How to:

Spray The Shamrock With Flex Seal Colors

Before using Flex Seal, please read all the directions carefully.

In a well-ventilated area, lay down a tarp and place the shamrock on top. Holding the Flex Seal® Green, begin to spray 8” to 12” inches from the surface. Use even sweeping motions to cover the entire surface of the shamrock. Once completely covered and you’re happy with the outcome, set to dry.

Design Pattern On Wood With Bottle Caps

Next, arrange and position the bottle caps, top side down, onto the piece of wood until the wood is fully covered. You can create a design or place the bottlecaps in rows, whatever makes you happy. To help remember the pattern and spacing, snap a picture. Then, remove all the bottle caps from the wood plank.

Glue Bottle Caps To Wood

Now it’s time to secure the caps with Flex Glue Clear.

First, unscrew the nozzle of the Flex Glue Clear. Using a pair of scissors or a razor blade, cut an opening large enough to ensure the glue is easily dispensed. Next, apply a liberal amount of Flex Glue Clear to the top side of each bottle cap, and recreate your chosen design onto the wood. Make sure to apply firm pressure continuously for a minimum of 10-30 seconds for instant grab to take hold. Repeat this process, gluing all the bottle caps in place until the design is complete.

Flex Tip: Even though the instant grab will take hold in 10-30 seconds, there is still be plenty of time to slide and rearrange the bottle caps if needed in before the glue fully sets, which is perfect for this project!


More tips on using Flex Glue


Create Bottle Cap Risers

Use Flex Glue Clear to build “bottle cap risers” which will hold the shamrock away from the wood base to create a more dynamic effect. To do this, glue the bottle cap tops together like a sandwich. Make sure to press them together firmly for 10-30 seconds for instant grab to take hold. Create 3 sets of bottle cap risers.

Flex Tip: For an even more dramatic effect, create another layer!

Glue Risers To Wood Base

First, center the shamrock on the wood base. Then, remove to position the bottle cap risers so they’ll be hidden by the leaves of the shamrock, once it’s glued into place. Apply a generous amount of Flex Glue Clear to the bottoms of the risers and glue in place.

Glue Shamrock To Risers

Next, apply Flex Glue Clear to the top of each bottle cap riser. Position the shamrock into place, and apply light pressure until Flex Glue Clear’s instant grab takes hold.

Add Twine And Hang

Thread twine through the top holes of the wood base and tie off each end in a knot to hang. Allow curing for 24-48 hours before hanging.
