FAQs
 
 
  • The difference in these unique finishes is the gradation of the aggregates to achieve a scope of finishes from course to smooth.
  • A wide variety of custom colors are available in our lab for viewing. Samples of colors are available upon request.
  • Some colors cannot be replicated with cement-based stucco. These are usually very dark or high intensity colors.
  • Precise matching of existing stucco is difficult. Environmental conditions and age will cause variations in the original color. Fog coating may be necessary to blend in new and old color coat
  • Depending on the color, stucco will usually lighten with age. However dirt, soot, and environmental contamination will darken the color coat.
  • A leveling coat of plaster applied to the wall prior to the color coat prevents the grout lines from shadowing through the color coat. It also levels the wall for a straighter and more attractive wall. Apply Expo Perma Crete Adhesive to the wall prior to the leveling coat.
  • If the wall has been painted or sealed, metal reinforcement should be attached and a coat of plaster applied prior to the color coat.
  • Under normal conditions color coat will last 15 to 20 years.
  • Fog and Brush coat may be applied to blend new color coat finishes and revitalize old stucco colors. It is a portland cement base product and can be recoated with stucco color coat in the future.
  • Fog or Brush Coat may be applied after 24-hours or when the color has set. The color intensity may be field adjusted by using Base fog to lighten the color and Box color to darken the color.
  • On smooth finishes such as Santa Barbara, an acrylic additive should be added to the Fog or Brush Coat to improve adhesion to the stucco color coat.
  • Paint is a coating used to cover a stucco surface. Expo has a variety of paint products that can be matched to any stucco color. Proper preparation is the key to success when painting a stucco wall.
  • Paint may be applied 28-days after the stucco has been applied. The recommendations of the paint supplier should be followed.
  • If stucco color coat is to be applied to a painted wall, the paint must first be removed via sand blasting and the wall coated with Expo Perma Crete Adhesive for proper adhesion of the new color coat.
  • Acrylic finishes utilize paint technology with aggregates added that can be trowel applied.
  • Acrylic finishes may be applied over portland cement base substrates.
  • Mud, algae, and mold stains are removed using a mild solution of TSP (Tri Sodium Phosphate) and water. Using a plastic brush gently scrub the surface and rinse thoroughly. If stubborn stains persist try a solution of bleach and water (1-part bleach to 5-parts water) using the same brush and rinse technique.
  • Efflorescence (soluble minerals that appear on the surface of stucco) can be removed using a solution of 1-part vinegar to 5-parts water. Wet the surface prior to using the vinegar solution and thoroughly rinse the vinegar from the surface upon completion.
  • Expo Fog Coat may be applied after cleaning the wall to even the color.
  • This is a good option if you do not have gutters or if you do not have landscaping adjacent to the wall. Sealers are effective at repelling water born stains on new stucco finishes and help protect wall against water intrusion. Wait a minimum of 28 days before applying a sealer to newly plastered walls.
  • The sealer dissipates within five years.
  • If re-stucco is desired over a sealed surface the application of a bonder is necessary.
  • Under normal conditions bonder is not a required additive.
  • However if you plan to re-stucco over a previously painted, sand blasted surface, an adhesive such as Expo Perma Crete Adhesive should be applied at a rate of 250 square feet per gallon, depending on the texture of the wall surface. Bonded surfaces may alter the color of the stucco.
  • A certain amount of cracking in stucco finishes is normal. Smooth finishes, such as Santa Barbara Finish, reveal the cracks more readily than course textures such as a heavy lace finish.
  • Cracks that appear on the surface of stucco walls are usually caused by conditions within the wall structure. Some of these conditions include thermal expansion and contraction, ground movement, shear panel flexing, water penetration (causing framing members to swell), soil expansion and contraction, and a variety of other jobsite conditions.
  • Cracks may also appear due to drying shrinkage (wind checking or cracking). Newly applied stucco should be protected against rapid drying from high winds. In extreme conditions wet curing may be necessary.
  • Patching of stucco surfaces can be done with a variety of patching products. Large cracks can be filled and the wall fog coated. Patching of hairline cracks is not recommended as it will detract from the natural beauty of the stucco and will serve no useful purpose.
  • Hydration is the process by which cement cures. If water dries out too quickly during the curing process the stucco will dry soft.
  • Some of the causes of soft stucco include wind, high temperatures, and a dry substrate. Hot and windy weather may cause water to evaporate from new stucco too rapidly. The stucco does not hydrate properly and does not get hard. Walls may be moist cured to facilitate hydration. In addition, a dry substrate will suck moisture out of the color coat and stop the hydration process.
