Epoxy Coatings for Garage Floors

If you’re planning to repair your Inexpensive Epoxy Coatings for Garage Floors Kitchener with an epoxy or polyasparagine coating, there are a few things you need to know to avoid problems later on.

Moisture In Concrete

Concrete mixes with water, that’s an obvious statement, but what happens when it hardens? Water combined with ash, sand, aggregate and water creates a chemical reaction that turns the mixture into a solid. The healing cycle, called hydration, is part of a chemical process. Excess moisture rises to the surface and leaves a trail. When moisture rises to the surface, the concrete hardens and the traces left after the water are air holes or veins. The pressure of moisture pushes up and through these pores to the surface.

There are two types of pressure that can cause coating problems. Has capillary and hydrostatic pressure. Hydrostatic pressure is reached when the concrete is under the slope. Humidity below grade creates enormous pressure, which is pushed through tiny air holes in the concrete. When it pushes up, it also pushes the salt to the surface. Capillary pressure has the same result with less pressure. However, moisture and salt can cause cracking and delamination of the coating.

Check The Humidity of Your Stove

The easiest way is to glue the plastic to the floor in several places. You can also put a thick rubber mat on the floor. If you have condensation on the bottom after 24-48 hours, you have a moisture problem. It is possible to get different readings at different times of the year. In colder climates, you will have minimal humidity during winter or early spring, which can increase as the soil thaws. If your concrete is higher grade and has a basement underneath, chances are you have little or no moisture.

Layer Selection

There are epoxy and polyprotic or polyurea products for Polyaspartic Garage Floor Coati. Whatever you choose, surface preparation is the most important first step. Cracks should be filled with polyurea filler for best results. The polyurea can be thin enough to fill the gap completely down. Your concrete may be 4 inches thick. A gap will run all the way. Fill the crack down with a filler material that hardens below the surface, absorbs into the crack walls and flexes, and blocks moisture from reaching the surface. There are also some heavy-duty epoxies used for impregnation which are excellent alternatives.

The next step is to etch, spray or grind the surface to give an increase in surface area or to open the pores of the concrete. Gel Acid Etching is a simple and effective method for creating shot peening concrete profiles. In shot peening, thousands of tiny ball bearings are blasted to the surface. Each operation wipes the surface like 100 grit sandpaper. This is the process before applying the epoxy coating.
