Caulks and sealant removal

[ash_scotland88]

Couple of questions.

 

1) is decorators caulk ok to use in the bathroom to fill in gaps of trims and facings? Obviously not in a wet area.

 

It'll be primed (123) then oil gloss'd

 

2) joiners (not plumber) put a sealant badly around our bathroom. It's also on (moisture) MDF panelling. What can do I do remove this safely?

 

It's a weird brown/grey sealant.

 

Plumber is also at a loss why they did, did it badly and did half a job on patches...

 

Hoping to remove it, get the boards painted, then reseal in a reasonable white.

Mechanically removing the worst of it is the 1st step, eg a Stanley blade / scraper, and a plastic removal tool (Amazon jobby) will get you so far. 
 

Then you’ll need to try Multisolve from CT1 which you spray on and leave for a while, then rub more into the sealant to remove it; it emulsifies silicone etc and cleans the remnants off pretty well ahead of new works.

 

Use a traditional cotton dish cloth for the cleaning phase.

 

Good luck, it’s a pig of a job.

New to me, thanks.

The new "snibbo" from reading the blurb.

Will it work on all brands and sealants?

Thanks, yeah I read about mechanical removing before hand.

 

Worried as it's a brand new bath (omnitub).

 

 

Caulk for rest of bathroom ok?

Where you’re painting, yes, but tbh I’d not go for oil based paints. Decorators caulk should only really be used for areas where paint meets paint, and nowhere else. 
 

If you need a more robust option, then clear / white CT1 sealant can be overpainted as it’s not a silicone, as silicone cannot be painted, but anything you’re thinking of painting gloss over should not be a sealant tbh.
 

There are some very good water based ‘gloss’ products, and they don’t yellow.

 

The bath will be fine, as long as you don’t go hard with the mechanical removal. Use the spray and time / effort there.

I’m afraid it’s suck it and see. If it works, as it does with silicone, it’s a total game changer and makes the job a doddle.
