- makes the substrate absorption uniform
- enhanced adhesion of renders
- reduces discolouration
- levels the curing process and drying of the applied render
PN 30 Silicone Base Coat
-
PN 30 Silicone Base Coat is used to strengthen the adhesion of silicone renders, decrease substrate absorption and allow the application of thin-layer renders. Reduces possibility of discolouration on the surfaces. Intended for exterior and interior application. Can be applied on substrates made of concrete, cement, cement and lime, gypsum, cardboard gypsum panels, particle boards, etc.
Technical data
Application temp.: between +10ºC and +25ºC Volumetric density: 1,55 g/cm3 ± 5% Drying time: to 3 hours Possibility to apply the render: 24 hours after priming Consumption: approx. 0.3 kg/m2 Container: 16kg, 8kg To be used before the render: TN 30, TSS 25 -
SUBSTRATE PREPARATION:
The substrate must be even, dry, solid, as well as dust, contamination, bacteria (fungi, mould, mosses) and chemicals free, etc. All contaminations must be washed under high water pressure. Old render and paint coatings of poor adhesion must be removed. Fill in any cracks with adhesives KS 10, KS 20, KU 11, KU 21 or KW 12 (max. up to 6.0 mm on one coating) or standard render mortar. It’s recommended to apply GN 30 Silicone Primer on substrates with poor load-bearing capacity, very absorptive and chalky (i.e. leaving dust traces after palm rubbing) in order to strengthen them. Fresh cement and cement-lime plasters have to be painted after min. 28 days, while concrete after min. 3 months. For thermal insulation systems the reinforced layer has to be seasoned for min. 3 days. All substrates must be stabilized regarding the moisture level and the hardening process must be completed.
INSTRUCTIONS FOR USE:
Mix the base coat carefully and apply with paintbrush. If necessary dilute it up to 5% with Silicone Primer GN 30. Base coat's drying time is approx. 3 hours, depending on the application conditions (the temperature, air humidity, substrate absorption, etc.). When applying the product under dark silicone renders, the paint must be tinted with pigments similar to the plaster's colour in order to avoid colour contrast in case of rubbing.
REMARKS / RECOMMENDATIONS:
Apply when the temperature is between +10ºC and +25ºC. Do not apply on heated substrate. During the render application and drying time avoid direct sun exposure, strong wind and rain. Protect the painted surface with foil or dense mesh till drying. The temperature during application and over the next 24 hours cannot be lower than +10ºC. After application wash the tools with water.
Works must be carried out in accordance with principle construction rules, as well as HSE standards and regulations. In case of using the product with other manufacturers’ products, the company shall not bear any responsibility.
The areas where the product was used or elements covered with the product must be ventilated until the odour vanishes completely. Only then can they be used.
