expanding foam

kostello | Posted in Photo Gallery on November 8, 2003 04:31am

I just found these pics of when I was doing our bathroom at home this morning and I thought you all might like to see.

once I got all the pipes in the masonry and fitted the valve I couldn’t figure out how I was going to get brickwork back in there.

and in a moment of inspiration it hit me.

after filling the void with foam I cut it all back and used some more foam to stick a piece of tile backer board over it all to render on top of.

    The finished shower looks great! I'm confused about the void you filled with foam. Is that stuff oozing out the outside wall? How did you fasten the backer board to the block wall?

    How many cans is that anyway? How did you shave the foam down to a smooth surface? Do you have a hot knife?

    Sorry for all the questions but the pictures are not very clear.....

      the house is a 9" masonry wall.

      the showervalve sits 4" deep so takes up half the wall.

      the va,ve has 4* 3/4" pipes going to it.

      so all the space that is filled with foam has pipes running through it.

      the foam is cut back with a regular hand saw. and the backer board was stuck on with you guessed it more foam . it had to be proped in place until the foam set to stop it from bulging out of place.

      i think it probably just 1 can of foam.

      sorry about the picture quality, they're digital photos of regular photos i came across them today whilst tidying up a bit.

        Wow! I didn't know you could use that foam for an adhesive. So how do you adhere the backerboard to the wall block? Not just that foam I hope. There must be some other way you plumb the durarock and fasten it.

        We usually build a 2x wall inside the block wall to house insulation pipes and electrical.

          Kostello:

          "the house is a 9" masonry wall."  so, what's what's that 2 wythes of brick?  BTW - I assume you are a better builder that photographer (it's the tequila talkin!!!)

          Pro Deck:

          "I didn't know you could use that foam for an adhesive."  I guess you never got that foam on ya.... let me tell ya - it don't come off with anything but time...  In that regard it's pretty similar to polyurethane constriction adhesive or gorilla glue...   If ya get on your cloths, forget about it coming off...  The directions says wear gloves and they ain't kiddin'

            Well I've got that gorilla glue on my hands and it only takes about a week of scrubbing with a brush to get that stuff off. Lacquer thinner won't even take it off.

            Come to think of it......we used that foam between a chimney and the house to fill a gap and it was pretty sticky............"Rather be a hammer than a nail"

            9" is 2 brick widths . the photos are pretty poor as they are digital photos of regular photos.

            as i don't have a scanner its all i could do.

            hope the tequila went down well.

          That Great Stuff is amazing as an adhesive.

          A friend built a fairly extensive pond, complete with upper and lower level with flowing stream, etc. using rocks harvested from his farm.

          He positioned and secured many of the rocks with Great Stuff.

          As long as it is not exposed to the sun it is suppose to hold up ok.

          However, he made the grave mistake of getting it on his hands...

          other than a peice of backerboard about 2'*2' around the shower valve there is no backer board on the exerior walls. the walls were rendered smooth with sand and cement and floated ready for the tiles.

          i had to be really careful setting everything out as the room is only 6' square.

          expanding ffoam is great. i've used it to fix door linings in places where the nearest fixing is 4" away.

          you just have to prop everthing in place and brace it really well otherwise the foam expands and pushes it all out of place.

          foam sticks to pretty much everything. plastic, wood, metal, skin. clothes etc....

          i always carry a can of foam cleaner which is an aerosol of acetone to clean any uncured foam from where it shouldn't be.
