Just ordered my Epoxy! Need Advise.

[benzu]

So I was talking to John (Sale Rep.) at Raka and he was telling me that I should epoxy both sides of my wood. Do I need to do this or can I get away with just doing the exterior portion of the wood? Hope that makes sense.

Thanks,

Mike

...wood that is not sealed on both sides has a greater tendency to warp...this may not matter in all cases but sure would for a door or wall........

Mike,
I only plan on using epoxy on the exterior side, but the wood will be sealed on the back side with different things... glue, contact cement and water based poly. The exterior trim will be fully sealed and anchored with epoxy though...

Mmmmmph, water base poly that sounds like a better idea and easier.


thanks Dean

Benzu, we used water based poly on the interior as well...keep in mind that water based poly is generally not UV protected and takes a couple of coats + to totally seal....

Thank for the info, yes I'd only use it for interior parts.

speaking of Raka and epoxy, which kit would be large enough to cover a Puffin/Lil Guy?

[benzu]

I told them my square footage (200 sq ft.) and they told me that the 3 gallon kit was big enough.


Mike

[madjack]

I would recommend their 3gal kit as well...it will be plenty for your needs and since unmixed epoxy had a VERY long shelf life, any that remains can be used later for other projects...I would also order some filler such as their phenolic micro ballons.........

So my wife and I were about done sealing the other side of our exterior walls with waterbase poly when I researched glueing and using poly this is what I found...

Just for kicks, I emailed both the makers of Titebond and Minwax. These were the replies:

Thank you for your inquiry. I do not recommend sealing your wood before
bonding with Titebond III. Like all of our traditional wood glues,
Titebond III is designed to bond bare wood to bare wood. Applying any
type of sealer before bonding will prohibit the glue from penetrating
into the pores. A strong bond can not be achieved if our wood glue can
not flow into the wood's pores when pressure is applied. For sealed or
finished wood, you may want to consider using a polyurethane glue or
epoxy. I hope this information is helpful to you.

This sucks, now I just took about an hour sanding off the poly. Next comes epoxy, hope that goes better then this.

Mike, you could usr a urethane based adhesive over the poly...we seal everything and do 90% of the finish work while it is still sitting on the work bench...when we do our assembly, we use Gorilla Glue(urethane) or a urethane based constuction adhesive such as PL brand available at most box stores or SikaFlex(urethane) available at marine or Austinhardware.com....Titebond or other water based adhesives will not work over poly......

this is my situation,i am ready to attach my aluminum to my teardrop sides which are bare wood right now,what type of glue do i use?

Is contact cement good for a outdoor application,my 20 plus years as a carpenter says NO!!

Some people don't use any at all. I used Henry's 663 outdoor carpet adhesive.

[madjack]

Mikey, I wouldn't use contact cement onna bet...the best any of us have found is the outdoor carpet adhesive that Rocky mentioned(or a similar type product)...personally, we don't glue our AL down...we allow it to float, captured by the edge and door trim along with the fenders and lights...we do seal all the ply first and use a urethane based adhesive/sealant on all the trim......
