This is the exterior wall construction method for the stone masonry style imitation stone tile "CAN'STONE" (elastic adhesive application method).
Applicable substrate: Siding/concrete/block/russ mortar
By using ME-05 (adhesive for interior and exterior wall imitation stone tiles, Can'Stone), it can be used on siding bases that cannot be applied using wet methods with resin mortar. Even with conventional mortar bases, it is more elastic than wet methods with mortar, so it can follow the movement of the base 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.
1. Surface preparation
A. In the case of concrete, block, or raspberry base...
下地の点検を行い清掃を行って下さい。ラスモル下地の場合は、十分な養生期間をとり完全に乾燥していること、不陸の少ないことを確認して下さい。
B. In case of siding board base...
Make sure the joints are firmly secured and the base is prepared to prevent movement.
Apply butyl joint tape to joints and corners.
*Recommended thickness of siding board: 14mm or more
※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.
2. Preparation for pasting
Take out the stones from the multiple cartons and place them temporarily on the work area. Create an overall image and then start pasting.
3. Applying adhesive
Apply the elastic adhesive (ME-05) to the base using a 6mm toothed trowel.
The area you paint at one time should be the area that you can finish applying the stones to 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 (ME-05) applied to the base, or increase the amount of Elastic Adhesive (ME-05) applied to the back of the stone.
5.Curing
Please allow sufficient curing time (at least one day in summer, at least three days in winter) for the elastic adhesive (ME-05) to harden.
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 stone and your desired finish (see joint finish), and fill in any areas that are lacking 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.
7. 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.
4. Paste
Use a spatula or similar tool to apply dots of adhesive to the back of the stone.
Alternatively, apply elastic adhesive (ME-05) to the entire back surface of the stone until the feet (octopus feet) are no longer visible. Press firmly until the elastic adhesive overflows.
※point※
◎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.
