This product contains a hybrid, self-cross-linking, acrylic resin with built-in water repellence and tenacious penetration and adhesion. It contains no wax or silicone additives. The coating is chemical resistant, durable, does not blush, has long solids retention, and is easy to clean. Super WB is non-flamma(more...)
SURFACE PREPThe principles for surface preparation for Super WB are aligned with other coating systems for cement based overlays and products, the substrate must be:
- Clean: The surface must be free of dust, dirt, oil, grease, paints, glues, non- acrylic sealers, curing agents, efflorescence, chemical contaminants, rust, algae, mildew and other foreign matter that may serve as a bond breaker.
- Cured: Cement-based overlays typically cure sufficiently overnight (refer to specific SureCrete overlay TDS.) Other cement-based products may require up to 28 days depending on temperatures & humidity.
- Sound: No system should be placed on cement based overlay that is flaking or spalling; substrate must be sound. If the surface is delaminating, then diamond grinding, shot blasting, or other mechanical means should be used to remove the delaminating areas.
- Profiled: Customarily cement based overlays do not require profiling. For other cement-based products proper profile should follow the standard established by the International Concrete Repair Institute (ICRI) Technical Guideline no. 03732 for Concrete Surface Profile (CSP). The established profile is categorized as CSP-1. To properly profile some cement-based products (especially exterior applications) use a pressure washer equipped with a turbo-tip and SCR (see SCR TDS). In one step SCR profiles, cleans, and provides a measure of degreasing. Some substrates may require more aggressive profiling through diamond grinding or shot blasting.
- Any old, loose and flaky sealer that is still present must be removed.
- Chemically: Fast-Strip Plus, Enviro-Strip (see appropriate TDS), or other commercial stripper.
- Mechanically: diamond grinding or shot blasting.
- This product should only recoat an existing solvent based acrylic. Determine a substrate’s unknown existing sealer by placing a paper towel saturated with xylene over a small area. Cover the towel with plastic and allow it to remain in place for 15 minutes. Solvent based acrylic may feel slippery to the touch, but water based acrylic turns into a slimy mess that can be scraped off easily.
- Before recoating, prepare on-site a small test area on the intended substrate to establish compatibility of solvents and avoid blistering and delamination.
- Recoat applications may be complete with a single coat, always evaluate surface to see if a second coat is needed. Best performance is achieved through thin coat(s).
- Provide for ventilation so that vapors do not accumulate.
- Select appropriate PPE (personal protection equipment). Use of a NIOSH approved respirator may be required. Refer to SDS.
- Avoid application on extremely cold or hot days or during wet, foggy weather
- Apply with ambient and surface temperatures ranging above 50°F (10°C) and below 90°F (32°C) and that will remain within ranges for at least 24 hours following application.
- Do not apply outside if precipitation is forecast within 24 hours of application.
- Substrate must be dry throughout all steps.
Mechanically mix with “Jiffy” style mixer blade for 3 minutes at medium speed for complete dispersal of pigments. Use caution not to entrain air during mixing.First Coat
- Utilize a bucket grid to apply in a thin film.
- Roller covers require a solvent resistant core.
- The correct nap size varies due to texture. For example ¾” is recommended for heavy textured patterns, while ¼” mohair is recommended for very smooth surfaces.
- Do not allow puddling.
- Exercise care to eliminate roller tracks through back rolling.
- Airless sprayer should be capable of a minimum .5 gpm discharge.
- Tip size should be approximately .015” - .019” with 65° fan.
- For horizontal surface utilize an 8” – 10” extension.
- Maintain a wet edge between passes.
- Select solvent resistant sprayer.
- Select fan or cone tip as preferred that can pass 30% solids product.
- Have sufficient tips on hand to allow clean-up that will not interrupt application.
- If necessary, backroll sprayed area to lay product flat.
When first coat is able to be walked on, it may receive a second coat. Customarily two thin coats achieve best performance.Second Coat
