Plywood Sales split from Mr Plywood

Sorry if everyone already knows this but i found it confusing.

I phoned Mr Ply this morning to see if they had some marine ply in stock. Then i asked where they were at underwood because the address is no longer there on their website.

They said it closed and would have to go to gold coast Labrador branch.

So ok i head down there but went past them by mistake and found "Ply Wood Sales" thinking it was them.

They said no we used to be MR Ply but we branched off and formed our own company.

Plywood sales also are at underwood too and they said Mr ply is still open at underwood too even though they say they are closing/moving?

Anyhow I bought some BS1088 stamped gaboon for $42 sqm + GST. and found there website here This Web site coming soon from their business card but its not open yet.

7 Telford place
Labrador 5529 2977

and

2/58 Parramatta Rd
Underwood 3229 3132

anyhow just some info and i found them good to deal with.

Hi Russ,

What thickness of ply was that for?

regards,

AD

sorry i forgot to mention that, it was 15mm. It was about another 60$ cheaper had i went with 12mm.

it had to buy 2 sheets to get what i needed. it's only for my 4.29 tinnie but i wanted a fairly good and strong floor to also suit a wheelchair. will give it a coat of everdure too. They also push to sell something called treated structural ply which supposed to have no rot issues at all if you put carpet on the floor or whatever.

I think everdure does the same thing and for me i wasnt buying heaps of timber so i went with the slightly more expensive stuff.

Oh and also i note the word that looks like "samling" in the Bs1088 stamp. so i guess its chinese not lloyds?

Sadly, the BS part of that stamp sometimes stands for bovine excrement :( Let us know how you go with it.

Thanks for keeping us informed, Mr Ply and Wood is one of those firms that have been regularly recommended over the years so we need to know what's happening to them. :2tsup:

Treated structural ply is plywood made from CCA treated pine.
The fungicide is pressured right through the wood.
Probably no rot problems.
Ever.
Even if left raw.

Not so sure about the Everdure. I understand it's an epoxy, not a fungicide.

Never looked at it myself, but others have written here that it is cut with solvents,
making it less effective as a moisture barrier. Especially compared with pure, 'uncut'
epoxies like BoteCote, System3 & WEST. You might want to look into that a bit
deeper before opening the tin (if it isn't already too late for that).

Everdure is a bit of epoxy and a lot of thinners.

what i am told is it seals out moisture 100% and is used in boat repair places regularly (the ones i visit anyway). And putting it along all end grain it seeps in to prevent any moisture ever penetrating the timber.

The more coats you put on the stiffer/harder the timber as well.

If someone has experienced everdure ever failing i sure would like to hear about it.

I have had it applied to 2 of my boats, one a 38' power cat & the other a 33' timber hartley. the cat it was applied all around the bow & sides where rot had been cut out and replaced with new timber and then everdure. The harltey had al the floors done and a new transom replaced and that was everdured too. this was at horizon shores marina recommended by the professionals there. The other marina was at samsons marina redland bay who also recommend it.

and for those that don't know its 2 parts 1:1 ration mix primer base & activator.

The problem with solvent is that it has to escape by evaporation, and in escaping it leaves microscopic funnels. Water molecules can then find their way into the timber or fibreglass and start the rotting process.

The manufacturers of the POR15 epoxy rust proofer also realised this, and that is why it is the only product that will halt rust, because it completely prevents oxygen from reaching the metal. Exclude oxygen and oxidation (rust) cannot take place.

In a nutshell, solvents are bad news in epoxies and products that use it for marine or anti-rust treatments are at least 30 years behind the 8 ball.

Michael Storer has also commented on this here:

Q&A Stopping Rot - High Solids Epoxies vs "Soaking" Epoxies - Michael Storer Boat Design

well all i know is i haven't heard any issues with everdure. and i personally haven't had any rot issue after using it. boat builders still use and recommend it.

I guess unless i see rot problems occur after use i would continue to use it.

keeping in mind its just patch jobs i use it on or floors. not boat building.

"Everdure"....I know some people who swear by it, I used it once as a preventative and some years later was fortunate enough to cut out some ply that I had coated with everdure, whilst there was no rot, the depth of penertration was really no better than what I have achieved with Epoxy resin, for my use I use "Boat Cote". There is a lot of discussion about the pro's and cons of thinned epoxy and while I am not an expert I did my own "backyard Tests" and for my mind it has come down to 2 things.
1, unless you kill the fungi that causes rot it will reappear (correct me if I am wrong).
2, Everdure has been around for donkeys years, well before epoxies became affordable and for me I think the new modern epoxies are more usefull in a wider range so for my mind have a greater advantage.

Kev, whats the cost of bote coat? i know everdure is expensive at $39.00 for 1ltr and you need part a and b so $80.00 each time.

is bote cote much more expensive?

oh and when i say i use it on floors i mean "false" floors(referring to boats).

Partly true. For life to exist, you need to have oxygen and water and a food source. Remove oxygen and water and you fungi will disappear. You could remove the food source, but you need your boat right to catch fish?! You could also add a toxin to kill the fungi! This is how they treat "diesel bug" which are organisms that live in the water layer within a fuel tank and which break free and clog filters etc. (water exists in fuel tanks due to condensation. Easy enough to burn it out of a petrol tank by adding ethanol to the petrol, but cannot be done with diesel)

Use a solution that contains a solvent and you're keeping a pathway open to oxygen and water and perpetuating a problem.

A bit more info here than needed, but I just wanted to make help make a point that boaties have to contend with all sorts of unwanted unwanted bugs and there are different approaches to each.:~

3L BoteCote part A plus part B kit from Duck Flat is $100.40 as at 8/11/2009
Duck Flat Wooden Boats
The stuff is made in Brissie so you might do even better there.

And thanks for reminding us this is simply a false floor in a tinny, not structurally
critical. Easy for us wooden boat nuts to get carried away with this stuff... :D
cheers
AJ

Thanks for pointing out the differences :)

Well overall for only $20.00 more its not a huge difference for a whole lot better i guess.

But i am guessing it wont go as far? given we know everdurer is thin & runny but still more coats are applied to achieve different results.

I would also like to point out too is i have somewhat been influenced by what i see in the boat yard by boat builders.

In fact i have a question here.

Recently (june) I had an insurance repair work done on my 30' timber hartley and the boat builder replaced the stern and coated it with everdure before painting.

given the impression i have here that's not something most boat builders would do?

He is a professional and been in the business maybe 25-30 years.

I am always learning myself as it is a mine field out there full of misconceptions, sales pitches, and its not something i regularly do i have to rely on what i here and see.

In any industry, lots of people do stuff because that's what they were taught to do,
"because that's what we do". Especially if there is not a significant cost or regulatory
reason to change.

25 or 30 years ago when your builder/s started out, the research data on how epoxies
actually work was not freely available, except as manufacturer claims on the tin.
International is a long-standing & trusted brand. Bote-Cote, WEST & etc were not.
Their claims would have been justifiably treated with suspicion. Having learnt
something, how many of us regularly revisit -all- areas of our knowledge to see if it is
still correct, or the best available ?

I bet none of us do.

Your builders are probably a very good builders, especially traditional styles for which
pox is not neccessarily a good thing. In this one area, they may be relying on old
wisdom, and/or being an agent for International products.

There's also the point that your Cat & Hartley both experienced rot which needed
cutting out. Were they everdured during construction?

As for what most boat-builders would do, I hope that it would depend upon the style
of the construction. As the professionals & researchers in this forum point out, it is
unwise to mix old & new methods in a hull.
