Protection And Materials Used

The first, and probably most important, factor youll be concerned with is how well the spray will waterproof your boat cover. Simply put, sprays that use chemicals tend to be more effective for waterproofing purposes. Ingredients such as Teflon, silicone, and petroleum distillates form a more effective moisture repellant.

However, you need to balance this against the obvious downsides of using these harsh chemicals. They are unsafe to breathe, and may be flammable as well. Additionally, they might affect the look and feel of the fabric in different ways.

How To Create Waterproof Seams

When youre making a boat cover, outdoor storage cover or tarp, you want to be sure that it will keep your possessions safe, clean and dry. But did you know that when you sew, the holes the needle creates in the fabric can leave your cover susceptible to leaks? If youre concerned with leaking seams, never fear. We’re going to share a few ways you can seal up your seams to keep them as watertight as possible.

Testing Anti-Wick Threads water resistance

If youre sewing a new project, you can add built-in protection from leaks by using an anti-wick thread. Antiwick thread is a bonded Dabond polyester thread with a wax coating that was specifically designed to prevent weeping seams. The way Antiwick works is that the wax plugs the stitch holes to prevent water from leaking through. Its the same V-92 polyester thread that most marine fabricators use, just with an extra coating so its still UV, mildew and abrasion resistant. You can see for yourself just how well Antiwick Thread works by watching our test video.

How To Waterproof A Boat Cover: The List Of Materials To Have

To successfully waterproofing a sun awning for sailboat or motor boat, you need to be well equipped. Thus the material identified as a priority is:

A canvas brush

The average duration of a boat cover waterproofing operation is 2 hours. This duration is a little longer when you operate by application with a wide brush.

Should You Cover Your Boat When It Rains

Well, boats are meant to be used in the waters . Does it really hurt your boat when it is uncovered in the rain?

Boats should be covered during rain because it not only damages the boats interior but can also flood the boat with rainwater if the bilge pump is incapable of pumping out water or if the drains are plugged with trash or any. And boats without covers are vulnerable to insects, sun, rain, snow, etc.

So, it is essential to cover the boat with a waterproof cover when it rains. Even the water-resistant fabrics do not inherently repel water but, rather, are treated not to let the water soak through. If it is a normal boat cover , its better than no cover at all.

Waterproof boat covers will protect the boat during rains by repelling the water completely. Yet, the rainwater will not sink the boat, but in heavy rains, there is a possibility. Later it will be a mess if you didnt cover the vessel or used a cover that isnt waterproof.

However, occasionally leaving the boat uncovered in the rain for an hour or two is OK, but ensure the bilge pump is working well enough and the scuppers are clean without any debris or trash blocking them. But the cover is essential if the boat is kept in the waters.

And it is a good practice for every boater to remove the boat from the water when it rains and properly waterproof the boat, which will protect the boat from rains and other damages.

How To Waterproof Canvas

Canvas Covers

Traditional cotton canvas is waterproof in the same manner that traditional wooden boats are waterproof. The cotton fibers like the wooden planks swell when they get wet. This seals the weave.

But because cotton canvas loves mildew and hates bird droppings, it is not used aboard pleasure boats much anymore. It has been replaced in most applications with either a vinyl-coated polyester or woven acrylic.

The vinyl-coated fabric is waterproof for the life of the fabric, but unlike traditional canvas, it doesn’t breathe. Unless it is well ventilated, condensation wets the underside of the fabric, eventually leading to mildew. Vinyl-coated fabrics are a good choice for Bimini tops, but unsuitable for enclosures such as sail covers or boat covers.

Acrylic canvas, like cotton canvas, is a tight-weave fabric. It is waterproof yet breathes it stands up to ultraviolet radiation better than any other fabric it snubs mildew it resists staining it is colorfast and comes in every color imaginable and it looks marvelous. Not surprisingly, acrylic canvas Sunbrella being the best known is the most popular marine fabric by a wide margin.

How Do You Prevent Covers From Collecting Water

Standing water can dramatically impact the durability of even the burliest of boat covers. A tight fit is essential so that the water runs off the flat surface rather than pooling on top. Tom recommends considering a semi-custom or custom cover. Semi-custom covers are designed to fit several makes and models with the same hull type. Most boat covers come in sizes by range , which means that the perfect boat cover to fit your boat may have some excess fabric.

To prevent pooling be sure to tie or strap things down so that the covers lie taut, and also consider a support pole or support system, which sits inside the boat, under the cover, to create a tent-like sloped surface to avoid pooling water. A custom cover made just for the year, make and model of your boat, and designed to cover its individual accessories, will fit like a custom-tailored suit, says Tom. It costs the most but is the easiest to put on and remove, is the best for trailering, and will last the longest.

Before taking any action, its important to thoroughly clean your boat cover. To do that, grab a soft brush and scrub the canvas/nylon. If there are any stains that you cannot remove with a simple brush, you can also hose down the cover and even use some mild detergent.

Ventilation Could Be A Problem If The Boat Is Covered For Long Periods

These waterproof covers wont allow any air or water to pass through them. Condensation inside the boat could be a problem, resulting in causing mold or mildew due to the trapped moisture under the boat cover.

To prevent mold and mildew inside the boat, you need to select a boat cover with vents capable of releasing any air that may build up inside the vessel over time. If vents are not an option, you need to look for other cover materials .

Keep everything dry before covering the boat for extended periods. If water is present in the hull, it will evaporate over time. If the cover has vents, it is OK because the water vapors will escape through the vents. Otherwise, it will cause mold and mildew.

After taking the boat out of the water, just leave it for some time and remove all the water inside the hull and the bilge area . Then wait for an hour or two and then start covering the boat. Now mold and mildew occurrences are less even if you use waterproof boat covers.
