Our new super-strength effects coating lives up to the Valspar name by providing excellent durability and hardness to important projects. In fact, WeatherXL provides excellent colour retention and the best protection for fading and chalking.

Bigger, bolder silicone modified polyester (SMP) coatings are cutting-edge formulations each feature a two-coat finish recognized for its durability, offering even stronger protection and endurance during extreme conditions than its predecessor.Created to withstand most anything that comes it's way, our specially formulated WeatherXL silicone-modified polyester coating is designed to go where it will be abused - maintaining extreme resistance to abrasion, chipping, and marring with tremendous colour and gloss retention.


  • Best resistance yet to chalking, fading and scratching for SMP

  • Exceptional colour and gloss retention

  • Outstanding colour consistency

  • Superior weatherability
