  1. Surface must be clean, dry and free from oil, grease, release agents, dust and loose material.
  2. Install backing rod to correct depth apply masking tape as required.
  3. Cut the end of the sausage and insert into a Selleys Sausage Gun.
  4. Extrude sealant into the joint such that it is in full contact with the sides of the joint. Avoid overlapping of sealant to eliminate entrapment of air.
  5. Smooth sealant with spatula forcing the sealant into the joint for better contact with the sides.
  6. Painting with water based paints is possible after curing. If solvent-based paints are used, prime first with water-based primer.

Limitations:
  • *Suitable for most water-based paints. For oil-based paints, undercoat with water-based primer. Testing recommended if paint is applied more than 5 days after the sealant application.
  • Not recommended for continuous submersion or below water line use.
  • Do not use for structural or general glazing.
  • May affect drying of alkyd/oil based paints.
  • White sealant may yellow slightly with age and exposure to the sun.
  • Apply between 5°C and 30°C.
  • Good adhesion properties to building materials indicated without priming. Pre-test to ensure adhesion is suitable.
  • Do not apply in the presence of curing silicone sealants as cure may be affected.
  • Avoid contact with alcohol and other solvent cleaners during cure as cure will be affected.
  • Store unopened sausages below 30°C in a cool dry place away from direct sunlight. Unopened sausages can be stored for 12 months from the date of manufacture. Opened sausages may skin and form a lump near the opening. Discard any lumps or skin and remaining product can be used.
  • Uncured material can be cleaned up with mineral turpentine.
  • Cured sealant can be cut with a sharp blade.
