Rated 5 out of 5 by from Wet Room Great product that does what yo need when waterproofing shower enclosures & bespoke details within the shower, such as recesses within a wall.

Rated 5 out of 5 by from Really good kit A really good kit if you are doing a bathroom or shower cubicle. Whatever you do make sure you wear gloves because this will not come off your hands unless you want to remove skin at the same time!

Rated 4 out of 5 by from MAPEI SHOWER WATERPROOFING KI Check the contents first if purchasing as on opening the tub found that the sealant container had broken and covered everything in the kit! No issues with Screwfix changing for a replacement however 1.5hrs wasted traveling through traffic to return. As a product I use this on all my shower installations (Some say belts and braces) A good product. A little overpriced as can be sourced cheaper

Rated 4 out of 5 by from Shower enclosure tanking kit Really great product if not a touch pricey! but worth every penny compared to the mayhem of water breach/stripping enclosure out. I found primer perfect over concrete board backing panel but over plaster etc would be tight going. Check out YouTube vids, lips onto acrylic/stone tray well - prepare well (mask 10mm lip off to tile deck, key up 120G, use acetone or isopropanol to clean - remask). Pre cut all bands and make sure the band adjacent to the tray is cut 9-10mm off the centre depression in the tape (struggle to bend accurately if just scrim removed). Be really careful what tile adhesive you use, ready mixed is 'air dry' which is rediculous mapei not pointing this out if tiling glazed ceramics for example .....nowhere for the moisture to escape and firm up (no rear suction) - you need cement based adhesive that is 'reaction cured' but not so forgiving if new to tiling .....Mapei Adesilex P9 Express is the nuts, much longer open time than normal cement based adhesives around 60 minutes and can grout same day if you've got the energy!

What can I use to clean the primer off a shower tray?

The tray is the MIRA FLIGHT SAFE RECTANGULAR SHOWER TRAY WHITE 1000 X 800 X 40MM (7818X) which is Acrylic-Capped Stone Resin.

Aqua panel clarification

To clarify, do I apply the waterproofing liquid and tape to bare unprimed Aqua panel ?
Asked by: Brdr
Mapei Shower Waterproofing Kit can be applied directly to a cement based tile backer board, providing the surface is contamination free.

Do I prime Aqua panel before applying this?

Aqua panel says to prime before tiling, will this waterproofing act as a primer or should I prime first and then apply the waterproofing? I’m going for belt and braces ( ie Aqua panel and waterproofing) as I’m putting a niche in the shower.
Asked by: Brdr
You will not need to use the primer supplied in this kit before applying the waterproofing membrane to Aquapanel boards.

Can you use it on old tiles in bathroom before putting new ones on

Asked by: Dee1878
Mapei Shower Waterproofing Kit can be used over existing tiles providing they are contamination free. In most cases it is recommended to abrade the surface.
