Does what it ways on the tinReviewed by Richenda on 27 Nov 2020

Needed a quality adhesive to bond the silicone flashing for our garden wood burning stove chimney going through a corrugated polycarbonate roof. Only on the actual Deks website did it clearly state the adhesive can be used for a plastic roof as most information only mentions metal so it was a bit precarious. However plunged in cut a big hole in the roof and fitted the Silicone flashing with the adhesive. It formed a great bond instantly and was super tacky but easy to use and apply. The bond is completely water tight as the adhesive apparently reacts with the dampness in the air and cures to a flexible permanent join. So really pleased with the product. Does what it says on the tin. Also the service from Roof Giant was 1st class. The adhesive arrived with the stated 2 working days where on most sites it was saying two weeks for the same product. So really pleased and will not hesitate to use Roof Giant again for similar requirements. Definitely a company you can trust to deliver what they say.
