I recently did a flat roof in fibreglass and am very happy with the result. I now want to create a wet area in my bathroom which is below ground, the floor is screeded. Can anyone see any problems with me just fibreglassing over the screed?

Thanks

Brendan.

Needless to say I am not worried about how it looks, just that it works.

Find an active boating group. There are a lot of boats made with various
fibres and resins. You should be able to get hints on how to make it
properly waterproof and not too slippery.

I presume you'd be better off resinning it, fibreglass not required. It does mean any damp coming up will be concentrated at the edges, with the risk of causing damp brickwork. Bitumen does the same job cheaper.

I've removed the skirting and the bottom row of tiles and am planning to return the fibreglass up the walls a bit, hopefully the glass mat will give the resin something to cling to as well as providing a textured not very slippery surface. The whole place is damp already.

I completely agree about wet areas normally but this is to allow washing with a shower hose in a sitting position. I will be prepared with squeegees and towels for mopping up.

IMHO wet rooms/areas in this country without underfloor heating
are a complete waste of time and a royal pita.

I stayed in a holiday cottage where all 3 bathrooms had wet shower
areas adjacent to the room entrances. One even had a wet area
shower immediately behind the door in!
Result was that all subsequent bathroom/toilet users had to paddle
through the wet tiled areas to get to the other parts of the
bathroom. ****! get some shower screens!

ISTR resin on glassfibre leaving sharp bits sticking out here & there, but memory probably rusty on that.

If you want to have grip you'd do better with a light sprinkle of fine sand than using glass. Concrete doesn't need the glass.

I'm glad you said "without UFH"... That's a key factor IMO. The Forest
Holidays (basically Forestry Commission) Log cabins in the Forest of
Dean have wet rooms and UFH and they dry in a matter of 10-15 minutes.
Plus the shower at the other end from the door. The setup you describe
sounds very ill thought out.

If it's damp,the last thing you want to be doing is covering it up.

Boats tend to be made in moulds though so I'm not sure you could do this on
a floor. also and I'm reaching back in memory here, there was something
about its pliability if it was not supported properly or under strain
causing cracking, but it was a long time ago, and maybe materials have
improved. It certainly pongs though.

Thank you all.
That's the one thing I didn't think of, it's going to stink and it's an en-suite.
Too late now, I will just have to take measures.
