Using a Grout Bag and Tuck-Pointing Trowel for Larger Joints

1/8” mortar joints can be attained by applying a bit of mortar on the edges of the TOP and SIDES of each piece of veneer BEFORE attaching it to the BrickWood Box, but larger joints such as 1/4” and 3/8” joints will likely need to have the mortar squeezed into the joints with the use of a GROUT BAG and a TUCK-POINTING TROWEL. It is important to determine the thickness of your joints prior to attaching the veneer so you know which size tuck-pointing trowel that you will need to use or purchase.

Cut a 1/4”–3/8” hole in the tip of the GROUT BAG. Fill the bag with mortar then twist the top end of the bag – this will force the mortar out of the bag and into the joint openings. Squeeze the mortar on 2 or 3 pieces of veneer at a time.

Press the mortar into the joint with a TUCK-POINTING TROWEL. As the mortar begins to harden, BENCH BRUSH the joints to remove loose mortar – it should crumble like sand. If it smears or falls out, allow the mortar a bit more curing time.

After all the veneer is mortared into place and you have brushed away any mortar clumps, wipe the mortar residue with a damp CONSTRUCTION SPONGE. DO NOT use so much water that it runs. Rinse the sponge in a bucket of clean water after each wipe.
