Acid based product that allows to eliminate rusts stains from granite, particularly indicated to neutralise elements that are inherent in the material and that acquire a yellow coloration, impoverishing the quality of the material.
DERUGGY-STOP is an acid based product used to remove rust stains from granite surfaces. It is especially effective to neutralise those elements in the granite that when exposed to atmospheric agents turn yellowish in colour thus impairing the material quality. DERUGGY-STOP is effectively applied on such materials like Solar White, Camelia White, Kashmir, Panna Fragola, Bianco Kristal, Azularan, Rosa Beta and other types of light coloured granites. This product can be used by slab fabricators
HOW TO USE
For slab fabricators:
- Apply on polished slabs.
- Stir well before use.
- Apply DERUGGY-STOP evenly on the slabs (upwards on vertical surfaces), using a sprayer or a brush a plastic sheeting should be placed between the slabs (do not use wood).
- Leave for 1 to 12 hours depending on the intensity and amount of rust stains to remove.
- Rinse with plenty of clean, fresh water with a brush.
If applied undiluted on light coloured granite, DERUGGYSTOP might darken the surface. It is recommended to dilute as follows: 70 of product: 30 of water.
The efficacy of DERUGGY-STOP can be tested before application.
DERUGGY-STOP can be applied on a sample surface stained with rust: allow to absorb for about half an hour then heat the surface with a flame until perfectly dry.
If the stain is removed, DERUGGY-STOP can be effectively used on the material treated. If the stain cannot be removed, contact our technical assistance. After the treatment with DERUGGY-STOP, it is recommended to apply LITHOS or PRIMALAS/92 or IDROSILAN on the surface. These water repellents in fact, create a barrier between the material surface and atmospheric agents adding protection against oxidation.
Do not apply under direct sunlight.
Consumption is variable and depends on the kind of surface. Approx.1 lt for 10 sq.m.
