‘Waterproof’ fabric, when properly tested, can withstand a specific amount of water pressure (measured in mm) before allowing water to penetrate. ‘Water resistant’ fabrics offer less protection and will typically have a lower hydrostatic head rating – they'll repel light rain but aren’t designed for prolonged exposure or heavy downpours.

Water-resistant fabrics rely on surface tension to deflect water, while truly waterproof fabrics create a barrier. Water-resistant materials will likely require more frequent reapplication of sealant and aren't suitable for heavy rain or prolonged exposure; waterproof options are built to withstand greater levels of moisture.

Generally, genuinely waterproof fabrics – particularly those with high hydrostatic head ratings like PVC and some treated canvas – will be more expensive than water-resistant options. Lower cost materials may require more frequent replacement due to wear and tear when exposed to the elements.

Ensure the cover is made of a material with a hydrostatic head rating of at least 3000mm, preferably higher. Check seams and zips are reinforced – these are often points of failure – and consider UV resistance to prevent premature degradation from sunlight.

Yes, but choose wisely! Waxed cotton or treated polyester offers the best combination of water resistance and warmth for dog coats. PVC is less breathable and might overheat your pet, so ensure the coat allows for adequate ventilation.

The hydrostatic head rating indicates how much water pressure a fabric can withstand before leaking through. A higher number (e.g., 10,000mm) means greater waterproof resistance and better protection in heavy rain; always prioritise fabrics with a high rating for outdoor use.

Yes, you can often apply waterproofing treatments to enhance the performance of water-resistant fabrics. However, these treatments need regular reapplication – typically every 6-12 months – to maintain their effectiveness and ensure continued protection against the elements.

UV radiation can degrade many waterproof materials over time, reducing their water resistance. Look for fabrics that are specifically treated with UV inhibitors to extend their lifespan and maintain their protective qualities when exposed to prolonged sunlight – particularly important for outdoor furniture covers.

Often shoppers overlook the hydrostatic head rating, opting instead for cheaper ‘water resistant’ options that quickly fail. Similarly, neglecting seam reinforcement and UV resistance can significantly shorten the lifespan of a waterproof product; always check these details carefully.

Follow manufacturer’s instructions – typically spot cleaning with mild detergent and avoiding harsh chemicals. Regularly inspect seams and zips for damage and repair them promptly to prevent water ingress. Proper storage when not in use is also crucial.
