Gumi Bricks Installation

1. Unpack all the Gumi Bricks & layout on the floor in a random combination so the colour tones & textures are mixed. Remember Gumi Bricks is hand crafted with all the bricks being cut by hand & painted by hand so there will be slight variation in size & a modulation of colour tone throughout the collection “this is the beauty of Gumi Bricks”. We suggest to create the scale of the installation on the floor first. Once you are happy with the tonal mix then the tiler can start to install the bricks from the bottom row and work their way up the wall.
2. Option A Application (Wet)
   • Wetting exterior walls
     Dampen concrete, masonry or stucco wall surfaces with water prior to the application of the Gumi Bricks.
   • Wetting the Bricks
     The back of the stones should be completely damp, but free from surface water at the time application. If using a modified mortar, follow manufacturer’s recommendation regarding wetting of stones and scratch coat.
   • Mortar & weather conditions
     If bricks being applied in hot or dry weather, the back of each peace should be moistened with a fine spray of water or a wet brush to adequately prevent excessive absorption of moisture from the mortar. If being installed over concrete, masonry or scratch coat substrate, the substrate surface area should also be dampened before applying mortar. Surface should appear damp but free of surface water.
3. Option B Application (Dry)
   On some interior projects, the use of masonry adhesive offers a fast and easy alternative to mortar.
   Place adhesive as per adhesive manufacturer’s instructions on the back of each Gumi Brick perpendicular to grooves on brick. Press and wiggle brick into place on wall surface until they bottom out. Set bricks level and plumb, completing one row at a time.
