Polyaspartic and polyurea coatings were developed over 20 years ago to coat steel to prevent corrosion. The good performance led to experimenting as a concrete coating. They start as two components which can be mixed together basically as an epoxy and rolled on a concrete surface. Colored pigments may be added and decorative chips or quartz may be broadcast in to the wet coating. The very best coat encapsulated the quartz and chips yielding a cosmetic result.
So simply they’re a level that protects the concrete garage floor. However they’re far more sophisticated. When polyaspartic esters are put into a polyurea the capabilities change depending on the desired result. As an example, adding polyaspartic esters will increase the cure time. polyurea coating Use less and the cure time may be decreased. Adjusting the capacity of the product means that in the hands of an expert there is finally an answer for the concrete floor.
Instead of utilizing an off the shelf product that is one size fits all, the product may be adjusted to suit the application. It has resulted in an answer in Minnesota that has 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 underneath 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 already been created which have the initial ability to wet or absorb in to the concrete rather than simply sticking 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 in 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 can be pushed to the outer lining from moisture pressure settle on to the floor and start wearing down concrete. This coupled with de-icing salts from cars and trucks which can be tracked onto a floor rapidly deteriorate concrete especially in Minnesota. Adjusting the power of a polyurea to absorb into the outer lining means badly damaged floors may be fixed. Since the polyureas can soak into porous concrete they become area of the floor. With the right blend the concrete will break ahead of the polyureas. What might seem hopeless may now be fixed.
Flexibility Can Be Adjusted
As a result of extreme conditions resulting in cracked concrete the polyureas may be adjusted to be thin enough to fill a break all the way to underneath, not just at the surface. Flexibility or elongation as it is referred may be increased 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 ability to permanently fix a break 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 have some wear and every coating will wear for 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 outer lining will dislodge from use and become slippery fast.
The Final Decorative Coats
Abrasion resistance may be adjusted so that the floor with extreme surface abuse will endure on the long term. But when sand, dirt and de-icing salts hit the outer lining every floor are certain to get some extent of wear. Polypaspartic polyureas have the initial ability to be slightly sanded and recoated restoring the outer lining like new.
