• Solvent resistance feature
• Excellent low environmental impact construction material
Material Feature :
• Custom weight: approx. 1.05 g/cm3
• pH-value: approx. 11
Colour Tint : Milky White
Application area should be hard, dry and clean. Remove dust and oil. Repair damaged areas using the KEIM Concretal concrete repair system.
For pre-treatment of highly absorbent application surfaces:
Apply undiluted KEIM Concretal-Fixativ with a brush.
As diluent on normal flat application surfaces for concrete opaque protective coatings:
KEIM Concretal-W/Concretal-W-Grob. Depending on absorbence of surface, add KEIM Concretal-Fixativ in to KEIM Concretal- W as max 10% (Maximum 2.5 liter dilution per 25 kg of paint) and stir. Use undiluted KEIM Concretal-W for topcoat.
Depending on the absorbency of the application surface, mix about 20-50% KEIM Concretal-Fixativ for KEIM Concretal-Lasur (approximately 0.2-0.5 liters per liter of Lasur) for the primer layer. Use topcoat undiluted KEIM Concretal-Lasur.
As a diluent for low pigment / creative use:
Depending on the desired final coat, KEIM Concretal-Lasur can be diluted with KEIM Concretal-Fixativ in the primer and top coat at the desired ratio.
For more information for Concretal-Fixativ use with KEIM Concretal-W and KEIM Concretal-Lasur, refer to the relevant technical data sheet of the specified products.
Air and surface temperature: > + 5°C
Drying time: A drying time of at least 12 hours must be ensured between the pretreatment and the primer and between the coats.
Consumption: For pre-treatment on a smooth application surface: Approx. 0,1–0,2 lt/m2 KEIM Concretal-Fixativ. The stated consumption value is a guide and depends on the absorbency and structure of the application surface. Exact consumption values can be determined by staining the test areas on the application surface.
After application, clean tools with water immediately.
