"Solvent-free silicate-based consolidating agent for cement-bonded substrates.
For internally weak cement-bonded substrates and surfaces of crumbling cementitious screeds. To prevent the formation of a film layer that hinders adhesion, and to facilitate adhesion of the next treatment, sprinkle dry sand on the surface of the last layer. The substrate should be clean, dry, and free from oil, grease, paint marks, and loose parts.
Technical Data: Drying time: depends on the substrate's absorbency. Consistency: liquid. Color: transparent. Flammable: no. Application temperature: between +5°C and +35°C. Shelf life: 24 months. Protect from frost. Application: by roller, brush, or watering can.
Material Requirement 0.5-0.7 kg/m2.
Packaging 25 kg cans
APPLICATION AREA
Prosfas can be used for the following:
• Deep strengthening of cement-bonded substrates with insufficiently solid or weak surfaces.
• Strengthening the solidity of cementitious screeds with crumbling surfaces due to hydration faults or low cement content.
• Impregnation and priming of cement-bonded surfaces against dusting.
TECHNICAL CHARACTERISTICS
Prosfas is a low-viscosity mixture of water-soluble silicates capable of penetrating several centimeters into the substrate. Once dry, it increases the strength of cement-bonded substrates. Prosfas is ready to use and does not require dilution.
