I work on and paint old houses and buildings on the side. I have used about 50 cans of Great Stuff foam. It really is Great Stuff ! It can be used to fill many gaps and cracks. It sets up hard and tough. Cut with a very sharp knife. Protect it from the sun with paint. Get the stuff in a red can with yellow printing. There are other brands. They set up way too soft. There is just so many ways it can be used.
When you get ready to use it have 2 pair of Nitrile gloves on. This way you get some on one hand you can peel the glove off. Wear a long sleeve shirt. Tight areas it would be a good idea to tape plastic to your arms. THIS STUFF IS VERY STICKY !
It will stick to an ice cube. Shake the can after you put the nozzle on. It is used up side down. Slowly press the lever to get it flowing. Once it starts it will speed up. Be careful with it, hard to control speed for rookies. Have a piece of newspaper to drop unwanted foam onto. Remember it's VERY sticky. Do not use it to caulk around windows ! It will expand and push the frame inward jamming the window. Fill gaps about 1/3 full. It expands that much. Protect anything you do not want it on. Very hard to remove when not set up. Stuff wadded up newspaper in holes or gaps. To keep it in from falling in or taking too much. Use it like on a bow needing repair. Put a big bunch inside let it expand out of the hole. Next day you can trim it with a sharp knife. Under cut the hole so you have space inside to hull for the fiber glass to bound to. Protect what you don't want foam on with masking tape. Tape plastic inside to back it up / hold the wet foam in place while it sets. No room to get the can in? Attach a piece of tubing to the cans tube with a clamp. Have a helper trigger it very gently. Got a loose electrical receptacle in your house. An old work box put in a plaster and latch wall? Take the cover off, shoot foam around the box through the edge between wall and box. Try to build up a wad inside the wall touching the box.Take a stick and tape it a cross the box level with the wall. Next day trim the foam away. The box should be set in the wall now. I have glue pre-hung doors in place with it. In a brick building. Still holding strong 10 years later. Want to mount something inside to hull? I would think a big bunch on a clean bilge would be a good mounting point. Maybe even glue it in place with foam. Make a puck shape area with 2-3 inch tape. carefully place tap across it top to bottom. Leave a hole to shoot foam in at top. Would that work? Stainless course sheet metal screws should hold I would think.
Have a baggie and wire tie for when your done. If you still have foam left in the can. Get the baggie ready. When you stop shooting foam put the end of the tube inside the corner of the baggie as it is still flowing foam a little bit. Seal with the wire tie with no air in the baggie. About 1 inch from tube end. This will save it for another day. Once you get the hang of using the foam you can find all kinds of places to use it.
