Review: First class product - First class product and first class service
Review: Easy and everything you need in one kit - Really easy to apply, easy follow instructions. The tape is a bit of a pain to place and put on in the corners but that was expected. I like that it's blue too so you know where you've applied. Covered all 3 walls (from the bath to ceiling) and hasn't failed!

## Questions & Answers

**Q: I have two questions: 1. is this the large kit? and 2. can this be applied to new plaster?**
A: Hi, I bought this kit to tank a new walk in shower area. It should cover an area 7.5SqM and there is ample to do this. I suggest you use a roller rather than a brush and don't try to roll it out too far. The kit comes with a sealant which you brush on to the plaster or plasterboard (we put it straight onto plasterboard after giving two coats of the sealant). It should be OK on new plaster provided you use the liquid sealant first. An excellent product in my view.

**Q: Hi can this product be used onto existing tiles before filing over? All tiles are in tact and soundly stuck. Thanks.**
A: it does say to be used on pourous surfaces tles are not pourous, but you can use it on waterproof boards such as marmox ?I would call the manufacturerto be sure there is a primer from mapei that coats tiles and makes them able to take any product its about 38 quid for 2 half ltrs . I use it to prime tiles before levelling goes on

**Q: Hi, Please could you tell me if you think this would work under a wet room former  rather than tiles , Thanks**
A: this will waterproof just about anything if you go on everbuilds website they give information plus they have tech t phone up. The wet room former is fully waterproof in its own right ita built of watrproof materials and sealed and when waste goes in thats sealed as long as you dont screw it down which will beak any seal.  We stick them down like as though they were a big tile with rapid set flexible tile adhesive like Mapei. whata lot of people dont realise also if you using waterproof boards on walls you need flexible adhesive that you mix . tubbe dadhesive u only use on tiles 300x300 and lower in size . hope this answered your question

**Q: Hi, is the difference in kits one is 4.5l and one is 7.5l? What exactly do you get in the single kit?**
A: Hi Vijay 
From memory I ordered the 5lt pack which also had a1ltr primer and jointing tape this was for approx for 10 m2 of tile work which was applied to Gyproc Moisture resistant wall board and also sealed 2.5m2 of my 18mm plywood base of my shower tray and floor area as per instructions which you can view on you tube including the tape junctions to the wall board corner junctions and to the tray edge junctions where it meets the tiles works .I would suggest you work out all the areas that is to be sealed and by the buy the appropriate pack. 
Hope this helps.

### ⭐⭐⭐⭐⭐ Everbuild Aquaseal Wet Room System - Best on market
*by L***N on 17 February 2015*

Decided to buy the Everbuild Aquaseal Tanking kits for a wet room in a new-build extension, after reading-up on the product & looking at some You Tube videos. The products are very easy to apply, and there are clear instructions included in a leaflet within the tub, which also contains a small roller, & brush. The You Tube videos make it look SO very easy to apply, - and it really is easy! Remember to allow plenty of time for each coat of waterproof solution to dry properly before any second application. In cold weather, or in an unheated 'new-build' room, or perhaps an empty property, this may take a bit longer than when product is being applied in warm weather, or where product is being used in a heated house or flat. The only criticism I would have is that the brush enclosed with kit is of poor quality, & I know this has been raised by other customers, so I hope Everbuild take note!
