Disclaimers
- Do not pick a colour from a screen.
- Treat any existing mould with rialto SX 5911 before painting — Hydrotex resists new mould growth on the paint film, but won’t remedy mould already present underneath.
- Rialto is unable to guarantee results, as it has no control over the conditions under which its products are applied.
