Drip Lock Spray 400ml Nylon

Concentrated reproofing compound

Tent fabric should not be blistering or peeling before you attempted to rescue it.

This is quite common when Tents have been stored for long periods, and very prevalent if the Tent was stored not fully dry, or in a damp environment or also if stored in a high-temperature location. Probably 90%  of “Nylon” tents today are made of Polyester of varying grades from different Countries and Textile Mills, generally coated on the inside with Polyurethane for water resistance and oftentimes the outside with a polymer for UV resistance. Some superior models also have a Flame-retardant coating. These coatings also give the base-fabric additional strength. With water-ingress from damp conditions or layer-melt from high heat during storage, the coatings will either lift away from the base Polyester or the layers will bond together and tear when the Tent is opened.

If the fabric is then washed or brushed to remove the flaky bits, the coatings are destroyed and the fibres of the Polyester also damaged.

No Waterproofing liquid Sealer is going to give the perished fabric a new life. In some cases, on small (about 3cm²) brushed areas, the Sealer will bind the fibres back together quite effectively and the Tent will last another year or two, but larger patches will likely still allow water through, even after many brushed-on coats of Sealer. The “foundation” to build on, is just too fragile.

I want to assure that we have been selling DripLock very successfully for over 10 years. If the product “does not work” we certainly would not even be offering it. Our reputation is too valuable to us to risk.

Incidentally, the formulation used in Drip-Lock is identical to other Brands such as NuSeal, CampGard, NuProof, Rainblock  and several others on the market and produced by one factory.

Coverage per m² depends on the fabric of your Rally Tent, eg. Cotton Canvas will soak up a lot more Sealer than a Polyester material since Polyester is already Waterproof- treated at Factory level.

The brush-on method usually covers about 7m²/lit for Polyester and approx. 4m²/lit for Canvas, but can be even less on older “dried-out” Canvas.

You can apply the product undiluted with a Spray-gun or dilute with 10% Turpentine for larger coverage.

Note that it is usually sufficient to simply brush over the seams, since that is where leaks originate. However, if the main body of the fabric is allowing water through, then sealing the entire surface by the Spray-method is recommended. Too much brushed-on liquid can cause a thick “skin”,  prone to cracks and, obviously, will add weight to the Awning.
