Whatever adhesive was used by the original builders is rock solid. It literally takes chunks of the block out to come out. But they’ve only dabbed big thick blobs everywhere like some are 50cm apart. There’s no pattern that I can see. What kind of adhesive did they use? It’s rock hard not sure...

On the current external side of my bathroom wall there is currently green plasterboard that was dot and dabbed. The thickness of the plasterboards look approximately 20mm. I’m ripping the plasterboards out from the blocks completely to replace it with 20mm xps backer boards. I’ve attached a...

I’m stripping out my bathroom currently. I believe that it currently has a form of tongue and groove chipboard with some sort of grey top layer so not sure what sort of floorboards it is. I’ve attached a closeup photo of the surface. Three questions: 1. All the floor boards have uniform join...

I need to screw 38x63mm CLS battens to the side of my joists to then lay plywood on it. I believe it’s recommended to also apply glue and screw it down. Wanted to know what kind of glue will work well with screwing the batten down?

I’m doing my bathroom and will have a concealed cistern. I’ve rippped my old one out and it was badly fitted and has been weeping for years but there is this sort of material on the floor that’s bone dry but deformed from how much water it’s sucked up. So got me thinking it’s a nice backup to...

On which one? The TRVs on all the radiators that I turned off are working because turning them to off has turned all those radiators off completely

I had a Baxi engineer come and change pressure relief valve on my combi boiler and also recharged the vessel. But later I noticed that two radiators downstairs were not heating up at all. They were working correctly before. I assumed it's an air lock somewhere. So i went upstairs and turned off...

I have a bathroom wall that’s about 2.3m wide and 2.3m high. There’s a small window in it (around 64cm x 92cm). I want to build a full stud wall in front of this wall to bring it further into the room, since I’ve got plenty of space. The idea is to create room for a wall-hung toilet, concealed...

So for the walls i dont need to worry about decoupling membrane?

Does anyone know if there is anywhere you can buy black colour 32mm waste pipe that is solvent cement type that comes preformed with a 90 degree bend? I don't need a it to be super long but just need a pre-formed 90 degree bend because of the location and access, ideally want to avoid joint at...

Ooopsi :) thanks. Sorry might be a dumb question but just want to be 100%. So if I wanted a 15mm copper pipe to insert directly to this connector itself for soldering on, then I need the 15mm female version? otherwise with the other connector it will be like have two ends of a 15mm pipe which...

Can anyone kindly tell me what the difference between these two connector below are? are the not the same sort of connector with a 1/2" male thread and the other end is solderable to a 15mm copper pipe? https://www.bes.co.uk/end-feed-male-adaptor-15mm-f-x-1-2-m-6775/...

Anyone know if the HMGL Brand TMV sold by BES is any good? I am trying to decide between either one of the following: HMGL 4 in 1 Thermostatic Mixing Valve TMV 2/3 - 15mm https://www.bes.co.uk/hmgl-4-in-1-thermostatic-mixing-valve-tmv-2-3-15mm-27599/ Inta Intamix Thermostatic Mixing Valve -...

To mount my wall outlet I i need to use the 1/2" ear elbow which from what I can see is what most of the 1/2" fixings seem to thread into. I've come across the following at ToolStation. Is this fitting a solder connection on the 15mm inlet...

I will try and draw something up and post later on. The original wall that it is attaching to is in this order Dot & Dab > Block > Gap > Bricks

I think maybe there’s been some confusion and maybe I have explained properly apologies for that. I am not having the toilet to the stud wall. I have a gerberit sigma steel metal frame as pictured. I’ve had these style system in my office for nearly 10 years and seems very robust. The...

I’m installing a wall-hung toilet frame and need to build a boxed-out stud wall for it. The toilet will sit under a bathroom window, so the new stud wall will only be about 125 cm high and will stick out from the existing wall around 20–25 cm. Because of the window, the studs can’t run all the...

Might sound like a silly question, but does anyone know of a tool that can potentially send some sort of wave and measure that on the other side to accurately determine where a drilled hole will come out of? I know measuring works but in some cases measuring is very awkward so a tool that does...

Very unhelpful thanks. Got it done
