Mixing

Add one-and-a-half (1 1/2) gallons water to an empty, clean 5 gal. container. Slowly introduce one (1) 50 lb. bag of Bond Coat/Spray Texture Single Component Bag Mix (TX-SC) while mixing with an adequate drill equipped with a cage type mixer. A 450 rpm drill speed is recommended. Mix thoroughly for thirty (30) seconds to one (1) minute paying close attention to potential dry material on sides or bottom of bucket.

Application

Cover or mask all areas requiring protection with tape and paper so the material does not bond to unwanted surfaces. Dampen concrete before applying bond coat. Concrete MUST be damp with no standing water prior to bond coat application.

Pour mixed material onto the existing damp slab and broom or squeegee to approximately 1/16" thickness or less. Golf shoes or spikes are recommended to help prevent tracking or lifting material. Only apply bond coat in amounts that can be covered with stamp mix before drying. If the surface dries, use a pump-up garden sprayer or other means necessary to re-dampen the surface before applying bond coat.

NOTE: The amount of water required may vary slightly due to temperature and humidity. i.e. cool temperatures and/or high humidity requires less water for equal workability. Also, smaller jobs may only require mixing partial bags of bond coat.

STAMP COAT

Mixing

Mixing In a Bucket or Pail

Add between five (5) and six (6) quarts of water to an empty, clean 5 gal. container. Slowly introduce one (1) 60 lb. bag of Stamped Overlay Bag Mix while mixing with an adequate drill equipped with a cage type mixer. A 450 rpm drill speed is recommended. Mix thoroughly paying close attention to potential dry material on sides or bottom of bucket. Lumpy material will not gauge rake well and will result in an inconsistent application that could delaminate or present other problems. While continuing to mix, add DCF Color Pack as required for the desired color.

Mixing In a Mortar Mixer - (four-bag batch)

Start mixer. Add five (5) gallons of water to the mixer. Slowly introduce four (4) 60 lb. bags (one at a time) of PERLAM Stamped Overlay Bag Mix (ST-SC) allowing each to mix thoroughly. Continue to mix for a minimum of one (1) minute after the addition of the final bag. This consistency should be relatively thick allowing the material to mix well. Add DCF Color Packs as required for the desired color. Add up to one (1) more gallon of water to the batch as required for desired consistency.

Application

Pour stamp mix material directly onto the wet bond coat not exceeding an amount that can be reached and worked properly. Immediately gauge-rake to desired thickness. It is important to hold the gauge rake properly to achieve the correct thickness and coverage. Once the material is raked to a consistent thickness, smooth with a round-corner fresno trowel. Do not over-trowel material. Small trowel marks will disappear during stamping process. Pay close attention to maintaining the correct thickness at edges. Material applied to risers or other vertical surfaces is usually one-fourth-of-an-inch thick (¼") or less and thicker (drier) in consistency than normal.

Allow stamp mix material to set until material does not easily stick to your finger when touched. This drying time should range from thirty (30) min. to two (2) hours depending on thickness and weather conditions.

STAMPING

Using a pump-up sprayer, apply liquid release agent to stamps and to surface to be stamped. Cover an amount of material with liquid release that can be stamped within several minutes. If the liquid release has evaporated prior to stamping, it must be re-applied. Proper alignment of the first few stamps is critical.

Once a stamp platform is created, one or more people may work from its current location. Apply adequate pressure to the entire surface of each stamp producing a complete depression and proper texture. Continue running the stamps by carefully lifting the most previous stamp and placing it in sequence. If the desired texture is not achieved, re-set the stamp in the same orientation and apply proper pressure.

Use flexible stamping tools and touch-up mats against walls and columns or as required. Avoid creating a vacuum when lifting stamp tools by flexing corners or edges. Periodically check stamp alignment and adjust if necessary. Feather edged texture skins must be evenly hit with a tamper to ensure complete depression and flat overall texture. Touch-up stamps are generally used to provide texture on risers and vertical surfaces with free-hand grout joints cut after texturing. Risers may require stamping sooner than normal because the material is usually thinner and drier.

JOINT CLEAN-UP

Double lines and excess material in joints may be removed a few hours after stamping or sometimes the following day. Some stamp patterns with wide joints like Random Stone can be successfully cleaned up as soon as light foot traffic with socks is possible without disturbing the texture. A joint cleaning tool works best for wide joints where as a margin trowel or rigid putty knife is ideal for slate or cobble stone textures. Force knife directly through excess material while avoiding prying against adjacent stones. Use a blower or vacuum to remove loose material from surface. Re touch-up missed areas and repeat cleaning process.

ANTIQUING

Mixing

Mix one (1) part SelectGuard solvent sealer with one (1) part solvent in a wide-mouth container. Meter two (2) to three (3) teaspoons of DCF Antiquing Powder per gallon of mixed solution. Stir solution thoroughly with a drill equipped with a paint stirrer. When the solution reaches the desired color, carefully pour through a paint strainer into a pump-up sprayer. Coverage is approximately 200 ft2 per gallon.

Application

Cover or mask all areas requiring protection with tape and paper so that material does not stain unwanted surfaces. Apply liquid antiquing achieving the desired color and coverage. Use care to avoid bleeding under masking. The sealer solution will carry color to the low areas resulting in an aged appearance. Once the high points are dry enough to walk on, the surface is ready to receive two (2) coats of clear solvent sealer.

SEALER

Two coats of clear sealer are required to complete the project. The surface must be clean, completely dry, and at least 40°F during the sealer application. To apply with roller, use a solvent resistant, 3/4" nap. Apply one thin coat forcing the sealer into the low areas of the texture. Allow sealer to dry then repeat the process. A non-skid coat is recommended especially for outdoor use where wet conditions are inevitable. To apply with an airless sprayer, use a size 8/13 reversible tip and spray evenly onto the concrete surface. Allow first coat to dry completely and apply the second non-skid modified coat in the same manner.

CURE TIME

Allow twenty-four (24) hours before permitting foot traffic on sealed area. Allow seventy-two (72) hours before permitting vehicle traffic on sealed area.

CLEAN UP

Clean equipment and tools immediately after use as well as during use when possible. Water may be used to clean polymer modified cement from tools. Solvent may be used to clean up sealer or to clean polymer allowed to harden on tools.
