This is the exterior wall construction method for the brick tile "CAN'BRICK" (MT-BOND-FLEX elastic adhesive laying method).
Applicable substrate: Siding/concrete/block/russ mortar
By using the elastic adhesive (MT-BOND-FLEX), it can be used on siding substrates that cannot be applied using wet construction methods with resin mortar. Even with conventional mortar substrates, it is more elastic than wet construction methods with mortar, so it can follow the movement of the substrate and suppress the occurrence of cracks.
*Since the joints are filled with mortar after the adhesive has hardened, the construction period is longer than with conventional wet construction methods.
2. Applying adhesive
Apply the elastic adhesive (MT-BOND-FLEX) to the base using a 6mm toothed trowel.
The area you paint at one time should be the area that will allow you to finish laying the bricks within the allotted time.
◎ If the effective bonding area is 70% or less, use an 8mm toothed trowel to increase the amount of elastic adhesive (MT-BOND-FLEX) applied to the base, or increase the amount of elastic adhesive (MT-BOND-FLEX) applied to the back of the brick.
3. Attachment (Improved Pressure Bonding Method)
Apply elastic adhesive (MT-BOND-FLEX) to the entire back surface of the brick until the feet (tentacles) are no longer visible. Press the elastic adhesive firmly until it overflows.

◎To check the adhesion of the Elastic Adhesive (ME-05) during application, peel off several sheets every 2m² and check that the Elastic Adhesive (ME-05) is attached to more than 70% of the back side.
◎ If the effective bonding area is 70% or less, use an 8mm toothed trowel to increase the amount of Elastic Adhesive (ME-05) applied to the base, or increase the amount of Elastic Adhesive (ME-05) applied to the back of the stone.
◎ Any adhesive adhering to the surface of the finishing material should be wiped off with a cloth soaked in thinner or similar before it hardens.
1. Surface preparation
A. In the case of concrete, block, or raspberry base...
After inspecting and cleaning the base, apply an adhesive enhancer (such as Tilement EV-300) with a roller. In the case of a rasmol base, allow sufficient curing time to ensure that it is completely dry and has minimal unevenness before applying the adhesive enhancer.
B. In the case of wooden base...
Apply waterproof paper and use it as a mortar base, or create a mortar base on top of a mortar board. After allowing sufficient time for curing, carry out the same work as in (a).
※point※
◎ Avoid carrying out installation in rainy weather and carry out on a sunny day.
◎ When carrying out work during cold seasons, do not carry out work when the temperature is below 5°C or if it is expected that the temperature will drop below 5°C during the curing period after work.

4.Curing
Allow sufficient curing time for the elastic adhesive (MT-BOND-FLEX) to harden.
5. Joint finishing
Fill the joints with the special joint material MT-MEJI using a joint bag, etc. After filling, roughly press down with a joint trowel. Check that it covers at least 1/2 the thickness of the brick and your desired finish (see joint finish), and fill in any gaps with a joint bag, etc.
※point※
◎ Don't worry if the joint trowel leaves uneven marks as you finish the job, and finally use a brush or scissors to scratch the joints in places to make them look weathered.
6. Protection and water absorption prevention treatment
Avoid ventilation and direct sunlight, and protect the stone by covering it with a sheet, etc. Allow the stone to cure for a sufficient period after application, and make sure it is completely dry. Then thoroughly brush off any dust on the stone surface and in the joints.
After that, apply the penetrating water absorption prevention agent "REPEL･S" using a sprayer, brush, roller, etc.
◎Since CAN'STONE is a secondary cement product, acid washing is strictly prohibited.
