If your going to be painting a stucco house, cinder block wall, pardging or a brick surface,

such areas are made of porous materials and require different techniques when painting than a regular wood siding wall.

Below you will find advice, for painting exterior surface’s of your home that are sometimes difficult to coat.

If on the other-hand, your not looking for information on painting a porous surface, then use the home link at the bottom of this page to help you find the painting or decorating advice your looking for.


Whether your painting a stucco house, cinder block, pardging or brick wall, you will need to do the usual masking and covering of surface area's that you don't want to get paint on.

Also, make sure the materials being coated, are dry and completely clean of dirt and debris.

Surface dryness is important, especially if the surface being painted is brand new. Porous surface’s that are new, like cinder block or pardging, can tend to cause paint to peal if they are not left to completely dry before painting.

If you are dealing with a new surface, ask the contractor (or material supplier) who did the work, for information regarding the best time to begin painting.

Before you start painting a stucco house, cinder block wall, pardging or brick surface, fill all holes with an exterior filler and caulk any cracks using a good quality exterior paintable caulking.

If your surface has a number of hair line cracks, you may want to try applying two or more coatings of elastomeric, as opposed to a regular latex paint.

With that said, paint contractors have been known to dampen a porous surface just before coating, so as to make the painting process easier and paint product stretch farther.

I wouldn't advice the average home owner to attempt such a wetting and painting system, unless they have a complete understanding of the process.

Depending on the surface and product used, you may need to apply a primer. Primers specifically designated for the area being coated will work the best.

Be sure to check with your local product or material supplier to see if a primer is needed, when you paint a stucco house, cinder block wall, pardging or brick fence etc.

I would rather use my paint sprayer, when coating a porous surface, than brushing and rolling the surface. If you decide to use a sprayer, you may find that a certain amount of practice is needed with the equipment being used.

Nooks, crannies and an assortment of textured highs and lows will cause you to angle your spray gun in a number of ways. Angling the gun helps to get your project entirely coated with paint.

When one starts twisting and turning a spray gun at different angles, runs and sags are almost inevitable. When runs and sags happen, you may want to immediately back roll using a damp (with paint), roller/cover.

When brushing and rolling porous surfaces use duct tape (to protect areas) prior to cutting in. Bumps and grooves don't brush very well and the tape will help keep somewhat of a strait painted edge.

If you where to paint a stucco house, or cinder block wall without using painters tape the project would take forever and more than likely not look like a professional job.

To coat a porous surface, the paint roller cover needs to be quite nappy (ask your paint dealer regarding thickness). You may also find that a little elbow grease is required, along with some pushing and prodding, otherwise getting into all those cracks and crevices won't be possible.

Nappy roller covers, usually fill up with chunks of the wall your painting, pick out the bigger chunks (with rubber gloved fingers) so that you don’t track up your painted surface.

When painting a stucco house your roller cover tends to get filled with debris, you might want to replace the cover with a new one. Washing in most cases, usually doesn’t get a clogged roller cover very clean.


Regular exterior latex, in a flat finish is normally the recommended coating for painting a stucco house, if the surface being painted has little or no cracks, hardly any bumps and few crevices.

If you do have a crack or two, be sure to caulk them with a paint-able caulking, before you begin your painting project.

Most porous surface’s need to breath, so alkyd or oil based paints are not normally recommended as a preferred coating. With that said, products are always changing, so be sure to follow all the coating instructions and guidelines that are recommended by the manufacture before you paint a stucco house, cinder block wall, pardging or brick surface.

Waterborne is a higher quality latex product and will bridge over and fill cracks better than regular exterior latex, but with higher quality, comes a much higher cost.

When painting a stucco house a product that I would not consider the most effective for covering surface cracks is Stucco Coat.

I have yet to find a stucco coat that works as per the specifications. Stucco coat is a thicker product but doesn’t seem to do any better a job than regular exterior latex, yet it cost more due to it's lower coverage.

I like elastomeric products even though they can tend to be over-priced.

Rolling your siding is fine though sprayed on elastomeric usualy gives a flat uniform finish and will cover most cracks unless they are on the larger side (1/16th to 1/8th of an inch wide or more). A problem you might find, if your thinking of spraying an elastomeric product, is locating a paint sprayer that's big enough to blow the product out of the sprayer.

Some elastomerics have a consistency of sour cream. Another thing to keep in min when painting a stucco house is that elastomeric in most cases will coat a larger area than what is suggested on the label. When buying, elastomeric, purchase just enough for the first coat then go back to the paint store and buy what’s needed for the last.

Your final coat, will usually require one half, to three quarters of what you used to do the first coating.

If you intend on adding color and your not looking to cover imperfections or bridge gaps on a raw un-painted surface, you might want to apply a stain. Exterior stain is cheaper than paint and will in most cases last just as long.

Before applying your stain, be sure to test in an inconspicuous spot. You wouldn't want to start rolling stain onto the pardging for instance and find you don't like the look.
