Hi folks! First time poster here
I'm doing a DIY bathroom reno and just yanked the old medicine cabinet off the wall... I expected to see exposed bricks but there's this concretey grey stuff on top of the bricks (that I assume is the same adhesive behind the tiles themselves?).
I need to mount the new medicine cabinet in this spot but unsure what to do with this section, so my question is do I need to seal/paint/fill in the bricks and old adhesive first?
The new cabinet is larger than the hole left by the old one, see the third image below with the outline of where the new one will sit.
Massive thanks in advance for any advice!
Great to see you make your first post. Thanks for joining in the discussion. We are looking forward to seeing how your bathroom renovation progresses. Maybe you could share some before and after images in a new discussion?
I'm sure Workshop members will be happy to help with your question about whether you need to do any preparation before mounting the cabinet. I might help if you provide a little more information, though. For example, I see that there's a shower next to the cabinet. Do you expect any water to hit it? Is there any sign of any previous issues that you might need to address?
Welcome to the community,
Welcome @dannyrus.The good news is, with the new cabinet being bigger than original, you don't have the pesky job of patching/smoothing for a clean finish around the cabinet.
I agree with @Simon. I'd fill any actual gaps/holes in the cement/bricks to prevent moisture build up then seal over it - two coats. Once the new cabinet is on the wall, seal the edges with a wet area silicone colour to match your cabinet/wall (or just go with clear) and you should be done.
Of course you can!
Simplest way is usually to just use some lengths of timber (offcuts) or books, bricks, etc. Just remember to protect your basin/benchtop first!
