PROMASEAL® Intumescent Acrylic Sealant Grey

Tested to  BS 476: Part 20

Also tested to EN 1366-3 and EN 1366-4

PROMASEAL® Sealants will adhere to most construction materials. Very porous surfaces may need to be wetted with clean water to prevent too rapid drying of the sealant before proper cure.  If in doubt, the sealant should be applied to a small length of joint and examined, or the Promat Technical Services Department should be contacted.

All surfaces should be clean, dry, oil, dust and grease-free and loose paint should be removed from steel. 

It is advisable to tool the sealant firmly against the joint faces and the sealant can be dressed off with a wetted trowel. Where there is a fire risk on both sides of the substrate, the sealant should be installed on both sides.

Can be overpainted after approximately 48 hours (dependent on ambient conditions). Consideration should be given to the flexibility of the finished painted coat when movement is expected.
