· Fills and seals gaps/cracks in most roofing applications.

· Bonds to: concrete, roofing felt, lead, zinc, steel and masonry.

· For bedding tiles, slates and flashing into position.

· Joint sealing on gutters and down pipes.

· Sticking down loose roofing felt.

· Joint sealing between corrugated asbestos cement and iron sheeting etc.

Limitations

· Do not use on glass

· Do not use on upvc

· Do not use internally

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 45^o 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.

· Incorporates polymer additives to improve adhesion

· Can be applied in wet conditions, even under heavy rain.

· Semi drying - remains permanently elastic beneath surface skin.

· High solids formulation - excellent gap filling properties without shrinkage.
