Elastic joint material that does not require mixing work during construction due to its liquid nature.

A new elastic joint material that has never been seen before. Being a single-component product, there is no need for mixing during application. It has received high praise from many customers for its excellent workability. It possesses moderate flexibility, follows the vibrations of the floor, and prevents joint cracking and joint lifting. The rich variety of six colors is also one of its attractions. ◆Features◆ ◎Speedy... Significantly easier to apply compared to conventional products. 　→ As it is a single-component product, there is no need for mixing, which shortens the application time. There are also no complaints about color unevenness due to poor mixing. ◎Easy... Easy to wipe off. Residue can be removed with water. 　→ If there is residue, two-component products harden, making them difficult to wipe off, but "Flex Color" can be easily wiped off. ◎Satisfaction... Achieves high elasticity compared to conventional two-component products. 　→ Compared to typical mortar joint materials and traditional two-component elastic joint materials, it is less prone to joint lifting. ◎Ecology... No waste and consideration for the environment. → Leftover joint material can be used at another site as long as it hasn't dried out. *Please avoid mixing with new joint materials. ＝＝If you would like a sample, please contact us＝＝

During this time, protect the joint with sheet covering to prevent damage or debris from adhering. 【Shelf life】 ● 2 years from the date of manufacture (manufacture date label attached to the lid) ● For products produced overseas, please use within 1 year of delivery.
