Matching Drywall Texture After a Repair

By Lemoon's Painting

Most San Diego homes have one of four interior wall finishes: orange peel, knockdown, skip trowel or smooth. A drywall patch blends in only when its texture matches the wall around it in pattern, size and height. That is done by reading the existing texture, testing the mix and spray on scrap board, applying it over a primed patch, and checking it after the first coat of paint.

Drywall is rarely left perfectly flat. Most of the interior walls in San Diego County carry a texture, applied after the board was taped and finished, partly for looks and partly because texture hides small irregularities in the surface. When a section of that wall is patched, the patch is smooth. Unless the texture is rebuilt over it, the repair will show as a flat, slightly shiny window in the middle of the wall the moment the light crosses it.

Rebuilding that texture is what makes the patch disappear, whether the repair was a nail pop, a doorknob hole, a removed fixture or a section of board replaced after a leak.

What are the common drywall textures?

Four finishes cover almost every home here. Orange peel is a fine sprayed spatter with rounded bumps. Knockdown is a heavier spatter flattened with a wide knife before it sets. Skip trowel is compound applied by hand with a curved trowel, leaving irregular flat patches. Smooth has no texture at all and is the most demanding to patch.

Orange peel

The most common wall texture in tract and master-planned housing from the last few decades, including much of Eastlake and Otay Ranch and Santee. It is sprayed on as fine droplets of thinned joint compound and left to dry as they land. Up close it looks like the skin of an orange. The variables are droplet size and density, and both depend on how thick the mix is, the size of the nozzle and the air pressure.

Knockdown

Larger splatters, sprayed on and then flattened with a wide knife as they begin to set. The result is a pattern of smooth, flat-topped islands with low valleys between them. It is popular on ceilings and in living areas. Timing is the hard part: knock it down too early and it smears, too late and it tears.

Skip trowel

Applied entirely by hand. Compound is skimmed across the wall with a curved trowel held at a low angle, so it catches and skips, leaving irregular flat patches. Each installer’s hand is a little different, so matching skip trowel is as much about copying a rhythm as copying a texture. It shows up in homes that wanted a hand-finished, older look.

Smooth

A wall finished flat, with no texture. It is the standard in many older homes and in higher-end renovations, where a fully skimmed surface is called a Level 5 finish. It looks the plainest and is the least forgiving to repair, because there is no texture to hide an edge.

Why textures are hard to match

Three things make a patch stand out even when the texture type is right:

  • Scale. An orange peel with fine droplets next to one with coarser droplets reads as two different walls.
  • Height. Texture that sits higher or lower than the original casts different shadows.
  • Age. A wall painted three or four times over twenty years has had its texture softened. The tops of the bumps are rounded and the low points are partly filled. Fresh texture is crisp by comparison.

The age issue is the one that catches people out. A patch that looks perfect before painting can look too sharp afterwards, because the old wall’s texture is under layers of paint and the new one is not.

How a texture match is done

  1. Finish the patch flat first. The drywall repair is taped, coated and sanded smooth and level with the wall. Texture is not a filler; it goes over a flat surface.
  2. Prime the patch. Bare compound absorbs moisture from the texture mix at a different rate from the painted wall, which changes how the texture dries. A primed patch behaves like the wall around it.
  3. Read the existing texture. Size, density, height and, for knockdown, how flat the tops are. A light held flat against the wall shows it clearly.
  4. Test on scrap. The mix and spray settings are tried on a piece of scrap drywall or cardboard, primed and painted if possible, and adjusted until the test matches.
  5. Apply and feather. Texture is applied over the patch and lightly past its edges, with the density tapered at the border so there is no visible frame around it.
  6. Knock down, if it is knockdown. At the point where the sheen of the wet spatter dulls, the knife is pulled across lightly in the same direction as the original.
  7. Let it dry fully, then prime the new texture.
  8. Paint, and judge the result after the first coat.

Why the sheen of the paint matters

The finish you choose affects how much any repair shows. Flat and matte paints scatter light and are the most forgiving of slight differences in texture. Eggshell and satin, which many homeowners prefer for washability, show a little more. Semi-gloss on a textured wall makes every variation visible. Ebenezer uses Dunn-Edwards and Sherwin-Williams, both of which offer interior lines in the full range of sheens, and he will tell you honestly which one suits the walls you have and the way you use the room.

Painting the wall from corner to corner after a repair matters too. A textured patch with a touch-up of paint on it will often be visible as a different sheen, even when the texture is right.

When the answer is to re-texture the whole wall

Sometimes a patch cannot be blended into its surroundings: the original texture was inconsistent, the wall already has several old patches in different textures, or the repair covers a large part of the wall. In those cases the honest choice is to texture the entire wall, corner to corner, so it reads as one surface. It takes longer, and it is often the only way to get a wall you will not notice.

Older homes add one more caution. The EPA lists textured materials used on ceilings among those that may contain asbestos, so an acoustic or popcorn ceiling in an older house should be tested before it is sanded, scraped or cut. In the older stucco tracts of Chula Vista it is worth asking before any ceiling work begins.

Why this is worth doing right

A wall with an obvious patch is a wall you see every time you walk into the room. A wall with a well-matched patch is just a wall. The difference is in the reading, the testing and the patience between coats, the kind of detail Ebenezer means when he says, “Paint to me is an art.” Ebenezer repairs the drywall, matches the texture and then paints it.

If you have a repair coming, or an old patch that has always bothered you, ask for a free estimate. Ebenezer will look at the texture on your walls in the light the room actually gets and tell you how close the match can be. The stucco, drywall and wood repair page sets out what is included.

Common questions

How can I tell orange peel from knockdown?

Run your hand across the wall. Orange peel is a fine, even, bumpy surface, like the skin of the fruit, with no flat tops. Knockdown has larger splatters that were flattened with a knife while wet, so you feel smooth raised islands with low valleys between them, and you can see the flat tops in side light.

Do spray cans of drywall texture work?

They can work on a patch the size of a nail hole or a switch-plate opening. On anything larger they tend to give an uneven pattern that is hard to blend, because the spatter size changes as the can empties. Larger patches are textured with a hopper gun and compressor and a properly thinned mix.

Why does a texture match look right until the wall is painted?

Older walls carry several coats of paint, which round off the tops of the texture and partly fill the low spots. Fresh texture is sharper. After the first coat the difference shows. A good match is built slightly softer than the original, and judged after primer and paint, not before.

Is a smooth wall harder to patch than a textured one?

Usually, yes. Texture breaks up light and hides small flaws. A smooth wall shows every ridge, edge and dip, especially in a glossier sheen. A smooth patch is feathered very wide, sanded with care, and checked in raking light, and a flat or matte paint hides what remains best.
