Take a cardboard box and place it around the area you are applying great stuff… Clean the trigger the same … This question is in the General Section. That straw can only be used once unless you stick a wire through the whole straw while it's still wet.
I use the straws … It has a barbed end, and the straw should pull right off. The plant where I worked molded polyurethane foam seat cushions. Not worth saving. I avoid using it until the job requires close to a full can.
And it is pretty great if you need exactly one can. I've used a wire hanger in similar manner. This right here. Switch to a serrated bread knife for wider overfill.
You have to do so before it dries, though. Not foolproof, but works most of the time. With my limited experience, I had good results holding the can upright so it only dispenses the propellant and giving it a quick full pressure blast.
If polyurethane … Oops. It will clear the tube. Put a small bit of acetone in a jar or container, just dip the tip in and swirl around until it partially dissolves. To join, you must be at least Responses must be helpful and on-topic. The foam doesn't stick to the straw, so it should slide out in one piece. After every use, I stick a nail in the plastic piece that the straw threads into. If you can't get all of it off, moisten your wiping cloth with acetone.

I also dip the tip of the can. When finished, barely engage the spray so only air comes out. We use one can for a job and if there's any left in the can it's essentially useless after it dries. Set the vase on the foam and add a layer of plastic wrap on top. Great stuff foam can be made to slow cure in cold temperatures by adding heat to the air around where you are sealing.
Is there anything that can dissolve the cured foam, without at the same time dissolving the door, the wheel and killing me a and a bunch of polar bears? Less mess.
