A quick trick for smooth nail-fills

The most common repair that walls need before repainting is the fixing of small holes made by pictures or shelves. Whether you’re redecorating or staging, there are some easy DIY steps you can take to make sure that your wall looks smooth and gorgeous when you’re done.

To illustrate these steps, I’m using a personal redecorating project I did a few years ago. We had a large picture wall collage (also called a gallery wall) against a vibrant colour, but with the addition of some new furniture and the changing use of the space as a place to put on boots and shoes, we needed to rethink both colour and style.  This looked, at the outset, to be a big project that I was dreading getting started on.  Just looking at all the repairs I needed to make felt exhausting.  However it went much faster then I anticipated and was actually kind of fun once I got started.  Using the following method made the actual filling of the holes less fussy than usual which had the added benefit of improving my mood as well as cutting down on the time it took to sand them all.

The Original Picture Wall:

So, here is a step-by-step guide to help you get the best results:

First, prepare the wall

1. Remove all the pictures, shelves, nails and screws.
2. Wipe down the wall and trim with a dry or damp cloth to remove dust and cobwebs. If your wall is in a kitchen or bathroom, brush your fingers gently along the surface to feel for grease or soap build up (grease looks shiny and soap is slightly sticky). Remove buildup with TSP all purpose cleaner or soapy water and rinse thoroughly.
3. Remove switch plates. This is an opportunity to inspect them and clean or replace them.

Next, repair the holes

You will need: a hammer, trowel, spackle, sand paper, paint brush or roller.

When you remove a nail, a small lip will form in the wall. If you fill it at this point, there will be a bump on the wall.  It will be difficult to smooth the spackle around the hole, and there will be a lot of sanding in your future to make it appear to be smooth.

Instead, Use a hammer, tap the hole to create a small dent or crater. Do not hit hard enough to break the wall. The goal is to create a small indent where there may previously have been a slight protrusion around the hole.

Like this:

Not like this:

Fill the dent with spackle. Once the compound is in the hole, smooth it with the trowel.  This should be quick and easy as you are filling in the dent only.  Try not to spread spackle onto the surrounding area very thickly - some is going to happen, but smooth it as best you can with the trowel while wet. Once the spackle is dry, sand it smooth with the sandpaper (about 150-220 grit) or a fine sanding sponge. It will end up looking like this:

Now you’re ready to prime and paint!  If you skip the priming step the finish of the spackled spots will be a duller sheen from the rest of the wall.  Primer seals the spackle evenly so that the paint is absorbed evenly and maintains the original sheen.  If you do not have access to primer, an extra coat or two of the finish colour will create enough of a even film over the spackle that the sheen will match very well.  The shinier the paint, the more coats you will need to maintain the desired sheen without primer.  If you are using a flat or eggshell paint, usually three coats will be enough.  If the paint is semi gloss or gloss, expect four coats to maintain the same sheen levels.

Another way to ensure a seamless invisible repair is to use the same tool to paint as the original.  That means if the repair is in a place where a roller was used (this is 95% of the time) use a roller to apply the new coats of paint instead of a paint brush.  Paint brushes and rollers make a different physical textures on the wall and this can lead to visible repairs as it effects both the sheen of the paint and how the light bounces off it.

By taking the time to indent and fill the holes, your freshly painted wall will look great!
