What is the difference between water resistant and waterproof tarp material?
This is a very common question that is worth exploring to ensure you are actually purchasing what you need.
Water resistant tarps can withstand the entry of water into the fabric for a short period of time while waterproof tarps offer complete protection from water or moisture. Waterproof products can be taken under water (submerged) and will maintain impermeability, but resistant products cannot.
Water Resistant – Canvas Tarps
Canvas tarps are water resistant. They are treated with oil & wax to make them water & mildew resistant. Thus, if canvas tarpaulins are pitched or angled properly the water will run or slide off the cover. However, if water pools or collects, eventually the tarp will begin to perspire, absorb moisture or seep. Water resistant canvas tarpaulins protect and conceal equipment or machinery while eliminating condensation. Canvas tarps are breathable and very strong. However, canvas tarps are not recommended as car or boat covers, as wax and dye in canvas tarps may rub off and stain car or boat exteriors. Canvas tarps are not recommended for use as over-the-road trailer tarps or truck covers as they are more susceptible to rips & tears than Vinyl tarps. Canvas tarps are not suggested for indoor use as space dividers, sidewalls, tops or roofs for tents, canopies or building structures as they more susceptible to rips and tears than vinyl.
Recommended uses for canvas tarps:
- campgrounds
- light trucking
- equipment supplies
- agriculture
- curtains
- painting
- shades
- firewood/lumber
Waterproof – Vinyl Tarps
Not only are vinyl tarps waterproof, but they also have high tear and abrasion resistance & offer UV protection. Since Vinyl tarps are waterproof, they completely block water; however they are not breathable. In addition, they are also oil, acid, dirt, grease and mildew resistant, and easy to clean by simply wiping the material. Vinyl laminated polyester is also flame retardant, which is ideal for school gymnasiums, theaters, warehouses and businesses.
Recommended uses for vinyl tarps:
- boat or car covers
- high strength trucking
- roofing
- field covers
- construction & industrial
