HS 200 is a premium, high-performance, single-component silane, acrylic 20% solids, 600 g/l, sealer designed for concrete or cement-based products. As with most acrylics, it
is vapor permeable and readily applies outside. However, HS-200 is specially formulated for extreme climates. The unique Silane formulation creates the nano-sealer technology that
deeply penetrates and reacts internally with cement, slowing moisture migration, efflorescence and intensifying bond capacity. Even in warmer climates, HS 200’s slower evaporating solvents will not “cotton candy” before the applicator can finish a tight, smooth surface. A single coat application will provide a UV shield, enhance the beauty, and protect the surface of the driveway.

How to Apply SureCrete HS 200 Acrylic Sealer:
Planning
1. Product is flammable. Interior applications, turn off all fuel-burning appliances and pilot lights.
2. Provide for ventilation so that vapors do not accumulate.
3. Select appropriate PPE (personal protection equipment). Use of a NIOSH-approved respirator may be required. Refer to SDS.
Mask all areas requiring protection.
Temperature/weather
1. Avoid application on extremely cold or hot days or during wet, foggy weather.
2. 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.
3. Do not apply outside if precipitation is forecast within 24 hours of application.
4. Substrate must be dry throughout all steps.
First coat
Rolling
1. Utilize a bucket grid to apply in a thin film.
2. Roller covers require a solvent-resistant core.
3. The correct nap size varies due to texture. For example ¾” is recommended for heavily textured patterns, while ¼” mohair is
APPLICATION
• Mechanically: diamond grinding or shot blasting b) 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.
c) Before recoating, prepare on-site a small test area on the
intended substrate to establish the compatibility of solvents and avoid blistering and delamination.
d) 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).
4. Do not allow puddling.
5. Exercise care to eliminate roller tracks through back rolling. Airless Spraying

1. Airless sprayer should be capable of a minimum .5 gpm discharge.
2. Tip size should be approximately .015” - .019” with 65° fan.
3. For horizontal surface utilize an 8” – 10” extension.
4. Maintain a wet edge between passes.
Pump-up Sprayer
1. Select solvent resistant sprayer.
2. Select fan or cone tip as preferred that can pass 20% solids product.
3. Have sufficient tips on hand to allow clean-up that will not interrupt application.
4. 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.
For single coat system: Allow 24 hours cure time prior to foot traffic.
Allow 72 hours cure time prior to vehicular traffic.
Second Coat
Applies identical to the first coat.
Allow 24 hours cure time before foot traffic.
Allow 72 hours cure time before vehicular traffic.
