Primer Sealer

Hydro Primer Sealer

A hydro primer sealer is a water-based (acrylic) primer used to prepare surfaces before painting. It works as both a primer (for adhesion) and a sealer (to block porosity), ensuring a smooth, durable paint finish.

Hydro primer sealer is a modern, water-based base coat that prepares surfaces for painting by sealing pores, improving adhesion, and enhancing finish quality. It is widely used in residential and commercial painting due to its ease of use, low odor, and cost efficiency.

What is Hydro Primer Sealer?

A hydro primer sealer is a low-VOC, water-based coating designed to:

  • Improve paint adhesion
  • Seal porous surfaces (like cement, plaster, wood)
  • Provide a uniform base for topcoat paints
  • Concrete & plaster walls
  • Brickwork & masonry
  • Wood and metal surfaces (depending on type)

Composition (Typical)

Most hydro primer sealers are made of

  • Binder: Acrylic copolymer (water-based resin)
  • Pigments: Lightfast pigments (usually white)
  • Solvent: Water

These materials make it eco-friendly and easy to apply

Key Features

  • Excellent adhesion to different surfaces
  • Seals pores in cement, plaster, and wood
  • Moisture & alkali resistance (important for walls)
  • Low odor & low VOC (safe for indoor use)
  • Breathable coating (allows moisture vapor to escape)
  • Smooth base for final paint finish

Areas of Application

Hydro primer sealer is suitable for:

  • Interior & exterior walls
  • Cement plaster and concrete
  • Brick masonry
  • Wall boards and drywall
  • Wood and some metals (special variants)

Drying Time

  • Touch dry: 30 minutes to 3 hours
  • Recoat time: 2–8 hours (depending on product)
