Do I Need a Paint Primer?

Certain paint colors, especially bright yellows, greens, reds, and oranges, as well as some darker accent colors, are considered "poor hiding” colors. That means, these colors are not good at hiding the color they cover, so they need a colored primer to be applied first.

Using a gray primer (under dark colors) or a tinted primer (under light "poor hiding" colors) can help avoid the need for multiple coats of paint. ECOS colors that benefit from a colored primer are indicated in our color library (Fan Deck View) with a roller icon to help you determine if you need a primer.

Still not sure if you need a paint primer for your next project? Print a zig-zag patterned card that you can use to test your paint sample.

PLEASE NOTE: this guidance relates only to the use of primers with specific colors. Primers are also required when painting repaired, uneven surfaces, or bare substrates that have not previously been coated.

Painting Tips to Improve Color Hide

Besides using a primer, here are some other tips for improving color hide when you're repainting a space:

  • Choose a high-quality paint like ECOS
  • Stir paint thoroughly before painting
  • Don't thin or dilute the paint with water
  • Combine multiple cans of the same color before painting
  • Spread the paint evenly and smoothly
  • Allow the full drying time between coats
  • Use high-quality brushes, rollers, and tools
  • Use the correct primer especially when painting porous surfaces

When To Use Paint Primer

Besides using a primer, here are some other tips for improving color hide when you're repainting a space:

  1. New Drywall - Primer is an absolute must on new drywall (sheetrock and plasterboard) and mudded (joint compounded) surfaces. The new drywall and sanded mud will soak up a lot of paint at first, so the primer works to seal the drywall and create a uniform surface on which to apply the paint. One coat of ECOS Drywall Primer or Air Purifying Drywall Primer will be sufficient
  2. Bare Wood - Some varieties of bare wood soak up even more paint than drywall does, so you definitely need to prime it. ECOS Wood Primer is perfect for many types of wood including plywood and fiberboard.
  3. Stained Surfaces - ECOS Stain Blocking Primer is highly effective at concealing and blocking out difficult stains. If you try to paint over these stains without using a special primer, the stains will bleed through the paint even after multiple coats.
  4. Seal in VOCs - ECOS Air Purifying Primer is a unique primer that can be used on new particleboard, plywood, and other manufactured wood products. If you're chemically sensitive, this primer is designed to absorb formaldehyde and other VOCs, helping to trap them before being released into the air.
  5. Painting Over Dark Colors - As with stains, dark colors can show through lighter ones, so using a wall primer will create the best base coat for your new paint color.

What our customers are saying...

"Genuinely the best paint primer I've worked with! It went on well, had excellent coverage, and I love that it was pet safe. A little went a long way, and it was very easy to work with. Fantastic stuff and better than the expensive "regular" primer at my local paint store."

FAQs About ECOS Paints

  • We typically recommend waiting at least 24 hours before sanding or painting. For best results, please follow the application instructions located on each product page of our website.

  • Primer seals the surface and helps create a bonding layer so the paint adheres better. This creates a more uniform, professional-looking finish and also makes it last longer. Primer also assists with significant color transitions – a must if you're painting a light color over a dark one.

  • Our water-based, eco-friendly primers feature a unique formula created without the harsh chemicals found in conventional primers that often cause headaches, nausea, and worse. Using eco-friendly, sustainable ingredients and a proprietary mixing process, our primers are applied just like any conventional primer, using a brush, roller, or sprayer. Plus, they have better coverage than conventional products, saving you time and money.
