Description
Finpro PU WB is a clear high-build two component polyurethane coating that provides long-term concrete protection for internal and external applications. Finpro PU WB provides concrete a durable, UV stable and hardwearing surface. This system is low VOC and fast hardening for no to little downtime.
1 x 16L Part A Resin, 1 x 4L Part B Hardener
Application Instructions
Surface Preparation
The substrate must be sound, clean and dry to ensure optimal adhesion between floor coating and substrate. Remove surface laitance, contaminants, existing coatings and curing compounds via light grit-blasting or grinding to ensure suitable surface profile (CSP 2) has been achieved.
Prior to application the surface must be free of dust and other debris. To mechanically prepared concrete, it is recommended that the surface be primed with Finpro EP WB 30.
Repair imperfections such as holes and cracks where necessary. New concrete must be cured for 28 days prior to application.
Mixing
- Using an electrical low speed (400rpm) mechanical mixer, premix Part A until homogenous.
- Add the Part B (Hardener) to Part A (Base) and mechanically mix for 2 minutes, scrape down sides of vessel so no unmixed material remains and stir for further 2 minutes.
- Leave to stand for 2-5 minutes before application for best results. Mix only the required amount that is needed based on the pot life of the product (dependant on climatic conditions). To extend pot life place mixed product in smaller buckets or trays.
- Do not apply mixed material that is unused after 2 hours.
Sealer Application
Finpro PU WB can be applied by roller, squeegee or airless spray within 1 hour of mixing.
Up to 10% water may be added to the first coat to aid ease of application. Second coat should be applied without dilution.
Roller/Squeegee
This method is compatible with Finpro PU WB, allowing application of even coats of mixed material to the prepared surface. Use a high-quality short nap roller for roller application and back-rolling.
For Smooth Finish
- Apply First Coat of Finpro PU WB at a coverage of 10 sqm per litre.
- Apply Second Coat of Finpro PU WB at a coverage of 10 sqm per litre.
