OR599W - Mini-Brick Mortar, White, 16 Ounces

When creating a simple straight line brick pattern, glue bricks to surface beginning at the bottom of your project (i.e., foundation, chimney or fireplace base).
For more complicated designs and patterns, it's a good idea to create a drawing of your plan to use as reference as you install the bricks.
Glue bricks to surface using a good quality adhesive (such as Aleene's, Multi-Grip, Magna-Tac, or Grrrip).
Be sure to keep horizontal lines level along each course.
Have wood strips available to use as spacers for each row of bricks as well as between brick sides (1/32" to 1/16" thick stripwood would work good for this purpose, depending on your preferred mortar joint thickness).
Be sure that you alternate each course to form the typical brick pattern found in building construction.
Coat bricks with a non-yellowing polyurethane or a clear sealer.
Let dry overnight.
With a foam brush push mortar into spaces between bricks.
Gently wipe off excess mortar with a damp sponge.
Let bricks and mortar sit for a minimum 24 hours before anything is placed on or glued
to surface.
