Hi, i need to do epoxy in my garage floor and i realised that there are gap between skirting board and floor which needs to be filled first as i will have to clean garage with water and acid few times.
i got the selleys no more gap (interior) and a chulking gun from store.
wanted to check if the no more gap ( interior) is will be good for this work or should i get a water proof sealant or any other product.
I am not intending to clean garage with a water spray frequently in future ( just few times before epoxy).
