Exactly the info I was looking for. Thank you!I’ve generally applied my RAKA seal coat on one day, then draped the cloth and wet out the next day.
I’ve done some builds where that sequence was three days, that is, seal coat, drape, wet out, one step each day.
My nephew’s hull was built that way, it’s been 9 years and it still shows no signs of interlayer delaminating, despite harsh use.
I really like poplar, and have plans to use it for my next big freighter build for strips, but I would be reluctant to use it for gunwales, as it doesn't do well with water.
Great info Jim! Very helpful, this Is what I love about this forum!For glassing routine, Get everything on as soon as possible. You get the strongest, Clearest bond.
I learned this from a Tech at System Three.
Seal coats are fine. Just make sure there are no specs of dust on the hull, as these will raise the cloth enough to give you thin spots, when you sand the hull.
If you choose to skip the seal coat ? Be sure any cracks, or anything as small as a staple hole, is filled. They will weep epoxy away from the cloth. not good.
Me ? I take the time to fill, and skip the seal coat.
Once you are ready to apply epoxy to the cloth ? Wet it out, and wait for it to cure, just past tacky stage. This can vary, 4 hrs is usually close.
Now you can start with fill coats.
Apply Fill coats while the previous coat is still Tacky, an hour is usually long enough. The Tackiness, will prevent a lot of runs. You will thank me on this one.
Yes. I usually apply my last fill coat in the wee morning hours.
You are done. You can scrape within about 12 hrs. Don't sand for at least a week.
In a nut shell, that is my take on glassing the outside of the hull.
I’m actually in the US. Although pretty dang close to Canada, 7 miles from the border here. The poplar I purchased is tulip poplar.There probably isn't a lot of difference in this application but it's always good to remember that talking about 'poplar' can get confusing. I'm guessing that where you are in Canada 'poplar' refers to the tree of the same name that grows there locally. But in nearly the entire US the term 'poplar' refers to the Tulip Poplar tree, which is completely unrelated to trees that are actually in the poplar family.
Tulip Poplars grow fast and straight and the wood is easy to work with so it's available as a low priced hardwood (although in reality it's not very hard) in nearly every lumber yard in the US.
Thanks! Glassing today, no helper. I need to cut my bias strips for the stems, along with a layer for the football. Think I’ll lay those on for the next epoxy coat.That looks egg salad!!
Do you have help?
Be sure to knock down any dust burrs before you drape your cloth.
And have you bias cut strips at the ready for the stems…
