    Primer on green slab before decoupling membrane

    Hi all, I want to lay 600x400mm limestone floor tiles on a newly laid concrete slab. It's laid flat so no need for screed. The room needs to be used asap so I don't have time to wait for the usual 28+ days before tiling. Therefore I'm going to use 1) Decoupling membrane on S2 adhesive 2) Stone...

    Chimney air brick inside or out?

    Hi, We have a disused chimney which has suffered with damp problems caused by a lack of ventilation. The top is now ventilated via a c-cap but I believe it's also good practice to ventilate the bottom. This would actually be at 1st floor level as on the ground floor there's an alcove over...

    What's the best way to cap this chimney?

    Hi, I'm removing a old flue from a chimney that's no longer used. The other issue is that the current cowl let's water into the flue during heavy rain. As per the photo there's no pot only the thing that holds the flue. I've removed some of the mortar which had all crumbled anyway. What would...

    Allowing an old wall to breathe without using lime plaster

    If you've got an old house, or if you simply want to avoid damp walls then the mantra is Breathability. Which translates as lime plaster on the internal side of exterior walls. BUT - it's hard to get hold off, eye wateringly expensive, difficult to use, and if you can't DIY it then suitable...

    Any white oil based paints that don't yellow these days?

    Every oil based paint I've used since the new EU regs a few years back have turned a nasty cream after a few months of sunlight exposure. Taken to using acrylic water based paint for all interior wood which is great but I've now got to do some exterior painting and would normally have used...

    How best to use batons for exterior render?

    I'm a bit confused r.e. the use of batons to ensure an even finish as have read conflicting information. I presume this is the correct order: 1) Fix 19mm thick batons at 900mm spacing 2) Apply scratch coat to estimated 10mm thickness 3) Apply top coat and then use straight edge to level against...

    How does this flat roof structure look?

    Thanks for the info. Presumably this design with a capping board is for open cornice? If I used something like this is it acceptable to just stick this to the fascia, with the extra strength coming from the sub fascia board and the rain deflection coming from the projection and built in angle?

    Orangery style 3 sided extension - you're correct - and plan is for discharge into a hopper with no gutter.

    How does this flat roof structure look?

    I'm happy with the construction of the actual deck but there's a couple of thing I would like to check: 1) The fascia board arrangement - specifically is there any advantage to bringing the board out with batons to create a cavity behind it. It would be simplest to just screw it to the end...

    Does this drainage system look ok?

    I think with a 90 degree bend and a connection to an old system of an uncertain course it's probably best This is a new installation at the back of the house which will convert an old gully to an underground system so no existing vent pipe or AAV. Having read a bit more the issue of the AAV...
