How to Reproof a Waterproof Jacket

If you have a favourite waterproof jacket and you find that rainwater is not beading on the surface like it used to, but is saturating the material instead, it might be high time to reproof it. First of all, you should wash your jacket as it may simply be dirty (you can see our washing guide here), but if it still fails to repel moisture, it’s a definite truth that you need to resort to reproofing.

Wash-In Method


Once your jacket has been cleaned, you should clean out your washing machine’s detergent tray. This is a similar step for washing, but you’ll want to clear out any remnants of your washing product.

Get yourself some wash-in waterproof, we have some in our cleaning and proofing range.  Follow the instructions for volume and temperature settings before setting the washer.


Let the cycle run with the waterproof, and once completed, allow the cycle to repeat and dry out the jacket. Waterproofing liquids activate with heat so if your product allows you to tumble dry or wash at 40°C, the heat will help activate the coating.

Once finished, you can hang the jacket to dry out or if you use a tumble dryer, you will be good to go. Test run the new coating when you get the chance and if the process worked correctly, you’ll find water once again beads on the surface.

How do you spray a waterproof jacket?

    1.Take your Spray-On Waterproof
    2.Hang your waterproof jacket on a washing line to allow for even spraying
    3.Spray the product evenly on the outside of the jacket from about 5-7 inches away
    4.Double check the jacket has been evenly covered at all areas to ensure no section has been missed
    5.Wipe off any excess spray with a damp cloth – emphasis on damp!
    6.Then sit back and allow the jacket to dry naturally
