Polyaspartic and polyurea coatings were developed over 20 years ago to coat steel to avoid corrosion. The high end led to experimenting as a 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 utmost effective coat encapsulated the quartz and chips yielding an ornamental result.
So simply they are a coating that protects the concrete garage floor. However they are a lot more sophisticated. When polyaspartic esters are included with a polyurea the capabilities change with regards to the desired result. For example, adding polyaspartic esters increases the cure time. polyurea coating Use less and the cure time can be decreased. Adjusting the capability of the product means that in the hands of a specialist there is finally a remedy for the concrete floor.
Instead of utilizing an off the shelf product that’s one size fits all, the product can be adjusted to fit the application. This has led to a remedy in Minnesota that’s extreme temperatures and issues that will vary 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 begin to melt the moisture gets within the slab and pushes upwards through the airholes and veins in concrete. This happens everywhere but is extreme in cold climates. Polyurea and polyaspartic blends have now been created which have the unique power to wet or absorb into the concrete rather than simply sticking with the surface. Provided the top is ground the right way with professional grinding equipment the pores of the concrete are opened allowing the polyureas to soak into the surface. Once they cure they become the main floor and a permanent moisture barrier.
How They Fix Damaged Concrete Floors
Salts that are pushed to the top from moisture pressure settle on the ground and start wearing down concrete. This along with de-icing salts from cars and trucks that are tracked onto the floor rapidly deteriorate concrete especially in Minnesota. Adjusting the power of a polyurea to absorb into the top means badly damaged floors can be fixed. Since the polyureas can soak into porous concrete they become the main floor. With the right blend the concrete will break before the polyureas. What might seem hopeless may now be fixed.
Flexibility Can Be Adjusted
Because of the extreme conditions leading to cracked concrete the polyureas can be adjusted to be thin enough to fill a crack all the way to underneath, not only at the surface. Flexibility or elongation since it is referred can be increased therefore 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 crack 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 low slip feature into each coat. For floors with high traffic you will see some wear and every coating will wear with a 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 top will dislodge from use and become slippery fast.
The Final Decorative Coats
Abrasion resistance can be adjusted so that the floor with extreme surface abuse will endure over the long term. Nevertheless when sand, dirt and de-icing salts hit the top every floor will get some degree of wear. Polypaspartic polyureas have the unique power to be slightly sanded and recoated restoring the top like new.
