Let’s take a quick look at answering the frequently asked question: can decorators caulk be used around a bath?
DO NOT under any circumstances use decorators caulk as a sealant. Based purely on price, it may seem like an attractive idea to use it around a bath, however this is never a good idea.
In simplistic terms acrylic caulks are not flexible enough to keep a bath or shower water tight. This means that the caulk will quickly crack once weight is applied to the bath or shower tray, so you’ll quickly be spending even more money on a repair.
In summary here are the reasons why the answer is no:
- Caulk is not anywhere near flexible enough
- It dries with a very dull finish
- Decorators caulk is not resistant to mould
- Finished caulk surfaces are not smooth or glossy like dedicated bathroom sealants
- Very limited choice of colours.
Beware of Caulk Language Differences
Mistakes using decorators caulk around a bath sometimes happen because of the subtle differences between British and US English. In some countries like the United States, the word “caulk” or “caulking” is a generic term used to describe a sealant.
In contrast, the UK uses “caulk” to refer to a low-cost gap filler, not a sealant. Unfortunately, UK readers often encounter US-based help and advice articles, which can lead to costly mistakes.
Silicone Sealant Alternatives For Sealing Baths
If you’re looking for an alternative to silicone sealant, then we recommend you can try a modified silicone for sealant a bath. These are very similar to silicone and in most cases, offer better all round performance. Without the strong vinigar (acetic acid) smell that you get with certain types of acetoxy silicone sealants.
