyurea Coatings?
Polyaspartic and polyurea coatings were developed over twenty years ago to coat steel to prevent corrosion. The high performance led to trial and error as a polyurea concrete coating. They start as two components that are 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 into the wet coating. The top coat summarized the quartz and chips glorious a decorative result.
So simply they are a coating that protects the concrete garage floor. They also are much more sophisticated. When polyaspartic esters are added to a polyurea the capabilities change depending on the desired result. For example, adding polyaspartic esters will increase the cure time. Use less and the cure time can be decreased. Changing the capacity of the product means that in the hands of a professional there is finally a solution for the concrete floor.
Instead of using an off the corner product that is one size fits all, the product can be adjusted to fit the application form. It has resulted in a solution in Minnesota that has extreme temperatures and issues that are very different than anywhere else.
How they Stop Moisture Pressure
The concrete garage floor typically has extensive ground moisture and freeze them issues that trap moisture in the ground. When ice and compacted snow start to burn the moisture gets underneath the slab and pushes up wards through the airholes and problematic veins in concrete. This happens everywhere but is extreme in very cold climates. Polyurea and polyaspartic combines have been created that have the unique capacity wet or absorb into the concrete rather than just adhering to the surface. Provided the surface is ground the right way with professional grinding equipment the pores of the concrete are opened allowing the polyureas to soak into the surface. When they cure they become area of the floor and a permanent moisture barrier.
How they Fix Damaged Concrete Floors
Salts that are pushed to the surface from moisture pressure settle in the grass and start deteriorating concrete. This combined with de-icing salts from cars and trucks that are followed onto the floor rapidly worsen concrete especially in Minnesota. Changing the ability of a polyurea to absorb into the surface means badly damaged floors can be fixed. Since the polyureas can soak into porous concrete they become area of the floor. With the right blend the concrete will break before the polyureas. What may seem not possible is now able to be fixed.
Flexibility Can be Adjusted
Due to the extreme conditions resulting in broke concrete the polyureas can be adjusted to be thin enough to fill a crack entirely to the bottom, not just at the surface. Flexibility or elongation as it is referred can be increased so the filler will move with the concrete. An additional feature is that polyureas will cure deep in the crack even when their is moisture in the walls of the crack. Fractures are like grills for moisture steam. The ability to permanently fix a crack in the concrete floor prevents moisture pressure and salts from delaminating the top coating.
Creating a Low Slip Surface.
Conscientious polyurea coating professionals add a low 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 dust into each layer the coefficient of friction (non-slip) will always exist. Many coatings are too thick to build low slip dust into each layer and are braodcast only at the surface. Low Slip Dust in the surface will dislodge from use and grow smooth fast.
The final Decorative Wear
Damaging the teeth resistance can be adjusted so that the floor with extreme surface abuse will endure over the long term. However when sand, dirt and de-icing salts hit the surface every floor will get a point of wear. Polypaspartic polyureas have the unique capacity be slightly sanded and recoated restoring the surface like new.
