Did you see the small guest bedroom makeover that we did for my son? The bedroom room originally had dark blue walls. The goal of the bedroom makeover was to brighten up the room with a lighter paint color. I decided to use a white paint color by Sherwin Williams Westhighland White and wow, it’s gorgeous!

How many coats of white paint to cover dark walls

Painting over dark walls whether the wall color is blue, black or red is tricky and time consuming especially if you do not prep your wall first with a primer. Especially if you are painting over dark walls with a white paint color. Like I said earlier, the biggest painting tip I can offer is to always use a high quality primer and paint color

As many of you know, we have partnered with Sherwin-Williams for years and I absolutely love their paint.

Steps to Painting Over Blue Walls

  • We applied 1.5  gallons of Sherwin Williams Multi-Purpose Latex Primer over the blue walls. 
  • Once the primer was dry, we applied 2 gallons of Sherwin Williams Emerald Interior Satin Finish Westhighland White Paint color to walls.

A fresh coat of Extra White Semi Gloss trim paint by Sherwin Williams also helped brighten up the baseboard, crown molding, window trim and doors.

This room is fairly small and it only took a day or so to complete the painting project. It’s much more fun to paint with someone vs solo painting. One person rolling the walls and one person cutting in the trim makes for speedy completion!

SW Westhighland White paint color is my go-to white paint color for any wall or space. It looks more yellow on the color swatch than in real life. I highly recommend you always purchase a sample swatch and apply it to the wall you want to paint. Keep it on the wall for a couple days and see if you like the color during the day and evening.

In fact, our entire house is painted Westhighland White. It’s a neutral white that coordinates with warm or cool tones and will absolutely brighten up any space.

  1. Looks Great ! Wondering What’s floor stain color did you used? It looks really nice. Thank you!

  2. I’m in the middle of painting a room that was a dark kind of ecru. The end goal is similar to your Costal Blue.

    Totally agree about using high quality primer. I used Behr.

    Ceiling rolled with a coarse spongy roll. Was not looking for even finish but rather spotty. I’m gonna go over it again the same color, this time by hand with a real sponge.

    Walls still in primer except one that I rolled. I decided that the patter that developed. as I moved along was a Feature, not a Bug.

    Trim pure white high gloss and two interior doors in pure black high gloss.

    Exit door with the same Black and White. Entry door Perfect Purple.

    So much fun!

    I couldn’t help but comment when I saw the banjo. My 27 year old son plays. He got a degree in banjo from ETSU. You just don’t see a banjo picker everyday! The room is beautiful. Stay well. I enjoy your blog! Gina from NC
