b. A mild Acid bath is done and then neutralized. This opens the pores of the concrete and prepares
it to bond with the next application. (An Acid Bath is NOT done for staining a Concrete Slab). For those interested
in staining concrete slabs, please see the information on About Acid Stain and Builder Information pages; the
following steps only apply to concrete overlays.
2. Base (skim) Coat. This step is common to all overlay applications.
a. Cracks in the surface are treated if needed.
b. A Skim or Scratch/Base coat is applied to the surface and allowed to dry.
*** The steps below are by style. Depending on the complexity of your desired surface, modifications may be made.
3. Texture Applications: There are several styles that fit this catagory (a Knock-Down finish is in this catagory).
a. Basic Spray Texture would have an additional Base Coat added before the Top Coat is Sprayed on. I feel the additional base
coat is needed to give strength to the final product. After the second Base Coat, the Top Coat is sprayed over a Stencil, Tape
or a Seamless pattern.
b. Flagstone coatings also receive two Base Coats for the same reason above. The next step is to apply a 1/2" Nylon Tape to
the surface to mark off the "rocks/stones".
c. The Flagstone pattern is then coated with the Top Coat and after a dry time, misted with additional colors.
d. The tape is then pulled off to reveal the pattern and the surface is then sealed.
4. Faux Slate/Tile Applications:
a. The Top Coat material is mixed and applied with a pool trowel to achieve a look that resembles a light Slate Texture or a
swirl-type texture found on some tiles.
b. After drying overnight, the desired pattern is marked and scored.
c. Stain is applied to the surface in several coats to achieve the desired color, tint and tone.
d. After an overnight dry, the surface is sealed.
e. NOTE: This texture may also be reffered to as a "Knock-Down" when it is done to resemble Cool Deck.
f. There are other variations of this style that can create a personalized tile unique to your home.
5. Micro-Finish Overlay:
a. The most common use of Micro-Finish is to overlay a slab that would not react well to acid stain. The final result is a surface
that actually achieves a higher degree of mottleing and tone than concrete.
b. A Micro-Finish job will get a second Base Coat.
c. Two applications of Micro-Finish are applied with a pool trowel. This process fills in the small voids in the surface and results
in a smooth even surface.
d. The floor is machine-sanded to further smooth the surface and remove any trowel marks.
e. The pattern is scored and the surface is stained in the desired color. After the stain works for about 4 hours, it is neutralized
f. Once the surface is dry it is sealed.
6. Thin-Stamped Overlay:
a. Texture Pave is the ultimate top-coat that is applied to the surface and accepts the stamp pattern.
b. A "Wet Bond" coat is put down in advance of the Texture Pave.
c. The Texture Pave is spread out with a Guage Rake to ensure a consistant ¼” application.
d. After about 2 hours the surface has set up enough to be stamped with the Texture Skin.
e. The Texxture Skin makes the Slate pattern in the surface.
f. After the Stamp, the material will dry over night.
g. The pattern is then scored and stained in the desired color.
h. Once the surface is dry it is sealed.
7. Sealer Options:
There are several sealers available and the choice of sealer should be determined by environment and use. Some of the overlay
styles/staining required longer dry times than others. Most surfaces can be sealed the day after staining.
a. CSS. This is the Primary sealer for Exterior applications. CSS is a 53% solids, UV inhibiting sealer. It penetrates the surface and
inhibits mold and mildew from getting a foot-hold on the surface.
b. AUS-G: This is a Aliphatic Urethane sealer. It is UV stable and offers higher abrasion resistance.
c. Clear Epoxy: This is the best sealer for Interior use. It cures up to over 14,000 PSI and is odorless.
d. Colored Epoxy: Colored Epoxy comes in 10 colors and is the best coating for areas such as loading
docks where high wear is the primary concern.
e. Wax: All interior applications receive coats of a commercial quality liquid wax. This wax is a 37.5% Solids commercial quality wax.
It is applied with a looped-end Rayon mop. The purpose of the wax is to provide a sacrificial coat to absorb the scuff marks and prolong the sealers life.
An Interior floor that recieves regular waxing will never have to be re-sealed.
