Paints and coatings applied to a hydrate 80 treated surface demonstrate extended long-term performance. Its electrochemical function stabilises existing corrosion by converting the iron oxides into a protective metal complex. It also combines with surface moisture and oxygen depriving the corrosion process of the conditions it requires. Stop rust before applying a suitable primer if required. Hydrate 80 has been used to arrest and prevent corrosion in diverse applications - from massive marine installations to classic and historic automotive restoration hydrate 80 provides dependable long-term protection and rust prevention. How To Use Step 1 Remove loose, flaky rust with a wire brush and abrasive paper or power tools if preferred. As hydrate 80 will activate on clean steel, the affected area should be cleaned beyond the visibly corroded surface, this will ensure complete treatment. Step 2 Thoroughly degrease the area and wash well with clean water to remove dust and contaminates. Step 3 Shake vigorously and pour sufficient quantity into a non-metallic container. Do not return unused product to the original container, contamination transferred in this way will activate the product. Step 4 Paint over the area sparingly in two coats at 30 minutes interval using a paint brush. The first coat should be worked into pitted areas and then smoothed by brush strokes in one direction. Excess application should be avoided. The second coat should be applied at a 90-degree angle to the first. For best results leave for 24 hours after which primer and finishing coats may be applied. Powerful Protection, Superior Stable Barrier, Long Term Protection Hydrate-80 provides powerful protection to rusted steel surfaces, its electrochemical function stabilises existing corrosion by converting the iron oxides into a protective metal complex and it also combines with surface moisture and oxygen depriving the corrosion process of the conditions it requires. Hydrate-80 provides a superior stable barrier to prevent further attack. The cross-linking polymer formulated to provide the tough non-rubbery barrier tenaciously grips the metal surface forming an ideal base for further coatings, paints or anticorrosion wax. Important for long-term protection Hydrate-80 doesn’t contain chlorine which is known to transform into corrosive hydrochloric acid in rust converter applications causing under-film blistering and destruction of paint finishes or other coating products. Review: great item. - This item was as good as it said in the description and works great on rust metal was very happy with this, got another one to use when i need it . Review: Great product - Really easy to apply by brush. Once the loose rust was brushed away this stabilized the rust affected area. Brush also cleans in soapy warm water easily which I was surprised at. ## Features - Stops corrosion process, Prevents paint blisters later on, Amazing long-term performance - Neutralises forming a stable solid mass - Doesn’t contain chlorine, Surfaces do not need washing after treatment - Easy-to-use: simply brush or spray apply, Produces super-tough non-rubbery etched barrier - Safe, water-based and non-flammable ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00672US20 | | Best Sellers Rank | 5,826 in Automotive ( See Top 100 in Automotive ) 64 in Rust Converters & Rust Removers | | Brand | Bilt Hamber | | Customer Reviews | 4.7 4.7 out of 5 stars (348) | | Date First Available | 13 Nov. 2011 | | Item Weight | 680 g | | Item model number | 217 | | Manufacturer | Bilt Hamber | | Manufacturer part number | 217 | | Model | Hydrate 80 (500ml) | | Package Dimensions | 19.8 x 7.7 x 7.1 cm; 680 g | ## Images ![Hydrate 80 (500ml) - Image 1](https://m.media-amazon.com/images/I/51PKjJr-mjL.jpg) ## Questions & Answers **Q: Hi, can i ask, the main difference between hydrate 80 and detox please. thanks** A: Hydrate 80 is a paint on product that stabilises rust. Great for treating rusty body panels and larger components. Detox C is a powder that you mix with water to form a solution. You then immerse the rusted part into the solution. The rust is removed and a stable coating left. Excellent for rusty tools and small parts. **Q: Hi. Can this product be used with celulose paint? Thanks** A: I don't know. I looked into this as a rust cure for the inside of a hatchback door. I removed heavy rust with a wire brush and gel ox. I used hydrate 80 on the remaining surface, two coats. Next I applied red oxide primer (as I had an old tin) then the wax spray from bilt hamber. that was 6 months ago. all on internal panels. the received wisdom from other posters on car 'rebuilding' sites is to literally cut out any true 'corrosion' and then weld in new panels. the rust converter products treat mild surface rust well but need further paint coatings to prevent more rust. I believe but have not tried, that etch primers are used next to give a good key for cosmetic finishes. Professional finishers grind all rust away then use etch primer then etch filler as needed then paint. I would say the rust converters slow down or postpone further corrosion. Removing as much of the old rust as possible first really helps. I think coatings have moved on since cellulose paints and better technology exists unless you have to use cellulose paint. I am happy with the product for the use I had for it. **Q: Can this be used on any metal surface such as a fence** A: Absolutely. If the fence is cast iron or steel then give it a good wire brush to remove loose paint, rust etc and give it two coats of the product. The converted rust will have a hard black finish that is very stable without any further paint. It is a brilliant product! **Q: What size area will this bottle cover?** A: According to Bilt Hamber the coverage of Hydrate 80 is 8-10 square metres per litre - so the 500ml bottle should cover 4-5 square metres. You use it sparingly, and ideally you apply with a brush in two coats (painting in two directions - 1st coat one way, the second coat at 90 degrees to the first). It's quite runny so I use a small brush and work it into the rust pores spreading it around - it reacts with the rust and goes off quite quickly so you can do the second coat after about 30 minutes. Don't sand it once it's dry or you will damage the protective barrier - you can prime and paint it if you like or just leave it, it turns into a dark smooth finish. ## Customer Reviews ### ⭐⭐⭐⭐⭐ great item. *by J***N on 17 September 2025* This item was as good as it said in the description and works great on rust metal was very happy with this, got another one to use when i need it . ### ⭐⭐⭐⭐⭐ Great product *by D***P on 17 March 2026* Really easy to apply by brush.
