Frequently Asked Questions
Are canvas tarps better than poly tarps for sun protection?
Yes — a tightly woven, heavier canvas (like 18 oz) blocks UV rays more effectively and resists fading longer than thin poly tarps. Canvas also holds up better to abrasion and repeated use, though it is heavier and pricier.
Will a waxed canvas tarp trap moisture and cause mildew?
Canvas breathes more than plastic, and the waxed finish sheds water while allowing slight airflow. To avoid mildew, remove and air-dry the tarp periodically or ensure the covered furniture is dry before covering for extended periods.
How should I secure a tarp against wind?
Use the stainless-steel grommets and polypropylene loops to evenly tension the tarp around the object. Space tie-down points about every 2–3 feet, add corner reinforcement if needed, and avoid leaving loose flapping sections that catch wind.
