How much does a mason cost?
if you do have torch on and its the impressively early stuff you mite be OK ..but the subsequent stuff is absolute hell to remove ..its resembling chewing gum ..if you are lucky enough to remove it afterwards the polyester reinforced stuff is the best on market ...to apply you will want a torch on gun and a good size gas cylinder
