How to Use

  • Priming

    Priming is not generally required as SabreSeal MS25 has excellent adhesion to most common construction materials.

  • Application

    Apply SabreSeal MS25 out of the cartridge or sausage into the joint, ensure air is not trapped in the joint.


    Tool surface immediately before skinning


    Remove masking tape immediately, before sealant has skinned off.

  • Painting

    SabreSeal MS25 will accept most water-based paints – test for compatibility. For the best paint bond, apply promptly after sealant cure. Moving joints should not normally be painted as the sealant will be more flexible than the paint coating and can cause crazing of the painted joint surface.

  • Cleaning

    Remove excess sealant immediately with Sabre CC Citrus Cleaner. Ensure surface is solvent resistant before cleaning. Cured sealant can only be removed mechanically.



Is SabreSeal MS25 paintable?

SabreSeal MS25 can be painted with most water-based paints. it should be noted that a wide variety of brands and chemical composition of water-based paints systems are available. It is therefore recommended that technical advice be obtained from the paint manufacturer and/or a limited-on site trial be undertaken prior to full application.

Do surfaces need to be primed before applying SabreSeal MS25?

SabreSeal MS25 has excellent primerless adhesion to most common building materials. Critical applications such as multi-story buildings or exposed areas should be primed for optimal adhesion and durability. If you are unsure, conduct prior compatibility tests prior to full application, or contact Sabre technical support department for assistance.
