Installing the Acrylistain Finish
by Ethan Schneider
- Prepare concrete by either acid etching and power washing or Mechanically abrading.
- Apply skim coat in color of choice using hook trowel technique to create a vacuum under the trowel in order to create a stone like texture.
(skim mixture is 5 ½ qts. Modifier to 1 bag of grout with one cup of colorant.) - Allow skim coat to dry. Dry time may take from several to 24 hours depending on temperature.
- Flat scrape and or rock mop then broom and blow the surface twice.
- Apply acrylistain mixture.
Acrylistain mixture is ( ¼ cup colorant to 1 gal. of water) mix colorant and water in a standard pump sprayer. This mix ratio is a starting point and can be adjusted by adding more or less colorant to achieve the desired result. - Lightly mist plain water over area to be stained then apply stain mixture in a random circular pattern allowing stain to pool slightly in some areas and not in others. You can apply more than one stain color at a time. Be careful not to overlap the colors too much so as not to lose the mottled effect.
- Allow the acrylistain to dry. Exterior jobs 75 degrees allow to dry for several hours before sealing. 2 to 10 hours depending on how much stain is applied, whether or not the area is in direct sun light, humidity, and air movement. Indoors, allow to dry for a minimum of 24 hours before applying any sealers. It is important to have air movement and ventilation on interior applications in order for the product to completely dry out. You do not want to apply sealer if the floor is not completely dried out.
- Apply sealer of choice.
Acceptable sealers:
Pro-seal 200 for both interior and exterior application.
Aquathane 6000 for both interior or exterior applications where low VOC’s are required or odor is an issue.
Rapid Armor high build epoxy.
Be sure to view "Acrylistain" videos in your Tech Tips DVD’s and in the "product application tips section" located on the dealer website before attempting this procedure.
Always make a sealed sample board with the skim and spray colors you intend to use and have it approved by your customer before doing the installation. Contact the CTI tech department with any questions.
