Siramico Coatings Liquid Rubber Roof Coating - 5 Litres - Black

No, a primer is not required. The product is designed for one-coat application directly onto the prepared surface.

It adheres to a wide variety of surfaces including asphalt, brick, concrete, GRP, metal, felt, and OSB.

The coverage rate is 1 square meter per litre, so 5 litres will cover approximately 5 square meters.

The coating is designed to provide durable waterproofing protection for up to 10 years.

It is best applied in moderate temperatures (above 10°C). Very cold temperatures can affect application and curing times. Check the product packaging for specific temperature guidelines.

While it forms a durable membrane, it is not intended as a heavy-traffic surface coating. It is suitable for light foot traffic once fully cured.

Tools should be cleaned immediately after use with water before the product dries.

Ensure the product is at room temperature. Stir vigorously. If still too thick, a very small amount of water (no more than 5%) can be added and mixed thoroughly, but this may affect drying time.

Apply in thin, even coats. Ensure consistent pressure with the brush or roller. Work in one direction for a uniform appearance.

The surface may not have been adequately cleaned or prepared. Ensure the substrate is free from dust, oil, or loose particles. Reapply to affected areas after cleaning.

Ensure the correct coverage rate of 1 sqm per litre is being followed. Apply a second coat only if absolutely necessary, ensuring the first coat is dry to the touch. For most applications, one coat is sufficient.
