What Are Polyaspartic and Polyurea Coatings?
Polyaspartic and polyurea coatings were developed over 20 years back to coat steel to avoid corrosion. The high performance generated experimenting as a concrete coating. They start as two components that are mixed together basically like 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 effective coat encapsulated the quartz and chips yielding an ornamental result.
So simply they are a covering that protects the concrete garage floor. However they are far more sophisticated. When polyaspartic esters are put into a polyurea the capabilities change with regards to the desired result. Like, adding polyaspartic esters will increase the cure time. Use less and the cure time could be decreased. Adjusting the capacity of the item implies that in the hands of an expert there’s finally a solution for the concrete floor.
Rather than utilizing an off the shelf product that is one size fits all, the item could be adjusted to suit the application. It has led to a solution in Minnesota that’s 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 within the slab and pushes upwards through the airholes and veins in concrete polyurea. This happens everywhere but is extreme in very cold climates. Polyurea and polyaspartic blends have now been created that have the unique power to wet or absorb to the concrete rather than staying with the surface. Provided the outer lining is ground the proper way with professional grinding equipment the pores of the concrete are opened allowing the polyureas to soak to the surface. Once they cure they become part of the floor and a permanent moisture barrier.
How They Fix Damaged Concrete Floors
Salts that are pushed to the outer lining from moisture pressure settle on the ground and start deteriorating concrete. This along with de-icing salts from cars and trucks that are 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. Because the polyureas can soak into porous concrete they become part of the floor. With the best blend the concrete will break before the polyureas. What might seem hopeless may now be fixed.
Flexibility Can Be Adjusted
As a result of 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 merely at the surface. Flexibility or elongation because it is referred could be increased therefore the filler will move with the concrete. An additional 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 effective coating.
Developing 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 with a 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 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 on the long term. However when sand, dirt and de-icing salts hit the outer lining every floor will get some degree of wear. Polypaspartic polyureas have the unique power to be slightly sanded and recoated restoring the outer lining like new.
