PW 1005_PVA Primer

Ritver PVA Primer is a copolymer-based primer designed to penetrate into bare surfaces like masonry, plaster, brickwork, and other bare constructed structures.
It has excellent adhesion to cementitious surfaces, forming an ideal surface for subsequent coats.

Substrates: Concrete, plaster, masonry, gypsum.
Area of Use: Interiors Use.

A good surface preparation and adhering to the method statement or recommended system procedure of Ritver is strongly recommended for the application of Ritver PVA Primer.

For Plaster, Masonry & Concrete:
Ensure a clean surface by removing all contaminants and loose particles through cleaning and drying.
A laitance-free surface should be achieved by sweep blasting or using a wire brush. Water washing under pressure is also recommended.
Apply Ritver Primer Sealer and allow it to dry as per the data sheet. Apply a second coat if needed for full coverage.

For Old and Painted Surfaces:
Remove all loose material by scraping or using a metal brush.
Apply a coat of Ritver Fungicidal Wash Compound and allow it to dry.
Then apply one or two coats of Ritver PVA Primer.

Adequate ventilation is mandatory as it helps in drying and ensures proper application.
Avoid high humidity conditions (i.e., >95%) when condensation is likely to interfere, and ensure the surface temperature is at least 3°C above the dew point.
Add 5–10% clean (sweet) water for ease of application.

1. Brush: Recommended especially to avoid runs and sags caused by excess material.
2. Roller: Apply an even coat, spreading uniformly and taking care to avoid runs.

Under dry and cool conditions, the product remains stable for up to 12 months in its original sealed container.
