Product description
Leakproofs by Betterwork specifies and applies Calista Sparkle PU 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 Calista Sparkle PU is used
This product is specified for walls.
- Exposed metal railings and gates
- Exterior timber joinery
- Surfaces needing higher abrasion resistance
- Trim on coastal and high-exposure buildings
Suitable substrates: Metal, Timber.
How it is applied
Applied over the correct primer for the substrate, in the specified coats. The performance gain over alkyd is real but depends entirely on the priming underneath it.
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
- Harder and more weather resistant than alkyd gloss
- Better UV and colour retention
- Suits metal and timber
- Interior and exterior
- Correct primer is essential
