Engine Room clean and insulate

[B][/B]
Hi All
Next project is under way and I need some guidance.
1) I have cleaned out the insulation from the engine bay and now need to remove some chunks of glue from timber and fibreglass; if any one could advise as to what is an effective product to do this, my appreciated.
2) Once done what prep work should I do to the timber/ glass prior to glueing on the next lot of insulation/ sound sheets?
3) Where around Sydney can I get the insulation sheets at a reasonable price? I know Whitworths have the BUT I would have to sell the boat and my grandmother to pay for it which is kinda counter productive as granny has not done anything wrong :-)

Any guidance would be appreciated.

Regards
Manni

Remember fire proofing as well.

Re: Engine Room clean and insulate

On the old glue use 3M Adhesive Remover or naptha.

- You might want to check what the rules are "down under" in this regard before you buy anything, including the glue.

Here, the USCG is pretty specific on what can and can't be used when carrying passengers. I do know they take a very dim view on certain foam insulation due to fire hazard on any boat, and wouldn't be at all surprised if your local agency feels the same way.

You also have to worry about your insurance company balking at a claim if you used the wrong insulation and glue.

Re: Engine Room clean and insulate

Careful of fumes when cleaning up old glue...ensure good venting using fans. Consider retaining the insulation without glue. Temperature variations in the engine space are too much for most glue. I am doing the same job and plan to use painted, expanded aluminum sheets and screws into the beams on the overhead to retain the insulation. Much easier to R&R and clean when needed. Looks nice as well.

Re: Engine Room clean and insulate

Hi All

thank you for the feed back, it is much appreciated. Good idea "Idorakeeper".
If the rain goes away today I will head out and see if this is feasible. Much better option then adding more chemicals to the glass.

Re: Engine Room clean and insulate

I've found that laquer thinner will remove some things that just about nothing else will. It is flammable and toxic though. Sometimes sanding it the only way to get some things off. I also have a nice wood chisel type plane. The blade is out front of the body and it will trim off stuff without nicking the base. Very useful in corners. My favorite wood tool that I use for all kinds of things. I got it for Christmas one year.

Like this one: https://www.lie-nielsen.com/product/...lane?node=4063

Chisels can work but you have to be very, very careful to keep them at a low angle of attack, and sharp. Curved surfaces take lots of small passes but it will be easier to get off what is left if you get the bulk of it off. Some glues will never come off if you have to penetrate a thickness with solvent.

I am not sure what you can get in Australia but I intend to put in some of the high tech sound insulation material that has been discussed on the forum before. It isn't cheap, and the products I have found are dark, but they are lighter with longer life and more effective then the foil-covered fiberglass material often used. They have similar panels at autoparts stores here, for under engine hoods and at the firewalls. Used by hotrodders rebuilding cars.

Re: Engine Room clean and insulate

Try CRC Gasket remover, removes most glue. You spray on and let work for 15-20 minutes then remove with a plastic spatula or similar firm gadget. Have used it on gaffs tape glue and it works a treat.
Good luck with your work

Happy lead free sailing from Lucky

Re: Engine Room clean and insulate

I couldn't find anything in the forum but found this online. I need to do the same thing as my insulation is past it's prime.

As is true with virtually all of these products, there will be no 3rd party testing results for either sound attenuation (STC), or insulating value (R or K value).

More importantly, the flammability of these products for both flame spread and smoke development is rarely stated.

These two characteristics are measured under the ASTM E84 protocols, as determined by NFPA.

For any material used on board, my requirement is to utilize products (that have been measured by a UL listed lab) that do not exceed a 25/50 rating.

For higher temperature/high risk applications, such as engine compartments, my opinion would be to use the most fire-resistant materials available. This would start with utilizing only materials that have performance data clearly stated. This also allows you to compare the performance of competing products.

There are a lot of snake oil products out there (the bubble insulations come readily to mind) making unsubstantiated claims. In lieu of anecdotal claims or advertising BS, look for tested hard data. Your life may depend on it.

Manni,

This product is for thermal insulation only.

The Soundown insulation is for both thermal and acoustical. But you must be sure to cover any exposed foam (edges) with flashing tape, as it breaks down and begins to crumble in a surprisingly short time.

Hi SSgtPitt

thank you for the link. It looks the same as the base insulation/ proofing product that they sell here in Sydney only it is $89 Aus per sheet, I think they must put a 3000% mark up and call it a Living in the Middle of the Pacific tax.
