Description
● 100 percent acrylic-based textured finish.
● Dirt Pick-up Resistance (DPR): The surface of the finish hardens and does not
soften again under heat. The non-tacky surface provides high resistance to
accumulation of dirt, mold, and pollutants.
Uses
Exterior or interior finish coat over:
● Properly prepared masonry, stucco, and concrete surfaces.
● Interior application over drywall, plaster, or properly prepared masonry or
concrete.
Composition
● Binder base: 100 percent acrylic polymer with surface-hardening property.
● Aggregate: Pure crushed marble, rust-free.
● Water-based: VOC-compliant.
● Pigment base: Titanium dioxide.
Colors
● 40 standard colors are available. See the LaHabra Acrylic Finish color chart
for details.
Packaging
● LaHabra Acrylic Finishes are available in 65 lb.(29.5kg) pails.
● Liquid color is available in 4 oz. and 8 oz. bottles.
Coverage
Depending on the condition of the substrate and method of application, approximate coverages are:
- Sand Smooth:
Aggregate size: 0.5mm
Coverage varies with texture desired
- Sand Medium:
Aggregate size: 1.0mm
150-165 sq. ft. (14-15 sq. m.) per pail.
- Sand Coarse:
Aggregate size: 1.5mm
90-130 sq. ft. (8-12 sq. m.) per pail.
A. Surface Preparation
- Remove surface contaminants such as dust or dirt without damaging the substrate.
- For previously painted surfaces, all loose and chalking paint must be removed and glossy surfaces dulled.
- New concrete and masonry must be clean and cured a minimum of 28 days.
- Check concrete surfaces for alkalinity and treat. Any form-release agents or bond breakers must be removed.
- Uneven concrete or masonry can be leveled with Stucco Level Coat or other suitable, compatible product.
- For interior drywall, prepare as for painting.
- Prime with LaHabra Acrylic Primer.
- For additional options, contact ParexLahabra Technical Services Department.
B. Mixing
- Use clean equipment for mixing and preparation.
- Stir to obtain a homogeneous consistency using a heavy-duty 1/2-in. (13mm) drill with a rust free paddle at 400-500 rpm. Avoid air entrainment.
- Add liquid color to the pail of finish. Make sure all of the color is added by rinsing out the color vial with water (1/3 of the vial's volume) into the pail.
- Add the amount of water needed to achieve finish texture. To avoid color variations, add the same amount of water to each pail of finish as indicated on product pail.
C. Application
- Read the entire label before using this product
- Always maintain a wet edge and work to corners or joints. For best color consistency, use finish with the same batch number within a wall section.
- Keep container closed when not in use.
- Use a clean stainless steel trowel and apply a uniform coat the thickness of the largest aggregate size of the finish.
- Sand Smooth Finish:
- Optional: Level stucco brown coats with Stucco Level Coat and let dry prior to finish application.
- Sand Smooth Finish cannot generally be floated. Texture will be "as trowelled."
- Sand Smooth Finish can be trowelled smooth to simulate the texture of limestone.
- For smoothest application, apply in two tight coats. Allow first coat to dry enough that it will not be disturbed during application of the second coat. When second coat is partially dry, trowel to desired smoothness. Light, consistent misting with water during smoothing will increase smoothness. Variations in color tint and smoothness should be expected.
- Sand Medium and Sand Coarse Finishes:
- Use a clean plastic float or stainless steel trowel. A plastic float will roll the large aggregates more than a stainless steel trowel. Continuously clean and dry the plastic float or steel trowel while texturing. Use consistent pressure and motion to achieve the desired texture.
- Spray application: To achieve consistent texture, spray application must use consistent motion, pressure, distance and spray angle. A job-site mock up for spray application is advised.
Limitations
- Always wear proper safety equipment when mixing and/or applying this product.
- Protect adjacent materials during application and protect the applied material from weather and other damage while material cures.
- LaHabra Acrylic Finish must not be used on exposed horizontal exterior surfaces. Minimum slope is 6 in 12 inches (150 in 300mm) (27°), maximum run of slope is 12 inches.
- Do not use below grade.
- Ambient and surface temperature must be 40°F (4°C) or higher during application and drying time. Provide supplemental heat and protection from precipitation as needed.
- Use only on surfaces that are sound, clean, dry, unpainted, and free from any residue that might affect the ability of the finish to bond to the surface.
- Application in direct sunlight in hot weather may adversely affect aesthetics.
