Smart Tips for Using Waterproof Tarps This Season

A good waterproof tarpaulin solves more problems than most people realize. Whether you need to protect furniture, cover equipment, or create temporary shelter, understanding how to use these versatile sheets properly makes all the difference.

Picking The Right Tarp For Your Needs

Not all waterproof tarps handle the same tasks equally well. Thickness matters when you're planning long-term coverage versus a quick weekend solution. Heavier tarps with reinforced edges stand up to wind better but cost more and weigh more to move around. Lighter options work fine for short-term jobs or areas with minimal wind exposure.

Clear tarps let light through while keeping rain out, perfect for greenhouse-style protection or covering plants that still need sunlight. Standard opaque tarps block both water and UV rays, which makes them better for equipment storage or creating actual shade. Think about what you're protecting before you buy.

The grommet spacing around the edges affects how securely you can fasten things down. Grommets every 18 inches give you plenty of attachment points for windy conditions. Cheaper tarps sometimes space them 3 feet apart, which works okay in calm weather but struggles when storms roll through.

Securing Your Tarp Properly

Wind turns unsecured tarps into dangerous flying objects. The key is creating enough tension to prevent flapping without pulling so hard that you rip the grommets. Start by anchoring opposite corners first, then work your way around the perimeter. This distributes tension evenly.

Bungee cords seem convenient but they can snap back painfully if they slip free. Rope or ratchet straps give you better control. Here's a reliable securing method:

• Attach one corner firmly to a stable anchor point

• Move to the diagonal opposite corner and secure with moderate tension

• Work your way around the remaining edges, adjusting tension as needed

• Check that water can drain rather than pooling in the center

• Add extra tie-downs anywhere the tarp spans more than 6 feet unsupported

For ground coverage, use sandbags or weights on the edges instead of stakes when possible. Stakes work but they create puncture points that can turn into tears over time. When you do use stakes, place a reinforcement patch between the grommet and stake for extra durability.

Creating Effective Drainage

Flat tarps collect rainwater in the middle, creating a heavy pool that stresses the material and can cause collapse. Slope is your friend when setting up any overhead coverage. Even a slight angle lets water run off instead of accumulating.

You can create drainage by making one side higher than the other, or by placing a support pole slightly off-center to create a peak. For hangar tarpaulins or large covers, a ridgeline down the middle with slopes to both sides works best. The water runs to the edges and drips away from whatever you're protecting.

Watch where the runoff goes. Directing a stream of water straight onto plants or toward a building foundation causes new problems. Position the low points so water flows to appropriate drainage areas.

Maintenance That Extends Tarp Life

Clean tarps last longer than dirty ones. Dirt and debris act like sandpaper when wind moves the tarp around. Every few weeks, hose down your tarp while it's still in place if possible. For deeper cleaning, take it down and scrub with mild soap and a soft brush.

Check the grommets regularly for signs of tearing or rust. Small tears near grommets can be reinforced with repair patches before they spread. Metal grommets that show rust should get a coat of waterproof sealant to prevent the corrosion from spreading into the tarp material.

Store tarps properly during off-seasons:

• Clean thoroughly and let dry completely

• Fold loosely rather than cramming into a tight bundle

• Keep in a cool, dry place away from direct sunlight

• Avoid storing in damp basements or hot attics

• Check periodically for mold or mildew growth

Creative Uses Beyond Basic Coverage

Think of waterproof tarps as temporary walls or roofs you can position anywhere. During outdoor gatherings, angle a tarp to create a windbreak without blocking the view. For camping, a tarp hung properly provides rain shelter that breathes better than a completely enclosed tent fly.

Ground sheets under tents or outdoor furniture prevent moisture from wicking up from below. This simple step keeps things much drier than just relying on the bottom layer of whatever you're trying to protect. Cut the tarp smaller than your tent footprint so rain doesn't run under from the edges.

In gardens, tarps make excellent temporary walkways during muddy seasons. They also work for catching leaves during cleanup or creating a clean workspace for potting plants. The waterproof surface rinses clean easily when you're done.

Dealing With Common Tarp Problems

Flapping noise drives people crazy, especially at night. Reduce flapping by adding more tie-down points along the edges, particularly in the middle of long spans. Small bungees attached every couple feet create tension that dampens movement without needing major anchor points.

If you're using tarps in freezing weather, ice buildup can add significant weight. Knock ice off periodically, or better yet, increase the slope so ice slides off naturally. Never let thick ice accumulate because the weight can tear even heavy-duty tarps.

Sizing and Measuring Tips

Order tarps bigger than you think you need. A tarp that barely covers leaves no room for securing the edges properly. Add at least 2 feet to your measurements in each direction for adequate overlap and anchoring space. For vehicles or equipment, measure the tallest and widest points, then add extra.

Custom-sized tarps eliminate the frustration of trying to make standard sizes work for odd-shaped items. When you have exact measurements for a specific application, custom options often make more sense than buying several smaller tarps and trying to overlap them.

Pay attention to the actual finished size versus the stated size. Some manufacturers measure before hemming and grommets, so the usable area ends up a few inches smaller than advertised. Check the specifications carefully before ordering.

The right waterproof tarp, properly used and maintained, handles countless outdoor challenges. Spend a bit of time on correct setup and regular checks, and these simple sheets will protect your stuff through whatever weather comes your way.
