Hi we're looking for a half hour or one hour (to suit domestic building regulations) intumescent paint to apply to 2 universal beams approx 7m in length, that are to be left exposed internally. Ideally we're looking for a paint on solution with one coat application and choose a ral colour or choose from of colours available rather than just white (ideally an anthracite grey) However if 2 coats are required we can do that also. Could you please advise on product and the amount of paint required along with a price to supply. Many thanks and kind regards. Peter smith
