Dosage Information
  • For most applications a dilution of 1:3 - 1:1 of the product in demineralized water is recommended. The amount of Protectosil® WS 340 PLUS to be applied and the concentration to be used are highly depending on the absorbancy of the substrate and the desired penetration depth.
  • Very absorbent substrates may require up to 500 – 1000 g/m2 Protectosil® WS 340 PLUS (1:3 dilution in water).
  • Gently stir the product before preparing the dilution. Protectosil® WS 340 PLUS should be applied by wet-on-wet flow coating to the saturation point. The solution should be applied in 2 - 3 coats without drying between the coats as the water repellent effect of Protectosil® WS 340 PLUS can develop within minutes. On vertical surfaces the solution should run down in the form of a clearly visible descending wet curtain. This is achieved by allowing the solution to flow against the surface of the building material without pressure.

Storage & Handling

Storage Information
  • Substrates to be treated should be dry and clean. Acceptable surface cleaning methods include sandblasting and water blasting.
  • Most liquid delivery devices (e.g. airless spraying equipment) are suitable. The material should not be atomized or applied with a brush.
  • Due to its high water content Protectosil® WS 340 PLUS is frost-sensitive and should therefore not be used at temperatures below 0 °C. The ideal temperature range for the application is +5 °C to +40 °C.
  • Protectosil® WS 340 PLUS should be stored at temperatures between +3°C and +40°C.
