    Tips for painting old wardrobe

    I did something similar a few years ago. Definitely do a light sand and then use a primer. I have had no issues with the new paint scratching off etc

    How to join up old DPM to new DPC.

    Could I get your thoughts? Two years ago, a contractor completed phase 1 of my renovation, creating a passage to an annex. This resulted with a 7cm step down. I now plan to raise the floor level but noticed efflorescence on the concrete at the patio doors. Can I use a Bituthene layer to close...

    Efflorescence on floor - DPC/DPM breach

    I looked on the planning portal and that extension was registered in 2011... The exterior has air bricks which indicates a beam and block floor; so I'd say there would be insulation in that case? The UFH guy did ask me all this before he committed to quoting for an in-screed system. He seemed...

    Efflorescence on floor - DPC/DPM breach

    Afternoon @^woody^ . I've gone back through my photos again and yes you're right to question the slab. I found a photo of that window area just after they were removed and the extension foundations were being dug. I've pieced together a better diagram of what think it is and labelled a few...

    Efflorescence on floor - DPC/DPM breach

    hi! Firstly, thank u for taking the time to respond. There’s no visible moisture under that DPC. However I would say that wood CLS is damp feeling. I don’t know if there’s a cavity between it and the outer skin. From the photos I have I think the old white sliding doors were sitting directly...

    Efflorescence on floor - DPC/DPM breach

    Had some building work done last year include new French doors. Have been saving up some more £££ to finish the room. This winter I’ve noticed a patch of efflorescence. It didn’t happen last year. Seems a bit odd. Are there any immediate actions I should take? The second photo is under that...
