Source for Plastic Masonry Fasteners???

[RH2]

Hi All,

I'm attaching Foam Board on Concrete Block to insulate my crawl space/basement. I planned on just using adhesive, but that's not working great. I found fasteners that look like they would be great to use with the adhesive, but I can't find a good source for them. The only place I've been able to locate them is through the manufacturer on Amazon. You can see them here:

Does anyone know of an alternative brand/source? I was hoping like a Zoro would have them and I could buy them on Friday. Over $100 for 250 seems pretty expensive.

Thanks,
Robert

Check out the vinyl shutter dept. at Home Depot or Lowes. The fastners they sell for them are very similar.

if you're going to drill, I would just drill a 1/8 or 3/16 hole , use a concrete nail and fender washers

I would recommend insulation pins and washers. You dip the pin in adhesive and press it against the concrete/block. Then you just push the insulation onto the pins, then push on the washer to hold it there. This system is used commercially to insulate concrete structures. I would think you could pick up the materials pretty cheap.

Just curious, what adhesives did you try? I used this from loctite.

If you use a urethane caulk like Sikaflex 1A it will work much better for holding while curing. I used that loctite stuff for some of my expansion joint between the slab and block on my garage pour and it didn't hold well during the cure. I had some Sika 1A and that was like contact cement because it is much thicker out of the tube.

I don't remember what I used but I had no problems gluing my foamboard to concrete and I just bought something at Lowes or HD. If you want cheaper buy some Xmas tree automotive fasteners like these
