AEROPRIM is a primer for adhesives on porous or rough substrates such as masonry, plaster, concrete, untreated wood, soft wood fibre panels, etc. AEROPRIM has a strong adhesive power creating an immediately high level of tackiness for use in difficult conditions (cold, humidity). Other applications are possible, after testing. Before any use, conduct tests to make sure that the product is suitable for the required use. To apply AEROPRIM, all the materials must be at ambient temperature before using the glue. The specifications refer to an optimal ambient temperature of 20°C and a relative humidity of 65%. Values may vary depending on materials and working conditions. The substrates to be glued must be flat, clean, dust-free and free from oil or grease. Remove any concrete and cement residue. Shake the glue before use.AEROPRIM IS RECOMMENDED WHEN USING AEROCONNECT SD20, AEROCONNECT HPV, AEROTAPE ADHESIVES AND WHEN FASTENING AEROLL SEALS ONTO TILES FOR APPLICATION ON ROUGH AND POROUS SUBSTRATES.
