Our Process

At Seal Saint Louis, our unique 5 step process protects your investment by leaving you with a beautifully restored and permanently sealed area. Our unique formula is perfect for your concrete, masonry, and wood surfaces while remaining environmentally friendly.

Step 1:

We start by masking off any surrounding areas to protect any other investments from damage.

Step 2:

Next we clean the area with our environmentally safe soap application which penetrates the material, opens its pores, and forces out oxidants. The cleaning process also includes a thorough scrubbing to help work the cleaning soaps into the material.

Step 3:

We then rinse the area with "hot water under pressure", not to be confused with pressure washing. This process balances the ph level of the area, and flushes the extracted oxidants away from the material without damaging the surface of your material like some other processes.

Step 4:

The sealing process is next where we apply a liberal application, or "flood coat" of our sealant which actually petrifies wood, and can strengthen concrete by as much as 23%.

Step 5:

We finish with site cleanup which entails removing any masking from surrounding areas, a full area rinse, and total site cleanup.
