Sealing a back patio - Bad weather.

[ajw]

hi i have jet washed someones back concrete blockpaving patio and have been waiting nearly a month to attempt to seal it with resiblock superior. its been raining most of the time and because you have to have a minimum of 12 hours without rain its been impossible to do. its very frustrating and i dont think it will be done for ages. what would i do if i had loads of sealing jobs waiting? is there anyway anyone has any tips? can you cover the area with a tarpaulin or something? please help. the joints have to be dry aswell as the face of the blocks so you need a good few days of dry weather. what would happen if it rained after the second coat was applied within an hour or so?/

The only "tip" is to save all your sealing jobs for the summer. Covering the site is all but impossible, especially on larger jobs, and even if you could cover the entire job, you;d be unlikely to exclude damp from penetrating.

Rain can turn the sealant milky. Don't risk it.
