Acrylic Stucco FAQ

Acrylic Stucco FAQ

 1. Should I expect Acrylic Stucco to crack? When should I be concerned with cracking?

As houses settle over time, certain building products have more or less flexibility.

While the final coat of acrylic stucco is flexible, elastomerics are more flexible. Sometimes, cement substrates can be brittle and will produce cracks that may “telegraph” to the surface. These are normally small hairline cracks that do not affect the performance of your wall. However, if the house begins to develop cracks wider than 1/10 of an inch (the thickness of a nickel) then the stucco cracks will need to be patched. If the wall is significantly shifting, you will need to contact your home builder.

 2. What options do I have for repairing my acrylic stucco finish?

Any occurrence of damage such as dents, punctures, holes, etc. are best repaired by an applicator with experience in the use of Acrylic materials. In some cases, the finish, basecoat and lathing may have to be removed and replaced. If the finish material must be closely color matched to the existing work, it is recommended that a physical sample be provided to Lemon Grove Stucco Color Department for analysis and matching. Even then, the new finish can appear somewhat different than the original finish due to age or a difference in the texturing technique of the applicators. If a wall surface must be refinished, it may be more acceptable to resurface the entire panel or larger area to an existing break or termination, rather than a smaller patch area. The area must first be cleaned by one of the methods listed above. Secondly, on the clean and dry existing finish, a skim coat of basecoat should be troweled onto the surface so as to level it. If primer was used in the initial work, apply Acrylic Primer to improve the color consistency and trowelability of the new finish. In applying the new finish, follow the instructions given in the Product Data Sheet for specific finish and texture desired.

 3. My house has changed color from when it was new: Is this normal?

Most products when left outdoors will change color over time given changes in temperature and exposure to ultra violet (UV). While traditional stucco will darken with age, acrylic stuccos will lighten as composition polymer resins changes with time. This change in color in no way affects the performance of the stucco, but periodic recoating of acrylic stucco will keep your home’s exterior beautiful.

 4. What is the darker, fuzzy growth appearing along the bottoms of the stucco walls near my flowerbeds? What can I do about it?

This sounds like colonies of mildew. These microscopic organisms are part of the natural life cycle of organic matter, including decay and composting of landscaping materials or mulches. Excessive moisture in flowerbeds, shrubs and other organic materials creates ideal growing conditions for these organisms. It can be prevented, or minimized, by eliminating excess moisture:  be sure irrigation systems are not directed against walls and keep plants trimmed back to allow ample light and air circulation. Remove the discolorations by following the directions outlined previously in the stucco maintenance section.

 5. Do acrylic stucco’s stay cleaner than traditional stucco?

Yes they do Lemon Grove Stucco uses  LaHabra’s acrylic stucco that is specially formulated with a Dirt Pick-up Resistant (DPR) technology that forms a hard layer on the surface of the coating reducing the surface tack as the finish cures. The hard surface makes the coating more difficult for dirt to adhere to the face of the finish. The acrylics used maintain their original performance properties such as high adhesion, good water resistance, longevity and excellent resistance to cracking and chalking longer than many other acrylic stuccos.

 6. How can I change the color of my stucco?

Lemon Grove Stucco’s Acrylic finishes generally remain attractive for many years of service. However, should there ever be a need to refresh or change the color of your home, we strongly suggest the use of LaHabra DPR Coating. Caution: Using paint and another acrylic coatings will alter the sheen and texture of the original finish. Before attempting to refresh the acrylic stucco color, be sure to consult your HOA (if applicable ) and/or Lemon Grove Stucco for proper use and procedural guidelines.Acry
