As is mentioned in the articles linked to above, tanking essentially waterproofs the walls behind tiles in wet areas such as shower enclosures to ensure long lasting tile installations.
- Convenient (ONE STOP SHOP) Everything needed is sold in 1 tub which can be bought online and delivered to you door.
- Cheap – around £50 per kit which is enough for 1-2 whole shower enclosures (depending on the kit bought)
- Can be easily applied to complex shapes if required
- Permanently flexible
- Easy to apply with an old paintbrush and pair of scissors
- Produces a seamless membrane
- Matting joint tape normally sold separately
- Adhesive sold separately – must be a flexible powdered adhesive (not tubbed)
- Less convenient (arguably) as you probably need to visit a local tile supplies retailer
- No leftovers to do other showers as with the other kit
- Care needs to be taken to ensure no buildup of adhesive under the matting leading to non flat walls
- Difficult to apply to complicated shapes.
- Non seamless membrane if numerous sheets are lapped together
It depends on you priorities.
With me, if I need to tank and tile a shower enclosure in a single day, I will use the waterproof matting system to allow me to get on with it and not wait for anything to dry.
I can use the same flexible, rapid set adhesive to apply the matting and then immediately apply the tiles on top of the matting.
Otherwise I will use the all in one tanking kit, and this always allows me excess primer, tape & waterproof paint to do further shower tanking installations making it more cost effective for me
Also, more complicated shapes can be done more easily – I did the installation above with matting and really wish I hadn’t:
