Materials required: Vertical Stamp Mix, Flexy-Bo Primer & Bonder, RockMolds Integral color, RockMolds Trowel, Liquid Releasing, RockMolds – Weatherwood 3pc set, RockMolds Tuck Point Trowel, RockMolds Stone Color Stains, RockMolds Stone Sealer.
1. The existing substrate is a set of concrete block columns. Vertical stamping is a perfect application to veneer these columns with a natural wood look.
2. First Flexy-Bo Primer & Bonder is rolled onto the concrete wall. Allow to tack up for 30 minutes. Then apply a thin 1/8″ thick scratch coat of S-Type mortar with a Mini Pool Trowel, and scarify the surface.
3. After the scratch coat has been allowed to dry, a ½” thick texture coat of a Vertical Stamp mix is troweled up with a Mini Pool Trowel.
4. A liquid release is then applied to the troweled out texture coat, and to the wood stamps. This allows an impression without sticking. We use RockMolds – Weatherwood 3pc set set for the majority of our wood vertical stamping.
Tip #1: It is important to immediately stamp after a batch of Vertical Stamp Mix has been applied, as the detailed texture will be captured with a softer surface.
5. Continue the application of a batch of Vertical Stamp Mix, and stamping out immediately behind.
Tip #2: Rotate your stamps when stamping so the grains are mixed.
6. After the vertical stamp mix has sufficiently firmed up, usually withing 4-6 hours, the wood can be accented by carving out. A RockMolds Tuck Point Trowel works great.
Tip#3: A chip brush dipped in water may be used at this time as well to clean up the wood.
7. Let your wall cure 24 hours minimum. Hose off any loose debris.
8. Color the wood with RockMolds Stone Color Stains. Start with lighter colors, and layer in the darker colors until a certain look is obtained. You can always go darker!
Tip #4. Use multiple quart size spray bottles to apply different colors of stain, mixing the colors wet on wet so they blend together. Use a concrete sponge to blot the surface for any runs.
9. Seal the wood with RockMolds Stone Sealer. This will give the most natural appearance to the wood, without a sheen.
Tip #5: Seal every 2 years to refresh the color and protect your investment!
