Rated 5 out of 5 by from Sticks to everything even me! Tried a lot of different sealants in my job as DIY'er Electrician/Plumber to a successful Boarding Cattery. The manufacturer's seals started failing after 3 years up to 41/2 years on the UPVc Pen units. Over the last 2 years I've been doing a WHICH type test of various sealant brands. Nightmare. Different sealant in 10 of the busiest units/suites. Which dries fastest, which fumes the cats to distraction, which one prevents wee pees from lifting the seals, which looks the best and of course which one has stood the test of time. On average over a year the 44 units have to be cleaned with a high strength sanitiser and dirt lifting concentrate once every 4 days with a rotary mop and bucket. The only seal still going is SIKA PLASTIX - it has not curled or lifted and looks the same as the day it was put down. I can't thank you guys at SIKA enough although you appear to have put yourself out of business - once all units are sealed I don't need you any more - so really - thanks a lot.

Rated 4 out of 5 by from Conservatory Repair I needed a sealant to repair a joint in a conservatory roof joint - this did the job well. It was important that the sealant did not react with uPVC, the rubber seal or the polycarbonate roofing sheet (many other products are not compatible), but this Sika Plastix sealant is neutral curing so no nasty reaction with other materials. This sealant has good adhesive properties so no problem applying this to other materials. I would recommend this product.
