How to Identify and Match Your Stucco Texture

Most complaints about stucco repair are not about the repair. They are about the fact that you can see where it happened.

That is a texture and colour problem rather than a structural one, and it is worth understanding before anyone quotes you, because it is the part of the job that decides whether you are pleased in a year.

First: identify what you have

Stand about ten feet back, then go right up to the wall. Both distances tell you something.

Lace, or lace and skip. A raised, irregular, mottled pattern with flattened high spots and recessed low areas. Applied by splattering material on and then knocking down the high points with a trowel. Overwhelmingly the most common texture on Southwest tract housing, and the most commonly botched, because the knockdown timing is a feel thing.

Dash, or knockdown dash. Material splattered on and left, or knocked down only slightly, giving a uniform stippled or popcorn-like surface. Coarser than lace and with less flat area.

Sand or float finish. A uniform, grainy, relatively flat surface with no raised pattern, in fine, medium or coarse aggregate. Looks simple and is the least forgiving to patch, because there is no pattern to hide a transition in.

Santa fe. A mostly smooth, hand-troweled surface with subtle undulation and softened edges, often with rounded corners on the building. Common on anything built to a traditional New Mexico look.

Worm, or perlite. Distinctive wandering grooves cut into the surface by aggregate dragged under the trowel. Less common now, very recognisable, and a genuine skill to reproduce.

Smooth troweled. Flat and hard-edged. Shows everything, including the patch.

the Mesilla Valley note. In Las Cruces and through the Mesilla Valley, lace dominates newer tract construction and santa fe and smoother troweled finishes appear on anything built to a traditional look, including a great deal of the older stock in and around Mesilla. Genuine adobe and older hand-applied work is its own category: there is no product that matches it off a shelf, and anyone who says otherwise has not tried.

Second: coloured through, or painted?

Find a chip or a crack and look at the edge.

• Colour goes all the way through the finish coat → integral colour. You are matching a material, and the match has to be mixed.
• Grey or white underneath a thin skin → it is painted. You are matching paint, which is much easier and much cheaper to get right.

If you cannot tell, scratch a hidden corner with a key. This single question changes the whole approach, so it is worth doing before you call anybody.

Why patches show, and what actually fixes it

Texture is hand work. Two competent people produce visibly different lace. The way to get a match is for whoever patches it to look at your wall, mix to the aggregate size on it, and practise the technique on a board before touching the house. Anyone who goes straight to the wall is guessing.

Sun has aged the colour. Fifteen years of ultraviolet on a south elevation moves pigment a long way from where it started. A perfect batch of the original colour will read as newer than the wall. Matching is done against the wall as it exists now, in daylight, not against a record.

Edges telegraph. A patch that stops in the middle of a flat wall leaves a boundary the eye finds, however good the texture is. The fixes are to feather the new texture out over a wider area, or to carry the finish to a natural break, a corner, a control joint, a trim line, the edge of an elevation.

That last one is the difference between a cheap quote and a good result, and it is the thing most worth asking about when you compare bids. A quote that only prices the damaged square footage is pricing a visible patch.

What to ask whoever quotes it

1. Which texture do you think this is? If they cannot name it, they cannot match it.
2. Is the colour integral or painted? They should check rather than assume.
3. Will you sample the texture on a board first?
4. Where will the new finish stop? The answer should be a natural break, or an explanation of how the edge is feathered.
5. Will you match the colour against the wall in daylight?
6. What happens if it does not match? A real answer exists for this.

When a coat beats a patch

Sometimes the honest recommendation is not to patch at all.

If a wall has multiple repairs, significant fading, or a texture that will not take a discreet edge, coating the full elevation with an elastomeric coating or a restucco gives you a uniform surface and removes the matching problem entirely. It costs more than a patch and less than being unhappy with three patches.

When that’s the case, the cheap version only ends up paid for twice. The restucco cost calculator prices the full-elevation route and the repair calculator prices the patch, so you can compare them before anyone visits.

Get it looked at

Photograph the damaged area close up, the same wall from about ten feet back, and a chipped edge if there is one, in daylight. Those three usually let a plasterer name the texture, say whether the colour is integral, and say whether this is a patch or an elevation. We cover Las Cruces, Mesilla, Doña Ana, Anthony, and Hatch, and the full ranges are on the pricing page.
