How to Paint Exterior Stucco in Boca Raton, FL

How to Paint Exterior Stucco in Boca Raton, FL

Stucco consists of both powdered limestone or cement, mixed with sand and water until it reaches a mortar-like consistency. It is applied by hand over metal wire or lath, and the stucco then cures to a hard masonry surface, which can last for decades on a home’s exterior. Home owners can update old stucco siding with the application of exterior paint. Stucco holds paint very well, and as long as the stucco is in good condition, prepping for paint is minimal and involves caulking cracks and cleaning the old stucco.  Let’s take a closer look at the steps involved:

Prepare your Stucco for Paint:

First, be sure to remove dust and dirt from the surface of the stucco. This requires only a thorough brushing of the stucco with the bristles of a broom. If the stucco has a deep texture, you might have to use a power washer to get the dirt out of the deepest crevices.

Look for small hairline cracks in the stucco with caulking to ensure water can’t enter later cause damage to your new paint job. For larger cracks, use a putty knife to remove loose debris first and then fill the cracks with a dry stucco repair product.  This is all part of the prep process and this step should not be skipped.  Remember to wait 7-10 days for the moisture to leave the new stucco before painting your house in or around Boca Raton, FL

Paint The Stucco:

Apply one coat of exterior masonry primer to the stucco. Start by brushing the primer around the edges first and then roll on the primer with a thick-nap roller on the wall.

We suggest covering the entire stucco surface with one coat of primer. If the old stucco is a dark color or stained, use a stain-blocking primer to keep the stains from bleeding through. Let the roller do the work, don’t push the roller against the wall or you could end up with roller streaks.  Slow and steady is the best approaching when painting exteriors.

Primer dries extremely fast.  Let the primer dry for the time suggested time before painting.

With your brush, apply a light coat of exterior masonry paint around the doors and windows with a paintbrush.

Roll the rest of the stucco with a large-nap roller, using the roller grid and the 5-gallon bucket to hold the paint for best results.

While the first coat of paint dries, add one or more additional coats, using the same rolling method. Remember that two or more light coats are better than one heavy coat of paint.

Now remove the painters tape around the doors and windows. Hold a straightedge along the edge of the tape and score the edge of the tape lightly with a sharp utility knife. You can then pull the painter’s tape off easier this way.

Tricks of the trade:

If a thick nap roller does not reach the deepest parts of stucco, then the only option is to spray paint the stucco. After proper prep: patching cracks, tape off doors & windows, using plastic to completely cover the doors and windows. Drape nearby structures, such as fences and sheds, before spraying.

For spraying paint, a commercial spray works better than an inexpensive paint sprayer from the hardware store. Sometimes it’s best to just hire a professional instead of purchasing expensive equipment.  Or you can renting one.  This is often less expensive than purchasing a cheaper sprayer, and it’s a better long term investment.
