・Please wait until the substrate is completely dry before use. In particular, when applying to plaster or mortar, be sure to allow it to dry completely before use; otherwise, the water glass and slaked lime will react, causing efflorescence to occur immediately.
・Be sure to dilute the product 2:1 before use. The undiluted solution is too viscous and will not penetrate effectively.
・When applying to old walls, the required amount varies depending on the degree of deterioration; however, even if you apply the 2:1 diluted solution three or more times, it will not penetrate the wall, and the effectiveness will not change. Please note that if it does not penetrate, a glassy film may remain on the surface, which could result in an unsightly appearance.
・Walls with dense surfaces, such as plaster, will develop a sheen, so this product cannot be used as a finish. However, it can be used to reinforce plaster as a base coat (when applying a new finish).
