MAINTENANCE OF ACRYLIC STUCCO FINISHES
Lemon Grove Stucco’s Acrylic finishes are Provided by LaHabra Products. We chose La Habra’s product line over other brands because of their local manufacturing plant in San Diego Ca. LaHabra’s durable, strong materials are manufactured to give attractive appearance and longevity. The desired color of the finish is manufactured into the product and does not require painting for many years. The following procedures are suggested to treat acrylic finishes in case of accidental or environmental soiling or minor damage.
General Cleaning information
Lemon Grove Stucco inc./ LaHabra Acrylic Finish can be cleaned using the same cleaning agents that are used to clean acrylic latex paints. Any necessary surface scrubbing should only be done with a soft nylon bristle brush. Always test clean a small inconspicuous area of the finish to ensure no detrimental color or texture change will occur.
Mild Cleaning. Gently scrub the affected area with a solution of dish soap and water. Rinse thoroughly.
Heavy Duty Cleaning. Pressure wash at a maximum pressure setting of 1000 psi. Water up to 100°F may be used. The nozzle of the pressure washer wand should be no closer than one (1) foot from the stucco surface. Do not concentrate the nozzle in one area as this may result in damage.
Cleaning Oily Residue. Mix a 1/4 cup of Trisodium Phosphate (TSP) to one (1) gallon of warm water. Gently scrub the affected area. Rinse thoroughly with water. Caution: Trisodium Phosphate can become a nutrient source for algae growth.
Stains from Wood. Stains from redwood, cedar or treated lumber can be very difficult to remove once they have set on the acrylic finish. If possible, these stains should be removed immediately by one of the cleaning methods listed in the Environmental Soiling section. If the stain does not respond to cleaning, the affected area may have to be sealed and recoated. Please contact Lemon Grove Stucco Inc./ LaHabra Technical Services for options.
Tar and Asphalt Materials. Like stains from woods, tar-like materials can be very difficult to remove. If the Lemon Grove Stucco / LaHabra finish is fully dry and the affected area is small, quick action must be taken. Remove any excess residue taking care not to enlarge the stain. Cold water and/or ice may be helpful in containing the affected area.
Commercial cleansers. Are available that may be effective in removing the stain. Please contact Lemon Grove Stucco / LaHabra Technical Services for more information. In the event that the stain cannot be removed, it may be necessary to seal and recoat the surface with a LaHabra Acrylic coating. Be sure your Acrylic Finish color number is documented.
Rust Stains. Rust stains on acrylic finishes can come from iron or steel construction components adjacent to the installation. To effectively remove the staining, its source should be removed or treated to prevent reoccurrence. To clean the acrylic finish affected by rust stains, use a commercially available Metal Oxide Remover.
Mildew, Fungus and Algae. For installations of LaHabra Acrylic stucco in geographical areas prone to fungus and algae growth, a regular schedule of cleaning is advisable. At the first signs of organic growth the affected area should be cleaned. There are several Mold and Mildew cleaners available for household use.
PATCHING AND REPAIRING
Any occurrence of damage such as.
Dents, punctures, holes, etc. are best repaired by an applicator with experience in the use of LaHabra materials. In some cases, the finish, base-coat and lathing may have to be removed and replaced. Given these circumstances and the variety of damage that can be encountered, the best option is to contact the Lemon Grove Stucco / LaHabra Technical Services Department for specific information on repairs of this nature.
If the finish material must be closely color matched to the existing work.
it is recommended that a physical sample be provided to the Lemon Grove Stucco / LaHabra 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. As per Patching and Repairing, refinishing should be left to an applicator with prior experience in the use of LaHabra materials. 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 LaHabra base-coat should be troweled onto the surface to completely fill the voids created by the original texture. If primer was used in the initial work, apply LaHabra Primer to improve the color consistency and trowel-ability of the new finish. In applying the new finish, follow the instructions given in the LaHabra Product Data Sheet for specific finish and texture desired. Lemon Grove Stucco can apply Acrylic stucco over our sand blasted surfaces.
