Achieving the Most Attractive Finish with Textured Elastomeric Coatings

As with any textured coating systems, achieving the best outcome of a textured finish depends upon several factors. Selecting the right textured coating for the job is a critical step. Most textured coatings are made for application on masonry, stucco, cinder block, and concrete. Some can also be applied to properly prepared wood, and metal. In addition, textured coatings are also made for a variety of commercial (high rises, museums, hotels, tunnels, for example) and residential locations, and in rehab and new construction. These coatings are extremely versatile. Textured coatings offer application and performance advantages in interior and exterior locations, and in all types of weather.

Once the right kind of textured coating has been selected. Surface preparation is the next key step in achieving excellent product performance. In general, any surface that will be coated with a textured finish must be free of all loose dirt, oil and mildew. In addition, efflorescence and chalk, which could affect product adhesion, should be cleaned away. Loose pieces of surface debris should also be removed. In most cases (except where noted by the manufacturer) new concrete should be allowed to age 30 days before a coating is applied. To insure a continuous coating application, all cracks, gaps and joints should be filled with a compatible compound recommended by the manufacturer. Applying an appropriate primer, if specified by the manufacturer, is the final step before the textured coating is applied.

Before Texcote Elastomeric Smooth

How the textured coating will be applied is another consideration. Textured coatings come in a wide variety of profiles from smooth high build systems to textured coatings that are filled with textured material. In most situations, textured coatings can be spray applied with specialized equipment designed to spray textured paints. However, textured coatings can be applied with a brush or roller in some areas. Special attachments to spray equipment may be necessary for some textured coatings, so be sure to carefully look over product literature for application recommendations. Some textured coatings can even be manipulated by hand with masonry or stucco tools after the coating has been sprayed on to the surface.

Finally, equipment clean up will be determined by the type of coating used: paint thinners are effective with solvent-based systems, and soap and water is suitable for water-based products.

Durable and Decorative Textured and Smooth Elastomeric Coatings

Textured coatings are gaining popularity over other products that have been used in the past. In many installations like offices, hotels and hospitals, textured coatings have replaced vinyl wall coverings because of their durability and resistance to mold and mildew. Vinyl wall coverings create a vapor barrier that traps moisture. As a result, mold and mildew formation under these wall coverings is not uncommon. However, textured coatings are made to "breathe" which allows moisture to escape. Another advantage offered by many textured coatings is their low odor and easy application. In most cases, applying these coatings is no different than other architectural finishes. Textured coatings are extremely durable and scrubbable, which makes these coatings an excellent choice for not only residential, but high traffic areas like auditoriums, lobbies and school buildings.

After Texcote Elastomeric Smooth

In addition to the many interesting patterns and designs that can be created with textured coatings, a wide range of color choices is also possible. Blending in with the design scheme and decorating materials used on a project is not a cause for concern.

It is important for the contractors, owners, architects and specifiers to realize that these textured coatings are designed for high performance and far exceed the functions of typical masonry paints and stucco. They will provide many years of waterproofing, extended surface life and decorative treatment.

Application Procedures for Texcoating for smooth and textured finishes

Trenching to the foundation

Masking and covering all areas subject to overspray

Water blast (3500-4000 psi) or sand blasting to remove loose stucco and peeling paint

If efflorescence is present, chemically treat the surface

Repair stucco surfaces with cement patching compounds and water proofing cement as necessary

Allow surfaces to dry at least 24 hours before application of primer and sealers

Apply primer/sealer at rate of Ľ gallon per 100 square feet

If efflorescence has been a problem, apply an efflorescence inhibiting masonry primer

Allow primer and sealers to dry per manufacturer instructions

Apply textured coatings at manufacturer recommended rate: approximately 2˝ to 3 gallons per 100 square feet at approximately 500 psi to desired texture and pattern (if smooth: spray and back roll)

Textured coatings are available in standard and custom colors

Trim painting process:

Thoroughly scrape and sand all wood and metal surfaces
Glaze windows as necessary
Replace or repair damaged wood
Apply full prime coat to all surfaces to be painted
Apply second prime coat to all patches and repairs
Apply finish coat by hand brushing

(Manufacturer specification and MSD sheets available on request)

Textured Coating Warranties

Most manufacturer warranties are similar and contain some or all of the following:

Upon completion of Texcoating application in accordance with the manufacturer recommendations, manufacturer will extend its limited residential or commercial warranty for product replacement as a result of defects in the material.

Manufacturer must be notified prior to application of textured coating. Textured coating application must be in compliance manufacturer's recommended installation procedures.

Manufacturer shall have no obligation to provide or participate in labor costs associated with effecting repairs.

No particular maintenance is required, however, should the product become soiled, simply clean with light water pressure and mild detergent.

If moisture sources or efflorescence is present, water sources must be located and eliminated prior to coating application. This is not the responsibility of the coating applicator but it is the responsibility of the property owner to do so. This work should be done by a general, building contractor.

Possible Sources of Moisture

Missing or defective rain gutters and down spouts

Improper grading of lot (soil, slab and walkways pitching toward the structure, allowing water to accumulate at the foundation)

Leaking garden spigots or sprinklers spraying on the structure, accumulating at the foundation

Improper lot drainage

Moisture is generated by cooking and bathing, which works its way into the attic. If the attic is not properly ventilated, the moisture can eventually cause problems such as delaminating of roof sheeting, water streaking, staining, mold and mildew, dry rot and; flaking, peeling and bubbling paint on interior and exterior walls.
