I have a 40000 gallon pool and its free form so I don't know the square footage, but approximately how many tubes of sealant are needed to replace the mortar between the flagstone and pool? like Vulkem45 SSL? or something similar. thank you!
No one can you how much sealant you will use - since no one can see how many feet your trying to work with.
Go to the product's manufacturer website and use their calculator to get any idea of how many tubes you'll need Technical Resources: Sealant Calculator
