Alldry Wall Fix 4
Crack-proof waterproofing primer
Alldry Wall Fix 4 is a waterproofing primer with crack-bridging behaviour — the base layer of the Alldry wall system, dealing with fine cracking before the topcoat goes on rather than leaving the finish to span it.

Product description
Leakproofs by Betterwork specifies and applies Alldry Wall Fix 4 as part of a complete waterproofing system. A material on its own does not stop a leak — what stops it is the right material chosen for the right defect, on a surface that has been properly prepared. That is why we deep-scan before we specify.
Where Alldry Wall Fix 4 is used
This product is specified for walls.
- Priming exterior walls before an Alldry topcoat
- Elevations with fine hairline cracking
- Preparation ahead of a combined waterproof-and-repaint programme
- Porous plaster needing sealing before finishing
Suitable substrates: Plaster, Masonry, Concrete.
How it is applied
Applied by brush or roller over cleaned, crack-treated plaster and allowed to develop before the topcoat. Wider cracks are still cut and filled first — a primer bridges hairlines, not open gaps.
Preparation is the part that decides whether the system lasts. Loose material and failed old coatings are removed, cracks are cut and filled, and the surface is cleaned and brought to the moisture condition the product requires before anything is applied. Skipping that stage is the single most common reason waterproofing fails in its first season, whichever brand is on the tin.
