Restoration Foam Question

Foam Question

--------------------------------------------------------------------------------

I'm well on my way to getting my floor in.... Stringer installed, epoxied in place. and sealed in fiber glass... 1/2" plywood also incased in glass and then glued to stringer with peanut butter.. the floor was 9' long, using a 8 ft piece of plywood, left a 1 ft opening at front of floor....I had planned to tip the boat up as far as I could and our in the chemicals and let it foam filling in the open space.
I mixed up a cup of chemicals, instantly providing me more foam than I could imagine... the instructions said I needed equal parts and then stir for 25 seconds and it will take 25 minutes to react and expand to its capacity(reread and it starts reacting in 20 seconds but completes in 30 minutes).... after 25 seconds it started foaming and boiling out of my cup... I raced to my boat, dripping foam along the way and poured it into the front opening hoping it would drain to the back before expanding... not sure how far back it went but it sure foamed out the front making a ball the size of a basket ball ozzing out....

Next effort will be the cut some holes along the stringer and pour in small portions of foam and see what happens...

I can seee why boat resotrations don't replace the foam, what a pain..

Any suggestions?????????

Had a vision of putting 2 chemicals in a water bottle and shaking it up and then sticking the bottle against a hole in the floor and letting it shoot into the hull...?? but my luck the bottle would explode????????????????

Any tricks to adding foam back into the cavity????

Thank You,

Richey

Re: Restoration Foam Question

1. Read and understand the directions before you start.

2. Mix the 2 part solution inside your boat so you can pour it directly where you want as soon as it's mixed, this will give your foam solution more flow time before it expands fully.

3. Use a hole saw to drill your holes on each side of the stringer, you can save the cutouts to patch the holes with.

4. Drill all of your holes first so you can see how far the foam has traveled, this will also relieve any excess pressure that may cause your decking to bow up.

What he said.


It's not really that difficult of a job. Have a measuring cup for part A, a measuring cup for part B, and some disposable cups to mix in. Lay out some wax paper (or similar) on the deck of your boat and set the containers, cups, etc. on that in case of any spills. Pour part A into the cup marked A, pour part B into the cup marked B, pour from both cups at the same time into your mixing cup and mix like crazy with a stirring stick for 20 seconds or so. Then dump the mixture into the pre-cut hole (plan on a hole about every 2 or 3 feet). You can move to another area while you're waiting for the first batch to finish expanding.
