Application instructions

All substrates should be clean and free from dust, oil, grease or any other contamination which could affect the bond of the sealant.

It is advised to clean non-absorbent surfaces with a solvent followed by a wiping it with clean cloth. Absorbent substrates should be cleaned using clean water.

Joint Backing

Where applicable, appropriate joint filler e.g. closed cell polyethylene foam, should be used to provide the correct joint depth.

Application

Flexseal Bitum is supplied in cartridges and can be applied into the joint using a skeleton gun.

Cut off the cartridge top and the nozzle to the required size then attach the nozzle to the cartridge. Extrude the sealant firmly against the joint surfaces to insure complete contact. Tool the sealant into the joint within 10 minutes of the application, to compact and achieve a good surface finish.

Masking tape can be used on the sides of the joint to maintain the sides clean and uniform. Remove the masking tape directly after tooling the sealant.

Cleaning

Uncured sealant can be removed using DCP Solvent. Cured sealant should be removed mechanically.
