Blaugelb Spray Primer

Blaugelb Spray Primer is a rubber-dispersion adhesion promoter that preps construction substrates for bonding Blaugelb fleece-backed sealing foils.

What it does

It sprays onto porous, dusty, or otherwise difficult substrates and creates a stable surface that the fleece-backed foil can bond to reliably. Short flash-off time keeps the install moving.

When and where to use it

• Pre-treatment for porous, absorbent, or non-absorbent substrates
• Sanding substrates, plastics, wood, metals
• Mineral substrates (concrete, brick, masonry)
• Wherever the standard self-adhesive layer of Blaugelb foils needs help bonding

Key benefits

• Excellent adhesion-enhancing effect on standard construction substrates
• Short flash-off time — fast next-step processing
• Spray application — fast, even coverage
• Compatible with the full Blaugelb sealing-foil line
