Usage

Used as a seal between construction components of concrete, lightweight concrete, plaster, plasterboard, gypsum fibreboard, wood, metal, glass and painted substrates.
The sealant should be sized so that the sealant’s movement falls below +/- 20%.

Substrate

Must be clean, dry, firm and suitable for surface treatment.

Treatment

Remove loose material and paint by cleaning and sanding.

Use the correct size/amount of joint sealant, joint depth = ½ joint width.
Narrow cracks and joints are best treated as square joints.

Application

Filler gun.
Cut off the tip of the filler gun.
Cut the tip at an angle to adjust to <joint width.
Easily workable, press into place and smooth using a sealer squeegee or joint stick and water before the joint forms a skin.
Choose a tool based on the width of the joint.
Remove excess sealant mechanically.
Apply sealing tape if necessary and remove it immediately after application.
Cold/ heat can affect the viscosity of the material.
Avoid condensation forming.
Temperature and atmospheric humidity affects drying time, full curing and recoat interval.
Always perform a test treatment for a check and acceptance of adhesion and result.

Be Aware

Joints < 6 mm or > 30 mm do not absorb maximum joint movement.
