Hello,

I'm just wondering if using epoxy in my basement workshop is a good idea? I would like to start to put my frames together but would like to do it indoors where it's warm ( living in Canada around 40 degrees outside now and dropping).

Can you use epoxy in the cold air and would it still work properly and hold it's strength?

Thanks

Hi Fifty; Don't think the epoxy will set up in the cold, however, I see no reason not to use it inside IF nobody has an allergy to it like myself.I put my frames together with plastic resin glue ( waterproof and very strong...available fron Noah's ) but I would probably use Titebond 3 next time....easier to use...no mixing. Had to wait for a warm shop to do the batten installations as it's hard to get a good fit on the frames.

Hello Fifty - no problems.

My shop is an unfinished portion of my walk out basement directly under the master bedroom. The only time we even have a smell upstairs is when I varnish.

Be sure to looks at the technical specs of the epoxy. Most slow hardeners work best above 70 degrees F. Some say to use fast hardeners between 40 - 60 degrees F. Each is different so be sure to read the instructions for the brand you use.

The warmer the basement the faster the epoxy will set. My basement stays about 60 regardless of time of year because it is backed up against bedrock. I use slow hardener all the time and have no problems (well - except running and sagging and not staying where I put it)

Good luck and send pics

We use epoxy indoors all the time for building R/C models. Its much smaller quantity but I dont see any reason not to if no one is allergic. Just try to keep the stuff off your skin.

Great info, thanks to all. I'll be able to continue building.

Epoxy is safe to mix, apply and let cure indoors. Sanding indoors should always be done with a good dust collection system and filter mask.

I built a boat through a New England winter in my unheated garage. If you are working on the boat in spare time, it isn't an issue. Even slow hardener eventually cures in cold weather (might take 4 or 5 days). That said, it doesn't take much heat at all to move it along quicker. Often, I simply put a light bulb under the hull and turned it on. The one bulb produced enough heat to allow cure in much faster times. With the slow curing time, one really gets to know the stages of epoxy cure. If it balls up like a little eraser shavings/balls, it isn't fully cured.

I should add you need to keep your resin and hardener at normal human room temperature. You won't harm it if it is colder, but it will be difficult to work with.

Keep in mind that epoxy changes its viscosity in cooler or colder weather. SO measuring and mixing can create an issue for curing. Let me suggest a couple of things. Store your resin inside in a warmer closet in a plastic container so the gummy residue that can get down the jug or can does not get on anything of any value. People also store resins in a large cooler with a small lightbulb to keep it workable and able to blend together. Depending on if you are using pumps, thick resin does not come out correctly too. What type are you using and what method of dispensing are you using too? I also microwave my resin only in a jug with the lid closed for a couple of minutes to get it to be thin enough to blend. Its also best that your surface be warmed before applying your resins. More on that if you need some followup.

On a safety note, even if you do not have any skin allegies, its quite possible to cause harm to your liver and lungs with even uncured resins and sanding dusts while using in enclosed areas. SO use the proper respirator and keep any kids and pregnant wimmin from the areas.

This is all interesting as working with it in the near tropics here,I had to keep it on ice to get long enough working times!!!

With the slow catalyst

1) Be careful about spillage.

2) For frames, where you are gluing flat surface to flat surface, consider balcotan, or some other marine polyurethane adhesive.

I was wondering what brand of epoxy is use by most of the builders on this forum. And I see in the building with plywood book that they were using a roller to apply epoxy to the to frames for plywood installation. Is this the same epoxy as is used to glue frames together.

Unthickened epoxy the same that you use to make glue with a thickening agent such as cabosil or wood fibers is used to seal interior wood parts. Most folks will purchase epoxy resin online from the sponsor here which also helps support the forum and long term helps support the continued sucess that Gayle and the family has had since 1953.
Every so often someone will pop in with a boat that their family has built over the years and in turn will buy a set of plans to continue their own enjoyment learned and gained from the original boat built by their own father when they were kids.

A few pennies here and a few pennies there on any and all parts and pieces goes a long ways to help provide long term for some of the few family run businesses left in the United States.

Unfortunately someone at Canada Customs came up with the notion that Epoxy is a Hazardous substance (depending on the day the resin is ok, but the hardener is not, but sometimes both will get tied up) which makes getting it across the border by either mail or courier quite a chore (many won't even carry it).

Up here we are kinda left with two options. First, pay the prices for the major brands . The average price for a gallon of resin here is about 100 bucks (whether it's West, EAST, System 3 etc) plus another 40 for the hardener. OR, if we are close enough to the border (most of us are within an hour or two), hop over and buy in the U.S. (customs doesn't have too much heartburn if you show up with even 5 or 10 gallons of "2 part glue" as long as you are in your personal vehicle).

I'm relatively close to Buffalo and there is a boat building supply place that likewise sells a "house brand" of epoxy at about half the cost of retail up here, but for us you have to be picking up a little more than a gallon or two to make the trip (and the border hassles) worthwhile....

I understand, but I did not see a location and for others venturing down the pike to read this thread I added the comments. I personally think that many do not always realize that numerous other products are sold from the same suppliers of the plans.

Just an FYI: IF your kids rock band drum set cracks on either end and you decide to "poxy-grip" it back together...DO NOT heat your mixed poxy grip up in the microwave. It's just a tip, don't ask me how I figured that one out, i'm just sayin.....

Did anyone suggest heating your mixed epoxy in a microwave? Altering the viscosity of resin by heating it up is not the same.
