Well, looks like this thread has now become a shop front. Every other post seems to be someone blatantly selling their products. This is supposed to be a discussion forum and I believe that the only times people have given company names in the earlier stages of this discussion is when someone has been asking for them. Even peoples names now are adverts in themselves.

If you look closely Preloved have a section for advertising.

So, please can any future additions to this thread be kept to discussing and only a tiny bit of advertising. Thanks.

Sorry Gary - seem to have hit a nerve. Many of our customers initailly did not know new cast iron baths are available - so don't even think of looking for them in the usual way (Yellow pages, Preloved ads etc). We found that we must direct market our baths. This way we can raise awareness - the more we sell, the more we can buy and the cheaper we sell to you - good business sense.

Fair enough £300 sounds pretty cheap. But if I have filler, acid etch and primer left over from my car then if it's the same stuff all I'll need is the white topcoat and a refurbishable bath. I'd think £100 tops to get both and beleive me on the budget we have a £200 saving is seriously useful. But like I say I'm not sure if it's the right stuff. Gary, TubbyUK, supersurfacer, anyone, are you willing to divulge the materials needed or is that all trade secrets?

I can divulge that you will NOT be able to buy the coating necessary .
From anywhere.
I think someone suggested that we use "marine coatings " or something .
If only it were that easy , I would save a fortune on import costs ,
and shipping from the states .
People have used all sorts of "paint " on their baths , i can guarantee that it will not last more than 12 - 18 months in the best cases .
I have been thinking the same as you Gary , there are guidelines about advertising in this FORUM .
If you want to advertise on preloved ....there is a facility for it .
Unfortunately you have to ...PAY FOR IT !!!

You are able to buy the professional resurfacing products from a company called The Lab in London - they used to supply me but I now buy from the states - cheaper and better products.
One of the 'safest' (I use the term loosely) products they sell is called ISOFREE. It is used alongside a catalyst and a reducer. You also need a bonding liquid to ensure correct adhesion. They work out of a specialist bathroom retailer called THE WATER MONOPOLY, London. - look up the numbers on Yell - I don't have the number to hand - ask for Simon.
You will need spray (and respiratory) equipment and spraying experience is a definite advantage - but a good, long lasting finish is possible.
I think the minimum they sell is 1ltr of each product - ask to buy a sample amount of each, that will be enough to do a bath or two.
I have not intentionally plugged this business, just advising - not advertising ;-)

Hello Phil,
I thought I might just stay out of this cat fight but alas it is not possible. May I suggest to all involved that these good fellows submit a sample of their "special material that all comes from US of A" to a neutral party, to apply to test plates using each ones suggested application process. Then we submit them to an independent testing laboratory. We each pay our share of the costs and lets sort out once and for all who's who when it comes to material performance. In the mean time I suggest you pre-empt the test results and use a Tubby Kit.
Cheers

Great Idea , but flawed sadly . The tests cannot factor in the application of such coatings by :

A : An idiot

B : A person that doesn't care how long its going to last.

My experience is that these are the single most important factors.

I recently did a job where the previous coating had to be removed. Not that there was much of it left on the bath anyway ,
It had been done by an employee of a large franchise , using , one can assume , their "tried and tested coating " which I'm sure was an excellent coating . The weak link was the moron applying it had not prepared the surface at all . It was as shiny as the day it was made .

Hi all, Cheers very much for all the tips, surface solutions cheers for the supplier link.

I just realized that when I talked about polyurethane paint being the choice for cars but plastic lining your lungs I was actually talking about two-pack paint. Oops sorry for mixing my terms. Has anyone ever tried this stuff? It dries to a glass smooth surface without polishing. In fact once it dries it is actually too tough to polish and even sanding is not easy! One serious problem though is that it's very nasty and I imagine that health and safety would not let you use it mobile in people's homes, maybe that's why you lot don't go near it. However, if anyone has the bath equivalent to a spray shop I'd be interested to know if you've tried this stuff.

