As you pick the waterproofer for your tent, you should also consider the tent fabrics. Tents come in multiple fabrics, and it is important to choose a spray that will work well with your tent. Let’s look at the different tent fabrics available.

  • Silpoly

A man-made fabric that is less stretchy under loads and when it is wet. Nevertheless, this fabric tends to be expensive, and only some specific silpoly weaves are best suited for tents.

  • Silnylon

These fabrics are also man-made, and these are the same material used for making plastic bags. Silnylon is nylon fabric, which has been blended with silicone.

Silpoly and silnylone are both good tent bodies, but the difference lies in the amount of silicone impregnated in the fabric.

  • Dyneema Composite

Another type of tent fabric is Dyneema Composite, which is also known as Cuben Fiber. This is a rare fabric that’s also more waterproof than silnylon and silpoly. It is an ultralight fabric that also happens to be very expensive.

  • Duck Cloth Tents

If you are using the old military surplus gear, you should know that the sprays will not make your tent water-repellent.