  • We are manufacturer's of stucco products and do not do the actual application of stucco. We would be happy to give you referrals for qualified contractors.
  • Color coat should be applied at a nominal thickness of 1/8" thick per coat
  • 3-1/2 gallons of clean potable water should be added to each 90-pound sack (1 cubic foot) of color coat. This will vary with humidity, temperature and the type of texture. Excessive water can result in a lower strength, irregular drying, and uneven color.
  • Variations in color are normal in stucco color coat finishes.
  • Excessive color variations may be the result of dissimilar substrates, variations in the suction, inconsistency of water content in mix, varying thickness of the finish, or weather conditions during and after application.
  • Expo Fog Coat may be applied to the surface to even the color on the stucco finish.
  • This is usually caused by extended exposure to moisture, which will eventually deteriorate the stucco.
  • The most common causes are:
  • Sprinklers hitting the wall.
  • Water sitting at the base of the wall and traveling up the wall in a wicking action, lack of weep screed at the bottom of stucco walls.
  • Improper drainage (water draining toward the wall).
  • Yes, stucco color coat may be successfully applied to a portland cement base substrate in an interior application.
  • However exterior stucco color coat will not stick to drywall or other non-cementicious surfaces unless an adhesive is applied to the surface prior to stucco application.
  • First try scraping the stucco off the concrete. Then try using a mild solution of TSP and water brushed onto the surface and rinsed thoroughly. If unsuccessful try a mild solution of vinegar and water (1-part vinegar to 5-parts water) using the same brush and rinse method. Caution: Vinegar may cause discoloration of the cement surface.
  • Expo Stucco does not recommend the use of accelerators in their finish products. However, on cold days, warm water used to mix the products will help speed up the set naturally.
  • Color coat should be applied to natural breaks in the wall in one application to avoid unsightly joint lines and discoloration.
  • The main difference is that one-coat stucco base coat is installed in one application to a thickness of only 3/8 inch minimum in lieu of three coat application which totals 7/8 inch thickness.
  • A variety of finishes, such as exterior color coat, acrylic, elastomeric, or paint may be applied directly to FibrewallTM One-Coat Stucco Base.
  • Advantages to one-coat stucco include the speed of application, allowing completion of the stucco installation in about one half the time required for a three-coat installation.
  • The fibers and proprietary components result in a product with good tensile, flexural and compressive strengths and the product is less prone to incur drying or shrinkage type cracking.
  • Fibrewall™ also improves on the quality of the mix, as all components are factory blended and packaged with only the prescribed amount sand added in the field.
  • The components include a weather resistive membrane; metal reinforcement and our fiber reinforced one-coat stucco.
  • The product may be installed over a wide variety of substrates including foam plastic insulation board; exterior gypsum sheathing, oriented strand board (OSB), exterior plywood, and almost any other code approved exterior sheathing. A substrate is always required; it is not designed for installation over open framing.
  • It may be applied to concrete masonry units with or without metal reinforcement.
  • It may be applied over Insulated Concrete Forms (ICF's) following the manufacturer's recommendations.
  • Yes, The product has been used for decades in various types of construction including single family and multi-family housing as well as commercial and industrial types of structures.
  • The installed cost, when considering the time savings, is comparable to traditional three- coat portland cement stucco.
  • No. FibrewallTM is a one-coat system that includes a weather resistive membrane, metal reinforcement and a fiber reinforced portland cement base coat.
  • FibrewallTM has a variety of fire ratings available to meet the needs in the construction industry. Consult our ICBO-ES report #4368 for the fire assembly that will meet your specific needs.
  • Yes, however since there are many types of construction and design utilized in multi- story structures, many variables would need to be evaluated by the design professional to determine the suitability for use.
  • FibrewallTM must be installed by an approved applicator or professional and is not designed for do-it-yourself use. We will be happy to give you names of qualified contractors as referrals.
  • One-coat stucco may be applied with a plaster pump or by hand trowel application.
  • Generally speaking, all cement-based products are subject to some cracking. Cracking is relatively minor and does not indicate failure of the product. The addition of fibers gives FibrewallTM exceptional crack resistance and resilience.
  • The product requires very little maintenance and is ideal for a wide variety of climatic conditions.
  • The need and use of controls joints and their location is dependent on a variety of design and structural issues. For these criteria the architect should be consulted.
  • Properly installed the product will cover mortar lines on masonry walls.
  • Generally a bonder is not required but certain types of block and brick and smooth concrete may require a bonder. FibrewallTM should not be installed over previously painted or sealed walls without the proper metal reinforcement.
