Sika Sika Plastix uPVC Sealant White 300ml is rated 4.7 out of 5 by 21.
Rated 2 out of 5 by from Sealant cracked after applying Bought the more expensive brand of sealant to replace a cracked line of silicone on our conservatory where it joins the house (thinking I was buying a quality product!) I raked out all the old silicone and cleaned the surface properly yet only days after application this new stuff is full of cracks!? I've never seen this before, I've used sealants numerous times and I wouldn't be surprised if it was caused by movement yet there is no obvious movent in the conservatory at all (certainly nothing that would cause that much damage in such a short space of time). I'm puzzled really and annoyed!

Rated 5 out of 5 by from Excellent bond strength I have used many Low Modulus mastics for bonding shower panels and Acrylic sheets and results were very hit and miss with others, And any call back on defective work doesn’t reflect well on my business and I’m unlikely to be recommended to others by the customer But since using this product the time taken up on call backs has diminished Entirely.

Rated 5 out of 5 by from Window sealant Previous sealed around my window using silicone which over time dries and cracked causing the surround to leak again. This stuff feels better from the start and as soon as I finished sealing the window we had a downpour but with no leaks, fabulous stuff and highly recommend.staff at Bridgend store were great too.
