What Are Polyaspartic and Polyurea Coatings?
Polyaspartic and polyurea coatings were developed over 20 years ago to coat steel to avoid corrosion. The powerful 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 could be added and decorative chips or quartz could be broadcast to the wet coating. The most truly effective coat encapsulated the quartz and chips yielding a pretty result.
So simply they are a coating that protects the concrete garage floor. However they are far more sophisticated. When polyaspartic esters are included with 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 could be decreased. Adjusting the capability of the item implies that in the hands of a professional there’s finally a solution for the concrete floor.
Rather than having an off the shelf product that is one size fits all, the item could be adjusted to match the application. It has led to a solution in Minnesota that’s extreme temperatures and problems that are very different than anywhere else.
How They Stop Moisture Pressure
The concrete garage floor typically has extensive ground moisture and freeze problems that trap moisture in the ground. When ice and snow begin to melt the moisture gets underneath the slab and pushes upwards through the airholes and veins in concrete polyurethane. This happens everywhere but is extreme in cold climates. Polyurea and polyaspartic blends have already been created that have the unique capability to wet or absorb to the concrete rather than simply sticking 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 to the surface. When they cure they become area of the floor and a lasting moisture barrier.
How They Fix Damaged Concrete Floors
Salts which are pushed to the surface from moisture pressure settle on to the floor and start wearing down concrete. This along with de-icing salts from cars and trucks which are tracked onto the floor rapidly deteriorate concrete especially in Minnesota. Adjusting the capability of a polyurea to absorb into the surface means badly damaged floors could be fixed. Since the polyureas can soak into porous concrete they become area of the floor. With the best blend the concrete will break ahead of the polyureas. What might seem hopeless are now able to be fixed.
Flexibility Can Be Adjusted
Due to the extreme conditions resulting in cracked concrete the polyureas could be adjusted to be thin enough to fill a break all the best way to underneath, not only at the surface. Flexibility or elongation since it is referred could be increased and so 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 capacity to permanently fix a break in the concrete floor prevents moisture pressure and salts from delaminating the most 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 see 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 surface will dislodge from use and become slippery fast.
The Final Decorative Coats
Abrasion resistance could be adjusted so your floor with extreme surface abuse will endure on the long term. But when sand, dirt and de-icing salts hit the surface every floor can get some extent of wear. Polypaspartic polyureas have the unique capability to be slightly sanded and recoated restoring the surface like new.
