Watco Polyaspartic Primer
Litres required: 0.00L

- Structural strength solutions
Watco Polyaspartic Primer seals porous concrete before a compatible Watco polyaspartic floor coating. By reducing the suction of bare concrete and sand and cement screeds, it helps the finish remain at the surface rather than being drawn unevenly into the floor.
Its clear, two part formulation is suitable for indoor and outdoor coating projects and can be applied at temperatures down to -10°C when the substrate and conditions meet the specification. It can also help when overcoating suitably prepared, firmly bonded existing paint. Use it as part of a specified polyaspartic system, including compatible Watco Cold Set, Fastcoat, Food Safe, Protecta-Coat and Safety Coat products.
- Penetrating primer for porous floors before polyaspartic coatings.
- Clear finish for interior and exterior use.
- Low-temperature application capability with temperature-dependent curing.
Surface Preparation
The floor must be clean, sound and dry. Remove grease, dirt, loose material and laitance using a suitable preparation method. If chemical cleaning or etching is used, rinse thoroughly and allow complete drying. Mechanically prepare existing paint and remove poorly bonded areas. New concrete should normally dry for about eight weeks. Below 5°C, avoid wet preparation where the floor cannot be dried fully.
Technical Data

Coverage
Allow approximately 20m² per 2.5L (8m²/L) in one coat. Coverage can reduce below 0°C or on more absorbent substrates. Apply a thin, even film using the specified microfibre roller.
Directions for Use
- Condition the unopened product at 15–25°C for at least eight hours. Stir each component separately.
- Combine the complete contents, mix thoroughly with a wide bladed tool and scrape the base and sides. Do not dilute or mix more than one pack at a time.
- Roll evenly with a microfibre roller, using a brush for edges. Work promptly within the short pot life.
- The current product page gives floor recoating guidance of four hours at 20°C, six hours at 10°C, twelve hours at 0°C and twenty-four hours at -10°C. Check the chosen finish's instructions before overcoating.
Limitations
Do not apply to damp surfaces or when rain is imminent. Low application temperature does not remove the need to mix warm material or keep the floor dry. Most self-levelling compounds need advice before coating. Protect stored material from freezing and read both component safety sheets. Cure and recoating times depend strongly on temperature and conditions.
Product FAQs
Why use a primer beneath a polyaspartic coating?
It reduces suction in porous concrete, helping a compatible polyaspartic topcoat form a more even surface film.
Can I use it below freezing?
Application is specified down to -10°C on a suitable dry substrate. Mix at 10–25°C and condition the material warm beforehand.
How much will it cover?
Approximately 20m² per 2.5L. Cold conditions below 0°C and highly absorbent floors may reduce coverage.
When can I overcoat?
The current product guidance gives four hours at 20°C, six at 10°C, twelve at 0°C and twenty-four at -10°C. Confirm compatibility with the intended finish.
