Evo-Stik Contractors PVA - White - 5kg

The coverage rate is approximately 6-14m² per litre, depending on the application thickness and the absorbency of the substrate.

The product description focuses on interior applications for plaster bonding. It is not explicitly recommended for exterior use without further manufacturer guidance.

The dilution ratio can vary, but a common starting point for priming is 1 part PVA to 4 parts water. Always test on a small area first if unsure.

It is generally suitable for sealing dusty or chalky backgrounds, which can include previously painted surfaces that have been lightly abraded. However, it is not designed to adhere to glossy or intact paint films.

Drying times vary depending on temperature, humidity, and application thickness. Typically, it dries clear within 1-2 hours, but it's best to allow longer before applying plaster, especially in damp conditions.

Diluted (e.g., 1:4) it acts as a primer to regulate porosity and seal surfaces. Neat, it acts as a tack coat, providing a strong adhesive layer for improved bonding, often used before applying plaster or tiles in specific situations.

Yes, once fully dry and clear, you can apply emulsion paints and other decorative finishes over the treated surface.

This may indicate the PVA was not diluted correctly for priming, or the surface was too absorbent. Ensure proper dilution ratios are followed and apply a second coat if necessary. Allow adequate drying time before plastering.

The surface may not have been adequately prepared (e.g., still dusty or greasy) or the PVA was applied too thinly. Ensure the surface is clean and dry, and apply PVA evenly. For very porous surfaces, a second coat might be needed.

This can occur if the PVA was applied excessively thickly or in very humid conditions. Allow more time for drying, ensuring good ventilation. In most cases, it will fully cure over time, but excessive application should be avoided.

This is usually a sign of the product not drying fully, often due to over-application or poor ventilation. Ensure adequate drying time and ventilation. If minor, subsequent paint coats should cover it.
