PURSELF 201 is a polyurethane based, two component, low viscosity, solvent free, elastic, self-levelling coating and waterproofing material.
Preparation of Substrate
Application surface must be cleaned off from the contaminant such as dirt, dust, rust, oil etc. Application surface must be scraped to be ready for application. Before the application on an asphalt surface, the surface must be prepared mechanically using abrasive blast cleaning or scarifying equipment to expose at least 50% of the aggregate. Surface should be dry.
Component A and B should be mixed by low speed mixture for 3-4 minutes till homogenous mixture is obtained. Mixture is poured, spread evenly by means of a serrated trowel. After spreading the material evenly, turn the serrated trowel and smooth the surface in order to achieve an aesthetically higher grade of finish. Roll immediately in two directions with a spiked roller to ensure even thickness. Make sure that a continuous, pore free coat covers the substrate.
Mixed product should be applied in max. 30 minutes in about +20⁰C. Waiting time between coats should be minimum 10 hours in +20⁰C and maximum 48 hours. If waited more than 48 hours, the surface should be sanded.
Application must be protected from water, direct sun light, wind, frost and rain at least 1 day.
If necessary, after mixing part A and B, aggregate is added to the mixture as needed and stirred again until a homogeneous mixture is obtained.
19.5 kg component A + 5.5 kg component B = 25 kg set 20.
