## Description

Bostik All Purpose Silicon Seal 280ml, White

Review: Bad Batch or Old? - Seem a bit 'stiff' but got half way through the tube with my weaklings grip strength before it seized up. Took off the nozzle and sure enough a big gob of solidified sealant was blocking it. Removed that and got one more squeeze before same happened again. Pocked around with a screwdriver and could feel that most of the rest was solid. Batch number was a bit worn - if the last four digits are the year of manufacture than there's the problem right there! Might be coincidence? Saving grace is that desertcart refunded without needing a return.
Review: Thats it's not solid held back the job. - silicone had gone off solid in tube

### ⭐⭐⭐⭐⭐ Not enough details given.
*by S***N on 4 April 2025*

Having not used it before when I read about it although it didn't say anything about this I only found out from a friend after buying it That I also needed a sealant glue gun to use it, so it didn't really give enough details first.
