Although product forms a surface skin, Roof & Gutter will always be tacky to the touch. Do not use in applications where physical surface contact is likely.

Surface Preparation
The surfaces to be must be clean, and free from dust, grease and other contaminants. New concrete or mortar should be allowed adequate time to dry and mature. May be applied to wet surfaces.

Application
For lap joints, apply sufficient sealant to bridge the gap and press surfaces together while still tacky leaving a minimum 2 mm sealant film.
Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut at an angle of 45o with an opening slightly larger than the gap to be sealed. Apply using a standard sealant gun. Best results will be obtained by keeping an even pressure on the trigger and keeping the gun at a constant angle to the surface being sealed. To ensure a proper bond, always smooth the sealant down with a spatula or piece of wood wetted with linseed oil or white spirits. An improved joint appearance can be achieved by placing masking tape to both sides of the joint, removing within 5 minutes of application.
When using as an adhesive, press surfaces together, pull apart and wait for approx. 10 minutes until sealant becomes tacky., then press together and apply even pressure.
Clean tools in turps or white spirits.
