What Are Polyaspartic and Polyurea Coatings?
Polyaspartic and polyurea coatings were developed over 20 years ago to coat steel to avoid corrosion. The powerful led to experimenting as a concrete coating. They start as two components which can be mixed together basically such as an epoxy and rolled on a concrete surface. Colored pigments could be added and decorative chips or quartz could be broadcast into the wet coating. The most truly effective coat encapsulated the quartz and chips yielding a decorative result.
So simply they are a layer that protects the concrete garage floor. However they are a great deal more sophisticated. When polyaspartic esters are added to a polyurea the capabilities change with regards to the desired result. For example, adding polyaspartic esters increase the cure time. Use less and the cure time could be decreased. Adjusting the ability of the item means that in the hands of an expert there is finally a solution for the concrete floor.
Instead of utilizing an off the shelf product that’s one size fits all, the item could be adjusted to fit the application. It has resulted in a solution in Minnesota that has extreme temperatures and problems that are 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 beneath 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 already been created that have the initial power to wet or absorb into the concrete rather than staying 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 into the surface. If 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 breaking down concrete. This combined with de-icing salts from cars and trucks which can be tracked onto the ground rapidly deteriorate concrete especially in Minnesota. Adjusting the ability of a polyurea to absorb into the outer lining means badly damaged floors could be fixed. Considering that 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 may appear hopeless are now able to be fixed.
Flexibility Can Be Adjusted
Due to the extreme conditions leading to cracked concrete the polyureas could be adjusted to be thin enough to fill a crack all the best way to the bottom, not only at the surface. Flexibility or elongation because it is referred could be increased therefore the filler will move with the concrete. Yet another feature is that polyureas will cure deep in the crack even if 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 truly effective coating.
Making a Non Slip Surface.
Conscientious polyurea coating professionals put in a non 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 best size particles into each layer the coefficient of friction (non-slip) will always exist. Many coatings are too thick to build 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 could be adjusted so the floor with extreme surface abuse will endure over 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 power to be slightly sanded and recoated restoring the outer lining like new.
