Clean the surface with a suitable detergent, rinse thoroughly with clean water, and once the surface is perfectly clean and dry, apply a first coat of the product manually using an uncolored cotton cloth, ensuring even application and avoiding irregular absorption. It can also be applied with a brush or a fine rectangular sponge, taking care to avoid uneven absorption and to spread the product uniformly. It is recommended to apply a small amount of product and spread it thoroughly to avoid sticky surface residues. The treated surface is walkable after 24 hours. Full protection becomes active after 24\u201348 hours and is fully achieved in about 5\u20137 days, depending on environment humidity.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"vc_row-full-width vc_clearfix\"><\/div><div class=\"vc_row wpb_row vc_row-fluid vc_custom_1657700496601 vc_row-has-padding-top vc_row-has-padding-bottom vc_row-bg-position-top\"><div class=\"wpb_column vc_column_container vc_col-sm-6\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><div class=\"vc_row wpb_row vc_inner vc_row-fluid vc_row-bg-position-top\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div class=\"wpb_text_column wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p><strong><span style=\"font-size: 18px;\">PRECAUTIONS<\/span><\/strong><\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t<div class=\"wpb_text_column wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p>Do not apply the product on too hot surfaces or under direct sunlight.
