What are Polyaspartic and Polyurea Coatings?
Polyaspartic and polyurea coatings were developed over 19 years ago to coat steel to prevent corrosion. The high performance led to experimenting as a polyurea concrete coating. They start as two components that 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 top coat exemplified the quartz and chips containing a decorative result.
So simply they are a coating that protects the concrete garage floor. However 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. Fine-tuning the ability 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 rack product that is one size fits all, the product can be adjusted to fit the appliance. It’s resulted in a solution in Minnesota that has extreme temperatures and issues that are wide and varied 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 ideal start to thaw the moisture gets underneath the slab and pushes way up through the airholes and undesireable veins in concrete. This happens everywhere but is extreme in very cold climates. Polyurea and polyaspartic combinations have been created that have the unique capability wet or absorb into the concrete rather than just sticking 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 section 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 and incapacitated and start becoming worn concrete. This combined with de-icing salts from cars and trucks that are monitored onto the floor rapidly deteriorate concrete especially in Minnesota. Fine-tuning 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 section of the floor. With the right blend the concrete will break before the polyureas. What may seem undoable are now able to be fixed.
Flexibility Can be Adjusted
Due to the extreme conditions resulting in crumbled concrete the polyureas can be adjusted to be thin enough to fill a crack right 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. Cracks are like ports for moisture smoke. The ability to permanently fix a crack in the concrete floor prevents moisture pressure and salts from delaminating the top coating.
Creating a Not for Slip Surface.
Conscientious polyurea coating professionals add a not for 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 particles into each layer the coefficient of friction (non-slip) will always exist. Many coatings are too thick to build not for slip particles into each layer and are braodcast only at the surface. Not for Slip Particles in the surface will dislodge from use and become elusive fast.
The final Decorative Clothes
Scratching 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 some extent of wear. Polypaspartic polyureas have the unique capability be slightly sanded and recoated restoring the surface like new.
