Faber DPS — Deep-Penetrating Solvent-Based Water-Repellent Treatment for Natural Stone | Works on Humidity-Damaged Surfaces

Description

Faber DPS — Deep-Penetrating Water-Repellent Treatment for Natural Stone & Agglomerates

Standard water-repellent sealers work well on clean, dry, unaffected stone. They penetrate into the surface micropores and deposit their water-repellent chemistry within the material. But on stone that already has salt efflorescence in its pores, rust staining from moisture contact, or persistent damp damage — standard treatments cannot penetrate effectively. The existing contamination blocks the pathways the sealer needs to reach.

DPS is engineered specifically to overcome this. Its unique solvent-based formulation achieves high penetration even through existing salt deposits and efflorescence — reaching deep into the material structure where the protection is needed most. For stone restoration professionals dealing with humidity-damaged installations, DPS is the treatment that works when others won’t.

The Key Differentiator — Works on Already-Damaged Surfaces

This is what sets DPS apart from every other product in the Faber sealer range:

Situation	Standard Sealer	Faber DPS
Clean, dry new installation	Penetrates effectively	Penetrates effectively
Surface with existing efflorescence	Blocked — cannot penetrate through salt deposits	Penetrates through existing salt/efflorescence
Surface with rust or oxidation damage	Limited penetration near affected areas	Reaches through rust-contaminated zones
Stone with persistent rising damp history	Surface-level protection only	Several millimetres depth — full structural penetration
Surface to be ground/polished after sealing	Protection removed by mechanical process	Depth means protection survives grinding

LEED BD+C V4 Mapped Equivalent Position

DPS is the solvent-based counterpart to the water-based rising damp sealers in the range. For comparison:

	DPS	Hidro Protector MM	Hidro SST
Formula	Solvent-based	Water-based	Water-based
Penetration	Several mm — exceptional	Deep	Deep
Works on pre-affected surfaces	Yes	Limited	Limited
VOC content	High	<0.05%	<0.05%
LEED mapped	No	Yes	Yes
Food contact	Not stated	Yes	Yes
Shelf life	12 months	36 months	36 months

Choose DPS for restoration of humidity-damaged stone where maximum penetration is required and solvent-based chemistry is acceptable. Choose the water-based range for LEED-specified projects, food contact surfaces, and new installations.

Penetration Depth — Survives Grinding and Polishing

DPS penetrates the material for several millimetres — significantly deeper than surface-applied sealers. This depth has a practical professional implication: if the treated stone needs to be mechanically polished or lightly ground after treatment, the water-repellent protection survives the process. The protection is in the stone, not on it.

This makes DPS particularly useful for restoration work where polishing follows treatment, or where a surface showing efflorescence needs to be cleaned and then protected through the same treatment in a single operation.

Key Features

• Works on humidity-damaged surfaces — penetrates through existing salt efflorescence, rust, and oxidation where standard sealers cannot
• Several millimetres penetration depth — protection survives subsequent grinding and polishing operations
• Excellent anti-rising properties — blocks continued moisture migration through the stone body
• Invisible finish — no film, no colour change, natural appearance maintained
• Breathable — moisture vapour passes through the treated surface
• UV resistant and non-yellowing — suitable for exterior applications
• Wet-on-wet second coat — second coat applied immediately crossing the first for maximum penetration
• Indoor and outdoor use
• Shelf life: 12 months — shorter than other products in the range; check date before ordering in bulk

Before use:

• Keep away from all heat sources, sparks, naked flames, and heated surfaces. No smoking.
• Keep container tightly closed. Store in a well-ventilated, cool, locked location.
• Ensure thorough ventilation — dangerous vapours accumulate rapidly in enclosed spaces
• Do not apply in presence of rain, frost, mist, fog, or high humidity

If swallowed: immediately call a Poison Centre or doctor. Do NOT induce vomiting.

PPE required: Protective gloves, protective clothing, eye protection, face protection.

Equipment cleaning: Clean all tools immediately with white spirit.

Suitable Surfaces

Natural stones, marble, limestone, travertine, granite, agglomerates. Indoor and outdoor.

How to Apply

Surface Preparation

• Clean thoroughly, removing all dust and loose debris.
• Never apply to wet or damp surfaces. Apply at surface temperatures between +5°C and +35°C.
• Do not apply in rain risk, frost, mist, or high humidity conditions.
• Protect adjacent surfaces not being treated.

Application

Always test on a small, unexposed area before treating the full surface.

1. Apply an even, generous coat to the clean dry surface using a brush, roller, lambswool applicator, or cloth. Ensure full, even coverage.
2. On highly absorbent materials, apply a second coat immediately (wet on wet), crossing the direction of the first coat for maximum penetration.
3. Wait 10–15 minutes after the last coat for product penetration.
4. Remove any residue with a clean dry cloth. On compact surfaces, a single-disc machine with a soft white pad can assist residue removal.
5. The product is fast drying — within 1 hour of application.
6. Open to foot traffic after 4 hours.
