Using it

Directions: the joint surface must be hard, clean and free of dust and grease. Mask the joint edges with tape for a clean finish. Cut the cartridge at the top and screw on a nozzle cut to the joint width. Apply the sealant as evenly as possible.

If work is interrupted, release the gun handle and pull the piston back. Level the sealant with an appropriate instrument or a well soaped finger, and remove the masking tape before the sealant starts to harden.

Joint limits: width 6mm to 20mm, depth up to 20mm. The sealant must not grip the bottom of the joint, so use polyethylene or polyurethane foam backing. Apply between 5°C and 30°C.

Storage and handling

Store in the original, sealed containers in a cool, dry, well-ventilated place.

Limits and safety

Formaldehyde may be evolved during curing or decomposition, which is a skin sensitiser and classified as a confirmed human carcinogen (IARC Group 1). Acetic acid may also be evolved, which is a respiratory irritant. Over-exposure is not anticipated under normal conditions of use. Read the safety data sheet before use.
