- Applications - Crestamould® B12R Sealer should be applied by brush. Rollers will not get the sealer into the surface cells. Coverage is approx. 2.5m²/liter (100 sf/ gallon). It is important to spread the material thinly and avoid excess accumulation. Any excess will exotherm and melt the polystyrene. Allow 1.5 -2 hours between the application of the catalyzed Crestamould® B12R Sealer and subsequent lamination or spray-up. It works best on expanded and extruded polystyrene foams with a min. density of 30 kg/m³, or a min. compressive strength of 40 psi.
- Mixing - Before using, thoroughly mix contents in the 19 liter (5 gallon) pail using a mechanical mixer. Mixing the liter (quart) can by hand is sufficient. Do not remove any crestamould B12R from container before mixing.

Technical Details & Test Data
- Polystyrene Foams Suitable for Sealer Application
Crestamould® B12R Sealer works best on expanded and extruded polystyrene foams with a min. density of 22 kg/m³, or a min. compressive strength of 40 psi. The table below provides more exact information - the mid-range foams are best suited. The lower densities may still be suitable but may show various level of attack on the foam surface. We recommend appropriate tests for the foams to be used.

Storage & Handling
- Storage
For maximum shelf life, store Crestamould® B12R Sealer in a cool, dry area, maintaining a temperature between 10°C - 20°C. Avoid storing in heat or direct sunlight. Always allow Crestamould® B12R Sealer to reach shop temperatures before using. Periodically invert pails (store upside down) to prolong shelf life.
