Watco Masonry Waterproofer
Litres required: 0.00L

- Structural strength solutions
Watco Masonry Waterproofer is a penetrating cream treatment for protecting porous exterior masonry against wind-driven rain. Its silane and siloxane formulation lines the pores of the material to repel water while allowing the wall to breathe.
The white cream makes freshly treated areas easy to see, then penetrates and turns clear so the appearance of brick, stone or concrete is largely retained. It is suited to sound, unpainted masonry above ground level where a clear water-repellent treatment is preferred to a coloured coating. The cream can be applied with a roller, with a brush used around frames, deeper mortar joints and other details.
- Clear-drying, breathable water-repellent treatment.
- For suitable porous brick, stone, concrete and masonry.
- Usually one coat, without a separate primer.
Surface Preparation
The surface must be clean, dry and absorbent enough for the cream to penetrate. Remove growth and loose material by wire brushing and repair cracks or open joints before treatment. Do not use detergents to prepare the wall. Newly pointed areas must be at least seven days old. Larger crevices need a suitable repair rather than relying on the waterproofer to bridge them.
Technical Data
| Pack size | 5L |
|---|---|
| Composition | Single pack, silane siloxane emulsion |
| Finish | White cream that dries clear |
| Intended use | Exterior masonry above ground |
| Minimum application temperature | 10°C |

Coverage
Approximately 25m² per 5L (5m²/L), depending on the porosity and texture of the masonry. One coat is usually sufficient. Measure the area and allow for detailed or highly absorbent surfaces.
Directions for Use
- Check a small inconspicuous area if the final appearance is important.
- Apply evenly by roller, using the temporary white appearance to check coverage.
- Brush into deep mortar beds, joints and areas the roller cannot reach. Treat carefully around window frames.
- Wipe splashes from paintwork or glass within a few minutes. The cream starts turning clear in about an hour; maximum penetration is generally reached after twenty-four to forty-eight hours.
Limitations
Use only on porous, unpainted surfaces. The treatment is intended for above-ground rain protection and will not solve rising damp or hydrostatic pressure below ground. It is not a crack filler: the technical sheet describes lining pores up to 0.3mm wide, with wider gaps needing repair. Drying and penetration depend on weather and substrate absorption. Store away from heat and direct sunlight and follow the safety sheet.
Product FAQs
Will it change the brick colour?
The cream turns clear as it penetrates, helping retain the masonry's appearance. A small trial is sensible where appearance is critical.
Will it stop rising damp in a cellar?
No. It is intended for above-ground masonry protection against rain, not below-ground hydrostatic pressure or rising damp.
Can it be applied over masonry paint?
No. The surface must be unpainted and porous so the waterproofer can penetrate.
How long before the treatment becomes clear?
It starts turning clear in around one hour and generally reaches maximum penetration in twenty-four to forty-eight hours, depending on conditions.
