SUPERBASE (HS) ® is a one-part water-based acrylic coating that is easily applied without environmental concerns, and used as a base coat for either SUPERTHERM ® or SUNSHIELD ® . SUPERBASE (HS) ® can be used as a base coat to seal tar, asphalt, shingles, rubber, concrete, or wood roofs.
SURFACE PREPARATION
Surface must be clean from oil, rust, grease, salts, and films.
- Use general degreaser if needed.
- Clean surface using TSP (tri-sodium-phosphate) or a citrus cleaner to release dirt and degreaser residue.
- Pressure-wash if possible @ 3500 psi.
- Salt contamination on a surface can come as a result of salt water, fertilizers, and car exhaust. Use Chlor*Rid or equivalent to decontaminate surface if
salts are present. Acceptable levels: Nitrates: 5-10 mcg/cm², Sulfates: 5-10 mcg/cm², Chlorides: 3-5
mcg/cm²
Surface must be completely dry before applying.
- SUPERBASE (HS ® must be applied during proper temperatures (below) and the prescribed overcoat window of the coating over which it will be applied.
- Maximum Surface Temperature when applying: 150°F (65°C)
- Minimum Surface Temperature when applying: 40°F (5°C)
- Maximum Surface Temperature after curing: 300°F (149°C)
NOTE: Use RUSTGRIP ® as a primer when needed. Refer to RUSTGRIP ® technical data sheet for overcoat window.
NOTE: If pack rust or mill scale exist, it must be
removed by grit blast, power tool or needle gun.
Once removed, begin with Step 1 (power wash).
Mobile Homes:
- Use Mastic Sealing Tape over all leaks.
- Apply SUPERBASE (HS) ® over the tape.
- Apply SUPERTHERM ® over the entire roof for insulation.
MIXING
SUPERBASE (HS) ® should be mechanically mixed or mixed by hand for three minutes, then applied. |
APPLICATION METHODS
SUPERBASE (HS) ® can be applied by brush, roller or spray; however, the preferred method is by air or airless sprayer. It should never be applied directly over rust, nor should it ever be diluted or thinned.
- If application is by brush, use a soft bristle brush.
- If application is by roller, use a 1/4 inch nap roller.
- If application is by spray, use a standard airless sprayer (2 gallons/minute at 3,300 psi.) with a .029-.033 tip.
NOTE: The number of applications and the thickness of each should be in accordance with the job specifications.
NOTE: All filters should be removed from both the gun handle and spray machine prior to application, as they will trap the ceramics.
NOTE: Temperatures must always be a minimum of 5 degrees above the dew point during application.
CURE TIME
- One hour to touch at 70°F. and bright sun.
- Over-coating window begins at four hours at 70°F.
- Fully cures in ten day
TEMPERATURE
- Apply between 50°F. and 100°F.
- Store between 40°F. and 100°F.
CLEAN-UP EQUIPMENT
- After completion, spray system should be cleaned with soap and water.
- After completion, brushes and rollers can be cleaned with soap and water, stored and reused.
