MAPEI silicone on worktops

[kilty55]

has anyone come across this before?

i siliconed a splashback today,used a profiler all loked great but after 15 minutes the siliocne started developing bubbles all along it

this happened once before when i siliconed onto a wooden varnished kitchen top this time it was a laminated top

is mapeis silicone not meant to be used in this instance,the fact i t has happened twice suggests something is wrong

Re: MAPEI siicone on worktops

I know someone who had the same problem, did it go wrinkly ? It was out of date.

 

[kilty55]

yes went wrinkly.ahhhhhhhhhhh wheres the date stamp sir?

 

[Scott]

Round the bottom edge of the tube i think

 

[kilty55]

urgh,not chuffed


thanks for the answers guys

 

[Gazzer]

Also it could be caused if the tube has been very cold i believe ...like in the van over night. I think it says somewhere " protect from frost"

 

[kilty55]

i bought them 3 days ago special oreder as it was an odd colour,and left them in customers house so unless its been damaged by frost in the shops delivery van or maybe was out of date i didnt check the date to be honest but i will

 

[Scott]

If its an odd one then sounds like it could be old stock. I also read somehting about a primer prior to using the stuff too? Anyone ever primed anything before siliconing?

 

[kilty55]

just curious as i mostly use mapei silicone tile to tile on bathrooms etc and use all diff colours including ones that arent held stock no issues

only twice i have used on worktops colours and mostly just white tbh which is another brand and both times its gone bubbly,ill look into this as im gonna have to re silicone this job

 

[Gazzer]

If it was an unusual colour then maybe they have had it a while !

I usually carry a dozen or more tubes in my van at a time, never thought of checking dates.
No probs with it mind you yet.

Had this problem with another brand a few years ago, just thought it was the brand so never touched it again, never thoiught about date/frost

Have had this problem with Mapei in the past, and always check date. I think they only have a shelf life of a year, and I send it back if it's less than 6 month till expire date, so they know not to send me it. My Mapie supplier has threatened to stop stocking it as they throw so much of it away, due to the shelf life.

Also, from this time of year, through till spring, I don't leave any consumables in the van. I remove all silicone, addy, grout and primer to protect against frost. As it's cost me a fortune over the years.
