Paint Over Silicone

Uses

Ideal sealant around bricks & concrete, window frames, tiled and wooden fixtures, particularly when the sealant will be painted. Optimum adhesion is achieved on ceramics, glass, most metals, most plastic, rubber, glass and cement.

Product Range

• Size & Pack Type: 380g cartridge
• Color: White

Technical Features

• Good adhesion to most building materials
• Can be used on damp surfaces
• Neutral cure
• Water clean-up while still wet
• Can be painted over with oil & water based paints within 48 hours
• Smooth finish
• Forms a durable seal
• No odour during application
• Remains flexible – will not crack, crumble or dry out once cured
• Weather resistant

Application Tips

• Should not be used in permanently damp locations, or in below ground or in below water line applications
• May be discoloured by contact with alloys containing brass, copper or zinc
• Do not use in freezing or rainy conditions. Protect from rain for at least 1 hour after application. Do not allow unused product to freeze.
• Ability to accept paint is reduced over time
• For a cleaner appearance mask both sides of joint prior to sealing. Remove tape before silicone skins.
• To improve paintability with water based paints, wipe with detergent solution immediately before applying paint
• Avoid smearing on surfaces which are to be painted as this may affect the paintability of these surfaces. Smears dry quicker than thick beads rendering the surface non paintable in less time.

Technical Details and Performance

Indicative information only, not to be used for setting specifications.

Consistency (as applied)

Non-slump, solvent free paste

Curing Mechanism

Very rapidly develops rubber consistency by water evaporation

Curing Rate

2mm depth per day

Skin Forming Time

10-15 minutes (longer in damp or cold conditions)

Elongation

Approx. 800% (ASTM D412). 21 days cure

Service Temperature

-40oC to +93oC

Joint Movement Capability

±25% of original joint width when applied in properly designed joint*

Clean Up

Clean all excess sealant from equipment before it cures with a damp cloth. Once cured, sealant is extremely difficult to remove and must be abraded or trimmed with a knife.

Cured sealant can also be removed with Selleys Silicone Remover

Properly designed joint refers to the accepted concept of correct sealant dimensions, i.e. sealant depth equal to half sealant width and sealant applied over a suitable backing material to which the sealant will not adhere or which does not limit the free movement of the sealant.
