Thanks for these really helpful responses. Just to say that the variation in floor level will require adhesive thickness of between 3-4mm and 12mm. We could take the higher parts down a bit - these are near an entrance door so need to think of door clearance and ability to put a mat there in...

Yeah the primer was done correctly. On the first part anyway. But the first screed layer was covered with a new layer after an hour or two - so not cured - and wasn't primed. As far as I know, you're supposed to let a first layer fully cure, then prime it, then start a new layer on top. If we...

Underlay and laminate. The surface right now is a bit of a mess. And has added unevenness in levels. Assuming it is structurally sound (I guess we could have a good stamp over it on Monday to see), I'm thinking we hire a floor grinder, even it all out, see how intact the surface is and then...

Prefer to just use tile adhesive.

So basically, after the photos above, he sprayed water on it and smoothed off to get rid of big holes and spiked surface. I don't know how effectively this will have removed holes below surface. He has then poured again over the top of it all about an hour later. Today it looks like the...

Hello, We are tiling floor and walls using 300 x 600 (9mm thick) tiles. The floors are bare concrete and the walls are 12.5mm plasterboard with a paper covering. I'd be grateful for advice: A) do we need to use primer on the floors and walls? If so, which type? Gaps between plasterboard have...

Thanks. I suggested just taking it up whilst it was still tacky. Better than trying to do it tomorrow when it is rock hard. We will have to see tomorrow if it has actually worked or not as a surface. He sprayed water over it and smoothed it all out, mostly. There are bound to be some flakey...

Used Benfer 2-50fl on a new concrete floor primed with SBR. Greatest depth around 15mm. Builder who has used it is experienced and used the product before, albeit less depth. He measured out correct amount of water. Doors closed. Not particularly warm in the room. Anyway, he has run his spiked...

Yes, although it will connect to the public mains so I suppose has to be in accordance with regulations...

Hi everyone, I am having a new water main installed at my property tomorrow - 25mm blue pipe buried in a 750mm deep trench. The idea is to put builders sand at the bottom and just on top of the water pipe as bedding although the installer is somewhat reluctant to do this saying it isn't really...

Hello, I'm having new windows and doors fitted into a new extension next week. The bricks are Staffordshire multi rustics. I've asked the window fitting company to use brown silicone as my previous experience suggests that window fitters often leave a nasty silicone finish on these rough bricks...

Can the GRP valley just be attached to rafters with only felt under it? This is what the roofer for my house has done. Which might explain why it is like a banana. No ply under it.

In my experience!

Thanks for this. So just to be clear: the valley has a central ridge which is the highest point. There are then two lower ridges either side of the central ridge. Are you saying that the tops of the tile battens should be flush with these lower side ridges? Such that the tiles would sit evenly...

Yes, however, I need input from building experts. Are roofers idiots? Of course not. However, I think the advice I get here might be more detailed.

What do you mean "flush"? The valley tray has different ribbed parts. Do you mean that the ribs at the sides of the valley tray should be flush with the rafter tops? Can I have the height different on either side?

Since roofers seem to clock off at 2pm and are probably all in bed, and I need answers quite urgently, I'm posting this here. It is a building related issue anyway as touches on different factors. Hello, Where the roofs of my existing house and extension meet at the GRP ribbed valley tray, the...

Maybe, although a lead valley in this case would be higher on one side than the other and I don't want to be getting pointing done in future. And funnily enough, I can't do a great deal with your advice now short of ripping the lot off and starting again, so if anybody has any thoughts on how to...