Anyway I'm getting off topic. TubbyUK, you recomended I go for one of your kits rather than get the professional stuff. I'm not trying to antagonise but I will have the spray equipment, the acid etch and the primer from my car work. All I need is the topcoat, which I think will actually be cheaper than your kit.
Also I imagine your pros don't use the kit and there is no doubt a reason for that. However, I would be very interested to find out what they do use and if you sell it.
I think it's a case of horses for courses and in general DIY stuff is not as good as the stuff the pros use (or it's more expensive), otherwise the pros would use the DIY stuff. I for example would not consider respraying my car with aerosol cans from halfords because an infinitely better finish can be acheived using proper kit.
Again im not slating the kit as I've never used it and I'm sure your kit fills a market niche and most imprtantly is suitable for an untrained person who is clearly not going to buy a spraygun or deal with hydroflouric acid etch. But for someone who has the equipment and knowhow there will nodoubt be better options.

Phil

Oh by the way I think the idea of submitting test samples is a good one, although I have no idea what these things cost. It might be a good selling point for you all to be able to say my resurfacing service (or my diy kit, applied as recomended on this instruction sheet) will survive on average 'blank' hours in 'blank' conditions. In fact if you decide to do this then if i have got my car spray booth sorted by then I might be able to supply you with a two-pack sample to compare, just for curiosity's sake.

Hello Phil,
My point in this whole useless debate is, that the Tubby material is as good as the products generally bought from paint manufacturers and supplied to the "Professional bath resurfacing"
firms. The term "Professional" being bandied around only applies to a person making money out of it. From our research carried out over many years I am not aware of any other bath resurfacing organisation who develop and manufacture their own products specifically for the purpose. Not material made for cars or boats or anything else and used for baths. We have tried your idea of car/boat/whatever over the years, they dont take the hammering that a bath coating has to. At the end of the day, you get what you pay for. Have a Professional job done, get a guarantee etc. etc. and pay your money great! Choose to do it yourself if you are on a budget and can't afford the service great! But for goodness sake will everyone stop inferring that Tubby is somehow not equal to the coatings used by the "Professionals" Put up or shut up.
Cheers

Oh Dear, Oh Dear, Oh Dear. Back to this touchy subject again.
I think I read somewhere that they did do tests in the states to determine the longevity of the coatings they use over there.
The only thing to come out of it was that the coatings they used were all very similar BUT the main thing that affected the life of the coatings was the preparation and the bonding agent used.
They concluded that if a bath isnt cleaned properly and coating is applied it will not last anywhere near as long as a coating applied to a thoroughly cleaned and prepped surface. This test was carried out with bonding agents and not acid etching. The bonding agent used also had an effect on the outcome but not as much as the preparation.
As for testing out Tubby and coatings that are applied through other means, I may just purchase a kit myself and do a half and half re-surface of a bath to see what the finish looks like against the coatings I use. If I was to do this Tubby how long would I need to leave your kit before I could put masking tape on it to enable me to spray the other half of the bath??
Obviously this little test will only be for myself to see what the finishes are like.
I know this isnt quite what you had in mind Tubby but is that putting up enough for you.
Cheers, Gary.

Oh okay then fair enough, so what is the difference between the stuff in the kit and the stuff your guys would use if I called you in to do it for me or is it the same stuff? Presumably they acid etch or use bonding agent rather than sanding? And I can totally understand why hydroflouric acid cannot be just stuck on the shop shelves and sold to anyone. I work at a university and hydroflouric acid is used in some of the labs because it is the ONLY acid that can dissolve some mineral and meteorite samples that we work with. It really is nasty stuff and if you get it on your skin it will eat through your bones! But I guess the stuff we use is more concentrated than you guys - horses for courses again. But I guess you've all been trained to use and neutralize this stuff. Actually, TubbyUK it would be good if you could offer a comparison between what your guys do and what is done using the kit. Again I'm not trying to provoke, just discus as I'm actually quite interested and you're probably the person that knows the most about the kits.

I only mentioned two-pack car paint because it is significantly tougher than the polyurethane enamel car paints as well as givng a high gloss finishing without polishing. I thought maybe the reason you don't use it is that it would not be possible to spray with it in situ. But then again I obviously don't know how bath polyurethane enamel differs from car polyurethane enamel. Again I'm not necessarilly suggesting that two-pack is better than what you use, just that it's an interesting comparison and wondered if anyone has looked into it.

I assume that's what we're all following this thread for and why it's so huge - because we're all interested.

Cheers again for the info TubbyUK and Andy.

