F R E Q U E N T LY A S K E D Q U E S T I O N S Q: Do you have installation videos? A: Yes, go to youtube.com and type in "Trex RainEscape". Q: Can I install the system myself? A: Yes, with the easy-to-follow instructions that come with the Trex RainEscape system, utility knife, staple gun and caulking gun are all you need to install the system in one or two hours on most decks. The installation goes quicker with two people.
HELPFUL TIPS TREX RAINESCAPE IS EASIER TO INSTALL WITH TWO PEOPLE Snow build-up Snow will sit on the decking and, as it melts, will run through the system. Leaves If leaves and debris accumulate in the troughs, a standard washing or a hard rain will clean out the system. If the tape will not stick In areas, such as the perimeter, brick or stucco, where the Trex RainEscape tape will not stick, use the Trex RainEscape caulking to adhere the material. Caution Do not splice trough material.
