help with silicone around bath etc

steveo3002

right ive sealed up the gap around the bath /tiles with proper bathroom mould resistant silicone

say 4 months on and its lifting /peeling on the edges where you wipe over it with a cloth , and theres the odd black spot

ive redone it several times and its getting a chore

any ideas on doing a job that lasts well? its a plastic bath against tiles

Should last longer than 4 months, in fact more than 4 years!!

Sorry but will have to start with the obvious questions
Did you get off all the old sealant?
Was the bath/tiles clean and dry ?
Did you fill the bath ?

Did you wipe the area with something like white spirit before applying? This removes any traces of grease that might stop the silicone adhering properly. Make sure the spirit is completely dry before applying.

A plastic bath with flex more than a metal one, so its worth ensuring the bath is filled so it is in the lowest position before applying silicone and then leave filled until the silicone has set.

yes all cleaned off and dry

wiped with alcohol

bath filled overnight

as far as i can see it was done 100% right but its not lasting like it should

Might be the silicon, some of the cheap stuff for around £2 isn't that good. Are you sure its silicon and not just bath sealant. Silicon should last at least 8 years unless there is some other problem

its silicone and the tube states its for bathrooms , baths etc

tbh its no better than the cheapie stuff...maybe i need another brand

Filling the bath will cause it to flex to a lower position, but don't forget that when you bath it will flex slightly more as it has the added body weight as well as the water. I have in the past had to resort to "chocking up" under the bath to restrict any further movement. A bit of a harsh step to take but on that occasion it certainly did the job.

Some of these silicone sealants are mould resistant, others are not. Also, you really need to wipe it down when you've had a bath because leaving the area wet will allow spores to develop into black mould.

thanks for the replys so far

yeah we do wipe it over now..hence the edges lifting

it is a fairly large gap , would i be best run one bead to fill the actual gap , then a week later run another one to tidy it ...or just one fat bead?

i'll try that screwfix stuff next time
