With large projects and the amount of gaps that often require sealing, a 300ml requires a very frequent changeover which can cost time. With the use of an Acoustic and Intumescent it helps with smoke prevention in the case of a fire by expanding with the heat and remains viscous and flexible under the correct temperature range as hardening will cause vibration to transfer in to the adjacent surfaces.

At first you will want to cut the nozzle to a pea size opening  for an approximate 5mm bead application and puncture the tin lid on the inside with a screwdriver or other device long enough, forgetting to do so could cause the adhesive to come from the other end when pressure is applied to the applicator gun.

When dried the sealant will remain a white colour, the sealant can be sanded down and painted over during decoration.
