Aristex is packaged and shipped in 5-gallon pails and 55-gallon drums. An MSDS is shipped with each order and we recommend that a copy be kept available at the job site.


Proceed with application only when conditions will permit work to be performed in accordance with good construction practices. This product is to be applied directly to clean, dry sound surfaces, both drywall and concrete. Do not apply this product when the surface is wet or if ambient temperatures are below 45° F or expected to drop below 45° F within a 24-hour period.


The surface must be properly prepared, cleaned and repaired before any coating may be applied to avoid blistering, peeling or delaminating and assure proper adhesion. Thoroughly clean the surface to remove all dirt, loose granules, and contaminants (oil, grease, solvents, etc.) that may interfere with proper adhesion. For concrete, pressure wash with a mix of water, a biodegradable cleaner and bleach, scrub with a broom,

thoroughly rinse with clean water, and allow to completely dry. Thoroughly inspect and test concrete surfaces for any moisture before proceeding. The type and degree of surface preparation will determine the success of the finished project. Aristex will not fill voids in substrates nor hide imperfections. Do not apply directly to concrete surfaces with a pH greater than pH 9.


Mix thoroughly for 5 to 10 minutes prior to application at low speed to evenly disperse contents that may have settled during shipping or storage. Rolling or shaking pails or drums will not properly mix coating. DO NOT USE A DRUM HEATER or open flame or any other source of open heat. DO NOT THIN. DO NOT ALLOW ARISTEX TO FREEZE. In hot weather, opened containers may form a surface skin in the drum. This must be removed before mixing or spraying so as not to gum up spraying equipment or cause a lumping in the coating. All products have a shelf life. Do not open or prepare a container until ready to apply. Use with adequate ventilation and adhere to all applicable safety and equipment practices. Ground electrical tools, machines and equipment in accordance with the National Electrical Code.

Coverage rates are estimates only. Actual coverage may vary depending upon the type, porosity and condition of the surface. Test actual coverage for each project.


Inspect surface, take photographs and detail job requirements for problem areas. Do not apply coating until unsatisfactory conditions are repaired. Thoroughly clean the surface to remove all debris, dirt, flaking, loose granules, chalking and contaminants (oil, grease, solvents, etc.) or anything else that may interfere with proper adhesion. Concrete that is cracked or brittle must have protrusions, cracks and splits repaired. Pressure wash concrete with a mix of water, a biodegradable cleaner and bleach, scrub with a broom, rinse with clean water and allow to dry completely. The surface must be thoroughly inspected for any moisture on or within the surface. Only apply Aristex to clean, dry, sound surfaces.

New Construction:

Concrete must be cured and free of excess moisture prior to the application of this coating. Allow new concrete and stucco to cure 30 days and mortar joints to cure 15 days. Concrete or mortar with high lime content can cause excessive alkalinity resulting in coating failure. Check the pH of the surface with an Insta-Chek Surface pH Pencil or other measuring device. Surface alkalinity is measured in pH with pH 7 being neutral. If the surface pH exceeds pH 9 (blue), treat the surface with a 5% muriatic acid and water solution, rinse with clean water and let dry.

Concrete Block and Other Porous Surfaces

New or uncoated concrete block may require an application of block filler prior to application. Back roll the base coat and first coat of the finish system to force out any entrapped air and to increase adhesion.

Previously Coated Surfaces 

Pressure wash the surface with hydro-spray equipment (1500-2000 psi) using a maximum 25° tip to remove all dirt, flaky paint or coating, mildew, chalk or other foreign contaminants. Let it dry completely. If needed, apply a masonry conditioner to tie down any chalking residue.                                                                                      

Surface repair:

Repair any cracks and surface imperfections prior to application.

Hairline cracks

Aristex will bridge all existing hairline cracks with no additional preparation necessary.

Small to medium cracks (less than 1/8")

Work filler into the crack with a broad knife. There are elastomeric fillers that will remain flexible.

Medium to large cracks (1/8" to 1/4")

Work filler into the crack with a broad knife. Allow it to dry. Apply a second coat if any shrinkage is evident. Apply in a thin coat over the prepared crack and apply a single layer of Reinforcing Tape. Immediately after the tape has adhered to the first coat, apply a second coat to smooth to embed the tape. Feather the edges to ensure a uniform surface.

Surface imperfections

Can be patched by following the above procedures for medium to large cracks.


Aristex Fine, Medium and Coarse must be applied using air-powered spray equipment only. Do not attempt to apply fine, medium or coarse textures with a brush or roller. Use the product directly from the container. Do not thin. Mix thoroughly with a power drill and mixing blade prior to use. Apply to properly prepared surfaces at the recommended spread rate. Failure to apply the product at recommended rates may result in poor performance or possible failure. Backroll the coating into porous surfaces for increased adhesion and to eliminate pinholes.
