Spray Primer

The blaugelb Spray Primer is an adhesive agent based on a rubber dispersion for preparing the substrates for bonding the fleece-backed foils. It has an excellent adhesion-enhancing effect on standard construction substrates. The use of the blaugelb Spray Primer is advantageous in order to ensure proper bonding even on difficult substrates. Due to its short flash-off time, further processing can be carried out quickly.

The blaugelb Spray Primer also acts as a spray adhesive. During processing it shows very little “overspray” (unwanted fogging). The spray jet is focused, but wide enough to wet the surfaces. The spray jet can be individually adjusted with the variable spray head. The blaugelb Spray Primer is suitable for use in almost all seasons. It can also be used at slight negative temperatures (down to -5 °C).

The blaugelb Spray Primer is ready to use and can be processed right away. It is ideal for use on façade parts and almost all standard construction substrates, for internal and external sealing of windows and doors. Ensure good ventilation during processing.

Highly suited for use on walls, soffits, floor slabs, foundations, balconies, underground car parks, terraces. Suitable for mineral, porous, absorbent, non-absorbent, sanding substrates, plastics, wood, metals.

Note: Substrates containing bitumen and plasticisers can reduce the adhesive strength of the blaugelb Spray Primer, in the worst case just a few weeks after application.
