Primax Power Economy Synthetic Undercoat

---

Primax Power Economy Synthetic Undercoat is a quick-drying primer designed to prepare a smooth, strong and adhesive base before applying the final paint finish. It offers excellent filling and adhesion properties, making it a practical choice for painters, contractors and project users who want a cleaner surface before topcoat application.

A good final finish depends heavily on the surface underneath. If the surface is rough, uneven or poorly prepared, the topcoat may not look smooth and may not bond properly. Primax Power Economy Synthetic Undercoat helps improve the surface by filling minor imperfections and supporting better adhesion between the surface and the final coating.

Its formulation allows easy sanding after overnight air drying, helping painters create a smooth and refined base. This undercoat can be over-coated with synthetic enamel, hammer tone, metallic finishes and automotive lacquers, making it useful for different painting and finishing requirements.

Why Use a Synthetic Undercoat?

A synthetic undercoat is used before the topcoat to improve the final appearance, adhesion and durability of the paint system. It helps create a more even surface and supports better coverage from the finishing coat.

On many surfaces, small defects, sanding marks and uneven areas can appear through the topcoat if they are not properly prepared. An undercoat helps reduce these visible imperfections and gives the final paint a better base to sit on.

Primax Power Economy Synthetic Undercoat is especially useful where a smooth, sandable and adhesive base is required before applying enamel, hammer tone, metallic finishes or automotive lacquers.

Surface Preparation

Proper surface preparation is important for achieving a smooth and durable finish. Before applying Primax Power Economy Synthetic Undercoat, make sure the surface is clean, dry and free from dust, grease, oil, rust, loose paint and weak material.

For wooden surfaces, sand properly to remove roughness and create a smooth base. For metal surfaces, remove rust and old flaking paint by sanding, scraping or wire brushing. The surface should be stable and suitable for coating before application.

A well-prepared surface helps the undercoat bond properly and improves the performance of the complete paint system.

Application Guidance

Application

Apply Primax Power Economy Synthetic Undercoat evenly by brush, roller or spray. Avoid applying very thick coats, as this can affect drying, sanding and the final appearance.

Drying

Allow the undercoat to dry properly before sanding or recoating. It becomes touch dry in approximately 1–2 hours and can be recoated in 4–6 hours under normal conditions. For easy sanding, overnight air drying is recommended.

Sanding

After overnight drying, sand the surface smoothly before applying the final coat. Remove all sanding dust before overcoating to avoid roughness or poor adhesion.

Topcoat Application

Once the undercoat is dry, sanded and cleaned, it can be over-coated with synthetic enamel, hammer tone, metallic finishes or automotive lacquers according to the project requirement.

Common Mistakes to Avoid

Applying on a Dusty or Greasy Surface

Dust, grease and oil can reduce adhesion. Always clean the surface properly before applying the undercoat.

Skipping Rust Removal on Metal

Rust and loose paint should be removed before application. Applying undercoat over rust can reduce the durability of the paint system.

Applying Thick Coats

Very thick coats may dry slowly and become difficult to sand. Apply an even coat according to the surface requirement.

Sanding Too Early

For best sanding results, allow overnight air drying. Sanding too early can damage the coating or create an uneven surface.

Using the Wrong Thinner

Use Mineral Turpentine or Primax Mixing Oil as recommended. Using the wrong thinner can affect application, drying and finish quality.

Applying Topcoat Before Proper Drying

Allow the undercoat to dry properly before applying the final coat. Early overcoating may affect adhesion, sanding and finish quality.
