Environmentally friendly, safe water-based rubber asphalt waterproofing material and substrate adjustment material. It can be applied to wet substrates and work can be done immediately after removing the existing waterproof layer!
"O-PHALT BASE" is a temporary waterproofing material suitable for interim waterproofing from the removal of the existing waterproof layer to the installation of new waterproof materials in waterproof renovation work. Since "O-PHALT BASE" is asphalt-based, it exhibits excellent compatibility and adhesion with other asphalt-based waterproof materials. It can also be used as a substrate adjustment material after the removal of the existing waterproof layer. It can be used even when the substrate is damp, and due to its excellent adhesion to concrete and mortar, it can be applied immediately after the removal of the existing waterproof layer. Its quick-drying properties contribute to shortening the construction period and prevent rainwater intrusion during the work until the new waterproof material is installed. 【Features】 ■ Particularly excellent adhesion to concrete, mortar, and asphalt-based waterproof layers ■ Water-based emulsion type, allowing application to damp substrates ■ Excellent quick-drying properties enable immediate subsequent work, thus shortening the construction period ■ Uses environmentally friendly materials that do not contain environmental hormone formaldehyde ■ Can be used as a temporary waterproofing material, substrate adjustment material, and even as a main waterproofing material simply by changing the mixing ratio *For more details, please refer to the PDF document or feel free to contact us.
