Remember all animals are equal...........But some are more equal than others!
Getting back to the question in hand.
When you say dry do you mean set? Weber will be the fast setter and Parex the slow setter.
Thanks mate, to be honest I used parex yesterday for the first time, I had it sprayed by 9am but it took ages to dry, the lads didnt finish till 630 with clear up ect, i thought it seemed slower but was not sure as it was on top of engineer bricks which have obviously got no suction and I also microgebetis it, plus the sun was on the other side of the house :-(
At least I know what to use in the winter so the next day scrapes are not too hard
