Zamberlan HydroBloc Waterproof Conditioner Spray

I have had a set of Zamberlan boots I bought over 25 years ago. Used Hydrbloc waterproofing cream occasionally, but boots had become inflexible, less comfortable and leaked. Used this spray all over the boots and the results were amazing. Boots regained their flexibility and comfort. Followed up with waterproofing cream and they survived a wet Exmoor walk in comfort and without a leak. Wish I had ordered the spray as well as the cream before. Not cheap but less than new boots!

This works as described on my Zamberlan nubuck leather boots. It absorbs within about 5 minutes so applying the recommended two coats doesn't take long. The hydrobloc spray does not alter the the leather surface of the nubuck, which is good. In comparison to the most popular alternative nubuck waterproof treatment, NikWax Nubuck & Suede spray, Hydrobloc works just as well though it isn't the same stuff. The two products smells slightly different, which gives me the impression that the product formulas are not quite the same. Both products are a milky solution of similar consistency. NikWax has a smell similar to PVA wood glue, whereas Hydrobloc smells a little like an organic solvent odour I associate with new leather, even though it is clearly water-based and non-toxic. Neither smell unpleasant and the little that ended up on my hands hasn't caused any reactions. I deliberately bought my latest boots without a Gortex lining so the only water proofing comes from the factory hydrobloc treatment and the additional treatment I am applying. I don't expect the boots be as waterproof as wellingtons but I do expect them to withstand day long damp conditions. I will be applying the hydrobloc little and often. I will update this review if I find my boots don't live up to expectations. As it stands Hydrobloc gets 5 stars.

This item arrived promptly and in good condition. It works well.

Great product Seems to work better on certain places better than others. I maybe need to try reapplying it.

Boots not leaking but they shouldn’t be yet. This seems to refresh them and I assume it’s good.

Easy to apply and did a good job of water-proofing a pair of lightweight fabric/suede walking boots (not Zamberlan). Not sure it wass really necessary, but I applied it 3 times over a period of a few weeks, and still have 50% of the content remaining.

Old have bought the cream cheaper

At first sight, this seems like quite an expensive product. However, you've just spent at least a couple of hundred pounds (and maybe a lot more) on a pair of excellent Zamberlan boots (and they are excellent). So are you going to get a low-cost generic waterproofing spray, or a slightly more expensive one from the same manufacturer? Given that they know exactly what materials they make your boots from, and what will best protect them, I think the answer is obvious.
