Bellseal Fix’n’Seal is simple to fit, for no leaks.

Bellseal Fix 'n Seal is designed to fix any bathroom appliance, bath, shower tray, basin, or kitchen worktop securely and permanently to the wall. It is also suitable for use in wetrooms.

It acts as a permanent seal even when edge sealants fail.

It is flexible enough to allow the natural movement of the bath or shower tray in use without cracking, and strong enough to stay fixed to the wall.

No additional sealants, no mess.

Water getting between bath or shower tray and wall can cause serious damage, even before the problem becomes obvious. It contributes to the deterioration of plaster and timbers, and hidden behind tiles can be causing a significant problem before it becomes visible.

Water finds its own course, so if there are adjoining properties (for example a flat below) the problem can become even more serious, resulting in the need for expensive repairs, high insurance claims and increased premiums. Not to mention the inconvenience.

Traditional sealants can be tricky and messy to use properly, and will ‘cure’ (drying and cracking) over time, eventually becoming less watertight. And many require the use of additional screws and brackets to ensure baths, sinks and shower trays stay watertight against the wall, adding to cost of installation.

A smart sealant product loved by both trade professionals and DIY customers.

That’s why Bellseal have invested heavily in developing Fix 'n Seal, a smart sealant product loved by both trade professionals and DIY customers.

The two-part system consists of a black thermoplastic DPC membrane (the same material which is used when damp-proofing houses), and a white heavy-duty butyl membrane.

It sticks firmly to virtually any surface, with no need for primers, screws, brackets or additional products. It even provides instant grip to newly dried plaster.

“I bought my first double-sided Bellseal membrane in 2018 and it’s been bombproof since then. It was easy to fit and makes the whole job look so much better than additional trims or extra thick sealant.

We had major problems with leaks in our bathroom and it’s totally sorted it. I’m now converting a van to a camper and this new seal will ensure that it’s leakproof. When we renovate the en-suite, we’ll definitely order another. It’s a no brainier.”

“Just completed the shower and would like to say what a wonderful product Bellseal is.

I had been searching for some time for something that would seal around the edge of a flat shower tray, but with little success. The only other products I found looked inferior to yours and didn’t inspire me with any confidence.

Bellseal does exactly what it says: bonds to the tray very easily and then to the wall. I also used the Bellseal single side version to seal the corner where the two walls meet.

Both of these are now fitted and 100% leak free. Very easy to tile over giving a professional finish.

Thank you for all your help and the very quick delivery.”

“I was fitting a shower in my granddaughter’s house and wanted a quick and simple way of fixing and sealing the shower tray to the walls.

I saw your promotional video and thought this product was the best for the job. I was not disappointed. Delivery as promised, easy to follow instructions, easy to use product and it does what it says on the tin.

The shower tray is now fitted and sealed and it only took me 15 minutes to do the job.

Thank you Bellseal. I would highly recommend your product and would use again in the future.”
