Step 1—Pressure Washing
Make arrangements with customer to pressure wash at least 2 days prior to installation. The purpose of this is to remove all mildew, dirt, old paint and loose particles that may inhibit coating to adhere. While doing the pressure washing tap down all loose nail heads.
Step 2—Applying Primer
Moisture test wood and make sure reading is 20% or below. If not, allow more time for drying. Tape off and cover all areas that will not be coated. Mixture for primer is 1 gallon of primer for approx. 300 sq. ft. add 1 pint of paint for covering wider spaced boards. (adding paint is optional but will help creep into spaces between boards). Prime area with sprayer or roller (roller thickness may be less than ¾ inch). Try to get in cracks and cover nail heads thoroughly. The day before priming apply an aerosol rust covering product to damp and rusted nail heads. This will prevent nail heads from bleeding through at a later date.
Step 3—Applying Coating
Mixture for coating is 1 gallon of resin to 1 gallon of paint to 1 twelve pound bag of aggregate. This will cover anywhere from 100 to 150 sq. ft. with 2 coats depending on condition of surface.
Pour 1 gallon of resin in a 5 gallon bucket. Pour 1 gallon of Satin or Semi-Gloss Acrylic Latex Water Based paint in Bucket and mix for 1 minute. Slowly add aggregate while mixing. Thoroughly mix 2 or 3 minutes until smooth. Make sure no white particles are visible. Let sit for 1 or 2 minutes then mix again for 1 minute. The consistency you are looking for is similar to pancake batter. Do not create air vortex while mixing as adding air will cause product to set up and get hard before you are able to roll it on. Keeping the paddle completely in mix will help avoid vortex.
Apply with ¾ inch nap roller on wood and ½ inch roller on concrete. Apply first coat generously but understand that the second coat will really fill in all cracks when applied generously . Allow drying for a minimum of 30 minutes before applying second coat. Tape off area and advise customer to keep off for 24 hours.
Clean-up to be done with fresh water.
