This is the interior wall construction method for the brick tile "CAN'BRICK" (MT-BOND adhesive laying method).
Applicable substrates: gypsum board (plasterboard) / calcium silicate board / structural plywood / mortar substrate
*Areas not exposed to water
1. Surface preparation
Clean the base surface. Check that the base is firmly fixed and that there are no unevenness in the joints of the boards, etc.
2. Applying adhesive
Apply the special interior wall adhesive (MT-BOND) to the base using a trowel with teeth of about 6 to 7 mm, squeezing it in, then close off the teeth to adjust the thickness to about 3 to 5 mm.
The area to be painted at one time should be the area where the bricks will be laid within approximately 40 minutes of open time, or within 1 MAIKO KANNO².
3. Attachment (Improved Pressure Bonding Method)
The back of the brick is slightly uneven, so apply MT-BOND to the extent that the legs (octopus legs) of the brick are no longer visible. Attach the brick by kneading it, and press MT-BOND fully into the joints so that it fits the entire back of the brick until it overflows.
※point※
◎To check the adhesion of the special interior wall adhesive (MT-BOND), peel off several sheets every 2 m2 and work while checking that the special interior wall adhesive (MT-BOND) is attached to at least 70% of the back side. If the effective adhesion area is 70% or less, use an 8 mm comb trowel to increase the amount of special interior wall adhesive (MT-BOND) applied to the base or increase the amount of special interior wall adhesive (MT-BOND) applied to the back side of the brick.
4. Joint finishing
Use a slightly damp brush to smooth out any excess joints to give them a natural look.
※point※
If there is not enough adhesive in the joints, it may cause peeling.
5.Curing
Avoid direct sunlight and protect the product with a sheet or similar.
Allow sufficient time for the adhesive to harden.
To express better designs
MT-BOND is a one-shot adhesive and joint material, but if you would like to use a mortar joint (MT-MEJI) finish to achieve a better design, please refer to the following.
6. 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 trowel leaves uneven marks, just finish the job, and finally use a brush or scissors to scratch the joints in places to make them look weathered.
*For exteriors or areas exposed to water, please refer to the sections on elastic adhesive installation or wet installation.
7. Cleaning
Be sure to thoroughly brush away any dust from the surface of the bricks and in the joints.
If cleaning is not done properly, it may stain your clothes.
In tile work, it also includes the design of the joints (creating nuance).
Once completely hardened, please have a cleaning company thoroughly brush away any initial dust from the rough joints.
◎Since CAN'BRICK is a secondary cement product, acid washing is strictly prohibited.
