*Water beading was evaluated on the accelerated exposure panels and the indoor control panels for each water repellant. All of the panels were tested for water beading by forming a 0.7 ml water droplet on the panel. The degree of beading was rated from 0 – 4 with 0 = no beading and 4 = contact angle > 90°. The degree of beading was rated initially and at 30 minute intervals for two hours.
Accelerated exposure samples were tested at an independent lab in a QUV chamber for 1000 hours. The substrate was red cedar decking. The water repellants were brush applied on all sides of 3” x 6” panels and cured indoors for seven days prior to testing. The testing protocol was an 8-hour light cycle (340 nm) followed by a 4-hour water cycle.
Percent water absorption was determined for both the accelerated exposure and unexposed indoor control panels. Each panel is accurately weighed, and then completely immersed in water for 30 minutes. After removing the panel from the tank, the excess water is blotted off with a paper towel and the panel reweighed. The difference in weight before and after water immersion is the amount of water retained in the panel and is expressed as a percentage.
Please Note: In Europe, AquaProof W/B is known as Manalox WB.
