Epoxy paint V Epoxy paint?

[mickshep]

What I would like to know is, What is the difference between a very expensive epoxy marine paint and a less expensive epoxy floor paint, I assume they are pretty much the same animal or are there different grades of epoxy or is it a case of adding the £££££'s along with the word 'marine'? I expect to be starting the job quite soon and I wondered if anyone out there had tried alternative 'Epoxies'. Cheers all, Mike.

i think you will need to quote specific makes to get a better answer, but if you get it wrong it will be a hell of a mess to sort it out, you'll wish you'd spend the extra money, good marine epoxy lasts for ages - 10 yrs +

I'd bet they were much the same thing, only marine epoxy is stamped marine!

G'day Mick,

Take great care, there is epoxy and epoxy, you will have to take a very close look at the can labels, the spec sheet and MSDS sheets to see how close the two products are; I doubt they are even close.

Epoxy resins have come a long way in the last 5 years, I'm even using a water based (Yes water based) epoxy resin at the moment to protect standard resins being degraded by chemical attack.

Avagoodweekend......

Agree with Oldsaltoz, there are more epoxies than there are days in the year. choose the wonrg one at your peril

Epoxy base .... are basic and similar ... but the composition will be different in its other additions .... using one for other job will be foolish.

Think on various types ...... reasonably flexible even when fully cured epoxy .... stiff will crack epoxy for non flexing static jobs ... etc.
Compare West Epoxy with other Epoxy glues ...

I think you are now starting to get the picture ... there are vastly different styles and make up of epoxy products ....

Now onto painting .... beware of some epoxy paints that dull and chalk as part of the protection they are designed to give some applications ... others will give years of gloss finish - the cans similar. Marine paint is IMHO an extension of better quality paints and you can save money by going to a reasonable Paint store and selecting carefully - instead of just picking of Chandlers shelf ...

Funny enough with the move of our laboratory - we are looking at the resin coat for the lab floor to comply with accreditation reqt's. The resin is semi flexi to allow for floor movement etc. and acid / oil resistant ... but it is not suitable for any other purpose ... as it's poured on ... then spread in a thick layer about a mm .... (probably a lot more than the stuff you are quoting ...)

Pretty much as I thought, horses for courses and all that, I'm looking at a Jotun marine product at £39 per 5 ltr plus vat, designed for brush application it's prob' the one I'll go for. Mike.

Excellent example, I had such a floor laid in our lab for the same reasons. Quite good for its purpose, but was granular and semi-soft, so boat applications are a bit limited.
