Primers: What You Need to Know

Primers, also referred to as undercoats or preparatory coatings, are essential for promoting adhesion between surfaces and topcoats, preventing peeling, and improving finish quality. They’re available in a range of bases and formulations to match interior, exterior, and specialty surface requirements.

Base:

  • Acrylic: Water-based primers made with acrylic resins for excellent adhesion and durability. Fast-drying and suitable for drywall, wood, and masonry.
  • Latex: Flexible and easy to clean, latex primers are ideal for residential applications. Low-VOC content makes them environmentally friendly and user-safe.
  • Oil: Known for strong adhesion and superior stain blocking, oil-based primers are best for wood and surfaces with tough stains. Longer drying time is offset by long-term durability.
  • PVA: Polyvinyl acetate primers designed specifically for new drywall. They reduce surface absorption and promote consistent paint application.
  • Shellac: Offers exceptional stain-blocking for water, smoke, and tannin bleed. Suitable for sealing knots and spot-priming problem areas.
  • Water: Eco-friendly water-based primers that clean up easily and dry quickly. Compatible with most topcoats and ideal for indoor use.

Features:

  • Primer: Standard basecoat that enhances paint adhesion and creates a uniform finish. Suitable for most residential and commercial painting projects.
  • Primer & Sealer: Dual-action formula that seals porous surfaces and primes in one step. Reduces the need for multiple coats and improves final paint appearance.
  • Primer & Sealer Spray: Combines sealing and priming capabilities in an easy-to-use spray format. Perfect for touch-ups or hard-to-reach areas.
  • Spray Primer: Delivers smooth, even coverage in aerosol form for small jobs or tight spaces. Great for furniture, décor, or patch repairs.
  • Spray Primer & Sealer: A high-performance aerosol product that seals and primes simultaneously. Designed for convenience without compromising on quality.

Applications:

  • Concrete: Designed for porous surfaces, these primers penetrate and seal concrete to ensure strong paint adhesion and prevent chipping. They provide a smooth base layer ideal for masonry and cementitious substrates.
  • Drywall: Formulated to seal new drywall, these primers prevent blotchiness and enhance topcoat uniformity. They also reduce paint absorption for improved coverage and finish.
  • Interior: Tailored for indoor use, interior primers offer low odor and quick drying properties. Suitable for walls, ceilings, and other common indoor surfaces.
  • Metal: These primers protect against rust and corrosion while offering solid bonding for topcoats. Ideal for galvanized, bare, or previously painted metal surfaces.
  • Multi-purpose: Engineered for versatility, multi-purpose primers can be used across various surfaces including wood, drywall, and masonry. They’re a convenient choice for both repair work and new installations.
  • Rusty Metal: Specially designed for corroded surfaces, these primers neutralize rust and prepare metal for painting. They deliver added protection in high-moisture or industrial settings.