Hello Gary,
You are most welcome to do that. I can even supply you with a spraying solvent and you can spray some and roll some to see the difference. The masking tape can be put on after 24hrs.
Send me your address over our website and I will organise it.
Cheers

Hello Phil,
There are a number of ways to prepare the surface.1. Mechanical (sanding) and degreasing.2. Acid etching/sanding and 3. Adhesion promoters, these are usually presented in a Propyl Alcohol base.
The last two methods are not suitable for diy use because they require training. Their only advantage against method ! is that they are very fast and efficient. Method 1 is time consuming but if carried out correctly achieves identical results.
The development of Tubby came out of our Professional material to satisfy the DIY market. This gives the diy advocate a better chance of achieving good results with a highly proven material.
Cheers

To all who may be interested..
Follow this link to a company who are dedicated to PRODUCING as well as supplying high quality resurfacing products.
They are a very genuine and will gladly offer professional advice (and I mean professional) on safety of and correct application of resurfacing materials.
There are so called 'professionals' out there - but most are importers / suppliers. These guys produce and provide direct from the lab.

http://www.hawklabs.com/index.html

No doubt someone will dish this company - but rarely will you find a more informative supplier

I think you'll find that their Flagship primer system , Ultragrip , is an epoxy primer and contains isocyanates .
Which are known to be carcinogenic.
Also as they are in Illinois , it rules out D.I.Y ers as the import costs , if they would send a small quantity , would be prohibitive.

Hi folks,
Just viewed the last few posts and would like to highlight a few misconceptions:

1. Epoxy does not contain isocyanates. Polyurethanes and acrylics usually do, and they ones that don't are usually pretty useless, so you have to use a bonding agent to get the stuff to stick.

Unfortunately epoxy yellows and chalks with the passing years.

2. To anyone considering playing about with these preparation chemicals on a diy basis, the best advice is don't!! - there are simply too many risks..
eg HF (as I think Phil pointed out) will eat your bones ( I worked as an electronics manufacturing engineer in semiconductor industry , and I've seen what it can do, and it aint pretty....).
Not only will it eat your bones (and give you cancer from breathing it...but the damn stuff looks like water and doesn't burn until hours after its got on your skin and burrowed beneath , so treatment can be bolting the stable after the horse etc.


Spraying anything containing isocyanates without an airfed mask is asking for respiratory problems

Spraying anything containing solvents without an organic filter is asking for cancer - Xylene and Trichloroethane are commonly used in these processes and are highly carcinogenic.

Having researched the risks I restrict my work to a few days per week..even using respirators etc this is essentially an unpleasant job! I now teach maths part time and do baths part time, so I reckon I can justify the slogan 'maths and baths'...in fact I'm shamelessly plugging the maths rather than baths bit cos....I offer an online maths tutoring service up to A level if any of you folks have kids who could do with some extra help coming up to exams..:-)

Curious .! I have spoken personally to the technical dept of the
previously mentioned producer who confirmed that their epoxy coating does contain isocyanates .
Perhaps he's wrong ?

Yes Andy, I'm afraid he is...neither of the two epoxy chemistries (amine or amide) require isocyanates to activate.
Perhaps he was thinking about acrylic or polyurethane?
If I am wrong about this then I'll be very worried, cos I tend to favour epoxy for its superior adhesion qualities, but I wouldnt touch anything with iso's with the proverbial barge pole.!
I know a few guys marketing ' specially developed bath coating produced after extensive testing over several years in their laboratories....' ..yeah right! - you go round to their 'lab' and you find a guy decanting a 5 gallon drum of car paint into half litre cans in the garage at his house!! Take all this nonsense about coatings specifically develped for baths with the pinch of salt it deserves.
There are three common processes - epoxy, urethane, and acrylic, and they have all been developed as general two packs by the Duponts and ICI's of this world, and are marketed under a several different brand names.
These companies are constantly striving to reduce VOC's and harmful chemicals. Unfortunately the solvent-free stuff just isnt as good in terms of finish and adhesion at this point...but there is light at the end of the tunnel. I know of one chemical company which is evaluating a two pack which is based on an entirely new 'safer' chemistry . No doubt it will have some drawbacks too, but hopefully it will be a reasonable compromise in terms of safety and performance. I'll keep you guys posted..and NO..I'm not trying to sell anything!
Cheers
