    Safe way of testing for hydrogen?

    Definitely no smell. Just trying to establish if it’s corrosion or a leak.

    Safe way of testing for hydrogen?

    Thanks for the answers - I’m aware of the basic physics of lighting the hydrogen, but I was hoping for a safer alternative. I watched a YouTube video of someone attempting to safely ‘pop’ the hydrogen in an upturned kettle, but accidentally setting fire to their radiator!

    Safe way of testing for hydrogen?

    I have a radiator which regularly needs bleeding and I’d like to check whether the gas coming out is hydrogen. Is there a safe way of doing this (i.e. that doesn’t involve setting fire to it)?

    Zinsser Perma-White Peeling Off Woodwork

    Update - looking at the technical data sheet it says “Scrape-resistance over glossy surfaces develops in 5 to 7 days as Perma-White® cures.” So it looks like this is normal. It would certainly make me feel better if anyone has had personal experience though?

    Zinsser Perma-White Peeling Off Woodwork

    I bought Zinsser Perma White because I needed to paint a flat in a hurry and it advertises that it’s for both walls and woodwork, and is self-priming so it can be painted over old gloss/semi-gloss paints without a separate primer, saving a coat. I properly prepped/cleaned/sanded the first door...

    Accidentally used Dow 791 silicone in kitchen

    Ha ha :) I was thinking more that grease might stick to it more easily or something... anyway, I’m certainly not digging it out now!

    Accidentally used Dow 791 silicone in kitchen

    Phew! Will I suffer any ill effects? Will it go mouldy easier or will I have problems behind the cooker?

    Accidentally used Dow 791 silicone in kitchen

    I applied silicone around my new kitchen tiles yesterday, and this morning I realised I had accidentally used Dow Corning 791 instead of 785 (i.e. a weatherproofing sealant instead of a sanitary sealant). Is this a disaster?

    Dukka tape on Wedi board?

    I’ve got some Wedi backer board for tiling a kitchen Splashback, but I can’t get hold of Wedi Joint Reinforcement Tape as quickly as I’d like. I can get Dukka Waterproof Tape - I take it this would be a suitable alternative? Also, can I take straight over the tape without priming? Thanks

    Zinsser primers - do I also need undercoat?

    Thanks very much opps. I think I’ll just use 2 coats of cover stain this time so I can finish the tin. Next time I’ll buy a combined primer/undercoat.

    Zinsser primers - do I also need undercoat?

    Could I just do a second coat of the Cover Stain since I’ve already got it? In places where I’ve gone over twice it seems to hide pretty well, and it sands easily.

    Zinsser primers - do I also need undercoat?

    Thanks for the advice! Can you recommend a good undercoat to use under white satin water-based paint? All the undercoats I can find are combined primer-undercoats, and I’ve already done the primer!

    Zinsser primers - do I also need undercoat?

    I’m painting wooden doors, and my plan is two coats of water-based white satin on top of the Cover Stain.

    Zinsser primers - do I also need undercoat?

    Zinsser’s primers (BIN, 123 and Cover Stain) all say in their technical docs that they can be painted over with any water-based or solvent-based topcoat. But they never actually use the word “undercoat”; they only describe themselves as primers. I’ve already primed a new wooden door with...

    Paint lifting off window frame (interior)

    Thanks Ken. There are certainly some cracks in the external paint - I’ve been meaning to paint it! There’s no rot evident, thankfully, so any dampness is a recent thing. If I paint it now (externally), will I just be sealing in damp? Or does it dry out fairly quickly once the weather is warmer?
