Characteristics/Advantages
Tough Coat offers excellent crack-bridging properties and forms an elastomeric membrane that cures aerial moisture to a flexible, rubbery coating. It is a single-component, ready-to-use product that makes application easy by brush, airless spray, or roller. The coating is economical, abrasionresistant, hydrolysis-resistant, and root-resistant as part of a built-up system. It is resistant to mild acids, chemicals, industrial environments, and UV exposure. Additionally, it is low in VOCs and eco-friendly.
Application
Apply a primer coat of Tough Coat diluted with 50% clean water, which will cure in 2-4 hours depending on atmospheric conditions, with an approximate consumption of ~0.25 kg/m² using a hard brush, roller, or airless spray. Apply the first Coat of approximately 0.50 kg/m² of Tough Coat, then apply Non-woven Geotextile fabric / Pro Membrane on the surface and ensure no bubbles or creases. Overlap adjacent Non-woven Geotextile fabric / Pro Membrane by a minimum of 50 mm and allow this Coat to dry for at least 24 hours, depending on atmospheric conditions. Apply a second coat of approximately 0.50 kg/m² to achieve the required film thickness. Avoid spoiling the dry surface while walking on it while applying the material. The material should be applied within the workable time. Full curing may take up to 7 days, depending on temperature and humidity.
