Field of Application and suitable substrates Casuprim HB Bonding Primer
Casuprim HB is used where concrete substrates are plastered using a gypsum-based plaster. Priming with Casuprim HB decreases the deleterious reaction between concrete and gypsum (ettringite formation) and provides the applied plaster with a good key and adhesion. At the same time the absorption capacity of the concrete is balanced. The maximum permissible moisture content of the concrete substrate should be < 3% CM. The substrate must be sound, dry, clean, and free of efflorescence, laitance, release agents and any other contaminants that may prevent proper adhesion.
Application Casuprim HB Bonding Primer
Casuprim HB may be applied by brush, roller or fine spray gun. When applied by machine spray application, Casuprim HB may be diluted with a small amount of water in order to achieve the correct spraying consistency. Before use Casuprim HB should be stirred vigorously. A bucket (20 kg) is sufficient for about 100 square meters, depending on the nature of the substrate.
