Dr. Fixit Pidiproof LW+
Integral waterproofing compound
Dr. Fixit Pidiproof LW+ is an integral waterproofing compound for masonry, plaster and mortar work. It is the compound most often specified where the water problem is in the walls rather than the slab — external plaster, parapets and brickwork mortar.

Product description
Leakproofs by Betterwork specifies and applies Dr. Fixit Pidiproof LW+ 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 Dr. Fixit Pidiproof LW+ is used
This product is specified for walls, concrete.
- External plaster on windward elevations
- Parapet walls and their junctions with the roof slab
- Bedding and pointing mortar in masonry
- Replastering after rising damp treatment
- Plaster on internal faces of external walls showing damp
Suitable substrates: Masonry, Plaster, Mortar.
How it is applied
Added to the gauging water and mixed through before application, at the dosage given in the current data sheet. Because plaster is applied in relatively small batches, dosage discipline matters more here than on a ready-mix pour — one under-dosed batch becomes one damp patch.
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.
Key properties
- Reduces water penetration through plaster and mortar
- Suited to masonry work rather than structural concrete
- Improves cohesion and workability of the mix
- Compatible with salt-resistant renders used in damp treatment
- Works with, not instead of, an external coating
