Can You Put Siding Over Stucco

February 24, 2021

What to consider when working with stucco

The Ancient Greeks and Romans conceived and used stucco as a malleable yet durable architectural resource. Stucco continues to be used on home exteriors today. When wet, pigments may be added to the architectural material to offer a wide variety of colors.

Though its appearance is unique and its performance is sturdy, stucco is not the most reliable option for home siding today. Many homeowners with this siding find themselves looking for ways to mend faulty cracks once their home settles.

The downsides of stucco may leave homeowners asking, “Can you put siding over stucco without removing the stucco?” Keystone Siding and Windows reviews how to properly install siding over stucco for a new look and structural integrity.

Prep the Wall

The simple answer to whether you can put siding over stucco is yes, with the proper steps. Without adequate preparation, old stucco is likely to crumble under new siding. To avoid compromising the value of new home exterior materials, scrape any loose debris out of cracks. Patch exposed stucco cracks with mortar.

Pro Tip: Because siding will eventually cover these unsightly areas, prioritize the quality of the patch job rather than the appearance.

Install Furring Strips

To provide proper distance between vinyl panels, set vertical furring strips 16 inches apart. You should use two-inch by four-inch strips made from treated wood. This material will prevent stucco from transferring moisture.

In eight-inch increments, pre-drill holes in the furring strips. Using a hammer drill, insert concrete screws the holes while holding the strip in place on the wall. Your strips will then be secured to the exterior.


Insulation is beneficial for home energy efficacy. If you wish to take advantage of insulation’s perks, you will add a layer between the strip and siding installation. Cut foam insulation boards to squeeze between furring strips, utilizing recommended adhesive to ensure a proper hold to the stucco.

Pro Tip: The foam insulation should not be any thicker than the installed furring strips. Using too thick of an insulation layer can result in an uneven siding application.

Hang the Siding

Once you install corner, window, and door trim, you’re ready to hang your siding. Start installing at the bottom of the exterior, keeping the panel flush with the bottom of the still plate.

Each successive siding piece should be installed above the previous one. After each row of siding is installed, check that it’s level before continuing to ensure a professional appearance.
