The Everbuild Everflex 115 General Purpose Building Mastic in White is designed for builders and DIY enthusiasts needing a reliable solution for general pointing and sealing in traditional construction. Its key benefit is excellent adhesion to various surfaces without primer, offering a permanently plastic finish ideal for gap-filling. A potential caveat is its semi-drying nature, which requires an overpaintable layer for a fully finished look and optimal weather resistance.

Yes, it has good external weathering properties and is suitable for perimeter pointing around external doors and windows, especially when painted over for enhanced protection.
No, this product is designed to adhere well to most common clean, dry surfaces like concrete, brick, wood, metals, and glass without the need for a primer.
The skinning time varies depending on temperature and humidity, but a skin typically forms within a few hours. It remains permanently plastic underneath.
Yes, the product is overpaintable once a surface skin has formed, allowing for a seamless finish.
This product comes in a C3 cartridge size, which is a standard size for mastic guns.
Tools and excess uncured mastic should be cleaned immediately after use with white spirit.
'Permanently plastic' means the mastic remains flexible and does not harden completely, allowing it to accommodate minor movement in building joints without cracking.
Ensure the cartridge is properly loaded into the gun and the release trigger is engaged. Check that the nozzle has been cut appropriately.
Verify that the surface is clean, dry, and free from dust, grease, or flaking paint. Reapply mastic to a prepared surface.
This is normal as the product is designed to be permanently plastic. If a harder finish is required, ensure it is painted over once a skin has formed.
Ensure the product is applied in a single, continuous bead. Significant shrinkage may indicate the gap is larger than the product is designed for without multiple applications or a backing material.
Setup: Insert the C3 cartridge into a standard mastic gun. Cut the nozzle to the desired bead size. Apply evenly to clean, dry surfaces, ensuring good contact.
Compatibility: Adheres well to concrete, brick, wood, metals, and glass. A primer is generally not required for these substrates. Ensure surfaces are free from dust, grease, and loose material.
Care: Once applied, a skin will form. This mastic remains permanently plastic underneath. For best results and weather resistance, it is recommended to paint over the mastic once a skin has formed. Clean tools and excess material immediately after use with white spirit.
