Sealing Tile Backer Board Joints ~ Roger's Tips

Abacus Bathrooms Elements Board

Aquaseal Wet Room Waterproof Tanking Membrane

CT1 Multi-Purpose Sealant & Adhesive

_______________________________

Roger is on familiar ground. He loves a bit of Elements Board and knows just what to do with it.

Our message from Michael:

I have installed tile backer boards but am confused about sealing the joints. I was advised to use a tile adhesive between where the boards join and then a tanking kit with tape to seal the joints. Is this correct, or should I be using different products? Any help is greatly appreciated. Best Regards, Mike

I used this stuff in my bathroom and kitchen after watching Roger’s bathroom installation vids. Amazing product, lightweight, easy to cut, rigid, and completely watertight. Not particularly expensive either tbh. Battening out behind it also allowed me to get everything perfectly square in a 150 year old house. Handy when fitting kitchen units and baths etc.

Ah!! It's me, thank you, Roger. All done, taped, tanked, job completed. Your advice has been really useful and the videos help massively.

That’s exactly what I do …Polymer based polymeric adhesive between the joints . Have done for a good few years now.

I used Jackoboard, like most manufacturers they have plenty of online advice on fitting methods, suitability of application for the various thicknesses of board etc, though sometimes it can take a while to locate.
like Roger suggested, in wet areas like the shower, glue the joints, then waterproof tape over the top fixed with brush on sealant/adhesive, you can also use the polymer adhesive/sealant over the top of the washers or on any board damage, then waterproof tape and brush on sealant adhesive, neoprene gaskets with brush on sealant/adhesive for any pentrations through the board such as shower valve/ handspray/shower head
Any penetrations for screw fixings on final fix, eg for the shower enclosure, I flooded the holes with either silicone or the polymer adhesive just before fitting.

I've been following your renovation projects and appreciate the insights you share. I recently conducted a detailed exploration into the safety and installation practices concerning foam core backer boards, specifically focusing on the critical role of wood blocking for secure grab bar installations. Our findings highlight the potential risks and structural integrity issues that can arise from omitting wood blocking, even with the most reliable materials and techniques.

Given the importance of safety and durability in renovations, I thought this information could be beneficial to your projects and audience. Incorporating wood blocking can significantly enhance the strength and safety of grab bar installations, a detail that's often overlooked.

I'd be happy to share our findings and discuss further. Keep up the great work, and thank you for sharing your knowledge with the community!

I used wedi board (same thing) back in 2006 when i did a wet room with an open shower. Never had a problem despite using the shower twice a year. Seriously though, if its done properly it should last almost indefinitely. I used the neoprene tape on the joints but things have moved on since then.

Personally with the backer I would follow Roger - I gap them with 3mm glazing packers - silicone or CT1 or OB1 the joints then scrim tape for a 100% wet room. Can even silicone the corners b4 scrimping. Never had a problem yet

[alansmith]

love the abacus board.couple of things, can be difficult to drill to fix enclosure etc if you hit a metal fixing washer.Also if your tiles are thin sometimes you have trouble getting a good fixing

[billeltham]

I would like all the latest info on roofs/solar panels and their integration, and I would like to see Roger on a roof that demonstrates a good recent example. Oh and thanks once more for the invaluable guidance - it's my goto manual!

[edmundhodgson]

Love this board, certainly helps the acoustic as well

Broadcast from my House, Thank You very Much! 😊

I'd like to see Roger in scenes from major historical events, like a Forrest Gump, or Good Omens.
Roger giving plumbing advice in a Roman spa, or bricklaying advice at the Pyramids, electrical advice in Frankenstein's lab.
(What do you mean Frankenstein wasn't a historical event?)

[baldyslapnut.]

Use plastic washers not SS, secondary fixings will penetrate easier. Put your offcuts at the outer edge so there are fewer tape joints in the wetter corners.

[imaginitivity]

It looks like quite a lot of additional work with those small panels though and more joints to worry about. I've used 8x4 cement based 'plasterboard' sheets in these applications. Heavy buggers, but bomb proof I think

[loadzofhobbies]

I use the propriety expanding adhesive on the joints thats made by the same manufacturer. Then use a knife to cut back the glue flush with a Stanley blade.

Next broadcast should be from a zen garden but only if Rogers getting irate about heat pumps or the like for the contrast.

[burwoodbuild]

Abacus Elements all the way… I wouldn’t use anything else now! 🔥😎

[timbobau]

Great advice.
Maybe the next video should be at number 10 Downing Street? That will give the correct level of authority.

[williamsdaduk]

the sts boards you get from wickes say to use their own foaming adhesive in the joints ... its horrible stuff foams out of the joint causing a ridge you then have to try and cut off ... damaging the board in the process

[giogio]

Ok...I've just been doing a shower cubicle and have used these for the first time...tbh i don't see the point .I've done my bathroom in plasterboard, tiled straight onto the board 15 years and no problem so far..if you do get a leak even on backer board the tiles still gonna come off.correct me if im wrong Rodger.
