Brand New Trade Quality Product
A cold applied, heavy-duty felt adhesive.
A solventborne, black bituminous adhesive. It provides a firm but flexible bond between 5o C and 50o C which hardens and softens with changes of temperature.
Bond It FELT ADHESIVE is a cold applied adhesive for bonding bituminous roofing felts to asphalt, felt, metal, wood and concrete. It can also be used for bonding mineral chippings to bituminous surfaces. It may not be used over tar based products.
Preparation All surfaces must be clean, dry and free from grease, oil and any loose material. Remove any organic growth using a fungicidal wash such as Mould Stop.Dusty and porous surfaces should be primed with BITUMEN PRIMER. Where possible, felt to be laid should be cut to size and positioned for 24 hours to assist application. FELT ADHESIVE can also be thinned with 10% white spirit and be used as a priming coat or gritting solution. To avoid thickening in cold weather, store FELT ADHESIVE overnight in a warm room prior to use.
Application Apply FELT ADHESIVE to the roof area with a mop, squeegee or stiff brush. Do not exceed guideline coverage rates. Allow the adhesive to become tacky to touch (typically 15 minutes to 1 hour) then place the roofing felt into position. The felt should be lapped: side laps minimum 75mm and end laps minimum 150mm, and the laps sealed with FELT ADHESIVE. When laying the felt it is important to ensure that no air is trapped underneath, particularly when laid over a previous layer of felt or other waterproof coating. Roll with a 15Kg roller or thoroughly brush with a stiffbroom until good overall contact is established between felt and adhesive, especially at the laps. NB. If felt is applied too soon, the drying time of the adhesive will be extended and the adhesive may ooze out. When felting upstands, adhesive should be applied to both adhesive and felt.
Timber Roofs: Lay the first layer of felt laid down in accordance with BS Code of Practice 144: Part 3 and bond subsequent layers with FELT ADHESIVE.
Lap Adhesive: FELT ADHESIVE can be used to bond laps on single layer applications Ensure area to form lap is completely coated with adhesive and press firmly to expel air when tacky. The lap should then be nailed with galvanised clout head nails to secure bond. Gritting: FELT ADHESIVE can be used as a gritting solution. Be sure to overgrit and tread well in or preferably roll. Drying Time Drying will vary depending on weather conditions and time allowed for adhesive to develop a tack. 24 to 48 hours is typical. However, heavy applications will result in extended drying times.
