As with most acrylics it is vapor permeable and readily applies outside. However, HS 200LV is specially formulated for extreme climates where a low VOC sealer is required. Its nano-sea(more...)
The principles for surface preparation for HS 200LV are aligned with other coating systems placed on concrete or cement based 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: Any concrete must be sufficiently cured to have complete hydration, approximately 28 days depending on temperatures & humidity. Some cement-based products may cure sufficiently within 2 – 3 days.
- Sound: No system should be placed on concrete or cement-based products that are flaking or spalling. If the surface is delaminating, then diamond grinding, shot blasting, or other mechanical means should be used to remove the delaminating areas.
- Profiled: 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.
The most common means to properly profile many concrete slabs (especially exterior slabs) is through the 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 concrete slabs that are hard troweled may require more aggressive profiling through diamond grinding or shot blasting. Some cement-based products do not require profiling.
HS 200LV’s silane, acrylic formula creates the premier choice to reseal or refresh an existing decorative concrete project. The surface should be cleaned with a pressure washer and SCR (see SCR TDS).
- 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).
- Product is flammable. Interior applications, turn off all fuel burning appliances and pilot lights.
- 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.
Mask all areas requiring protection; product will stick to just about everything.
Temperature / Weather
- 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 12 hours following application.
- Do not apply outside if precipitation is forecast within 24 hours of application.
- Substrate must be dry throughout all steps.
Mixing (applicable only to matte finish)
Mechanically mix with “Jiffy” style mixer blade for 3 minutes at medium speed for complete dispersal of matting agent. Use caution not to entrain air during mixing. No mixing is required for gloss finish.
- 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 20% 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. While many applications are complete with a single coat, always evaluate surface to see if a second coat is needed.
