Frequently Asked Questions
Can grill or generator covers be used to protect cushions and rugs?
Yes — many grill and generator covers are made from heavy, waterproof materials and can be repurposed to protect bundled cushions and rugs. Choose a cover with sealed seams, sufficient size and secure fastening so wind won’t shift the cover. Keep in mind covers designed with ventilation or access (like the Porch Shield top opening) can be useful if you need combustion/airflow for equipment but aren’t necessary for just covering textiles.
How should I measure my cushions and rugs to get the right fit?
Measure length, width and height of the largest single item or the stacked bundle you’ll cover. Add a few inches on each dimension for easy draping, then check product dimensions and look for adjustable hems, buckles or straps to tighten the fit. If in doubt, pick a slightly larger size with cinch cords to avoid strain on seams.
How do I prevent mildew under a waterproof cover?
Allow items to dry completely before covering. Choose covers with vents or breathable panels to reduce trapped condensation, and check covered items periodically on prolonged wet stretches. If possible, store cushions upside down or slightly elevated on pallets to keep airflow under the cover.
