What Are Polyaspartic and Polyurea Coatings?
Polyaspartic and polyurea coatings were developed over 20 years ago to coat steel to avoid corrosion. The good performance resulted in experimenting as a concrete coating. They start as two components which are 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 into the wet coating. The most truly effective coat encapsulated the quartz and chips yielding a pretty result.
So simply they’re a layer that protects the concrete garage floor. However they’re much more sophisticated. When polyaspartic esters are added to a polyurea the capabilities change with regards to the desired result. As an example, adding polyaspartic esters increase the cure time. Use less and the cure time can be decreased. Adjusting the ability of the merchandise implies that in the hands of a specialist there’s finally an answer for the concrete floor.
Rather than using an off the shelf product that is one size fits all, the merchandise can be adjusted to suit the application. It has led to an answer in Minnesota that’s extreme temperatures and issues that are different 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 start to melt the moisture gets underneath the slab and pushes upwards through the airholes and veins in concrete. This happens everywhere but is extreme in cold climates polyurethane. Polyurea and polyaspartic blends have been created that have the initial ability to wet or absorb into the concrete rather than simply staying with 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. If they cure they become the main floor and a permanent moisture barrier.
How They Fix Damaged Concrete Floors
Salts which are pushed to the surface from moisture pressure settle on the ground and start wearing down concrete. This combined with de-icing salts from cars and trucks which are tracked onto the ground rapidly deteriorate concrete especially in Minnesota. Adjusting the capability of a polyurea to absorb into the surface means badly damaged floors can be fixed. Considering that the polyureas can soak into porous concrete they become the main floor. With the right blend the concrete will break ahead of the polyureas. What may appear 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 crack all the best way to underneath, not only at the surface. Flexibility or elongation as it is referred can be increased therefore 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 ability to permanently fix a crack in the concrete floor prevents moisture pressure and salts from delaminating the top 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 see 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 surface 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 within the long term. But when sand, dirt and de-icing salts hit the surface every floor are certain to get some extent of wear. Polypaspartic polyureas have the initial ability to be slightly sanded and recoated restoring the surface like new.
