What Else You May Need
You may need Nikwax Tech Wash before applying this waterproofing treatment. The product is also a refill, so a compatible TX.Direct 300ml or 500ml spray-on bottle is the relevant container to have on hand.
Before You Decide
Confirm that you want a 1000ml refill, not a ready-to-use standalone bottle. Check that your bottle is a TX.Direct 300ml or 500ml spray-on bottle, and make sure you can complete the Tech Wash cleaning step before treatment.
