Basements and foundations?
What type of coatings can be used of spf when it is applied to the exterior or interior of basements? I recently used a rubberized stucco on blue board and was quite impressed with the outcome. Not sure about longevity though only time will tell. So this got me thinking if I sprayed the exterior of a basement what coatings should I use below grade? What type of decrotive coatings can I use above? What about the interior if I sprayed that directly on the block without furring what type of finish coating could I put on it. Is anyone out there doing similar? IS there a market for this? I think spray foam magizine had an article on exterior finish, but what coatings perform well and I'm not sure about below grade. I know that yield is less when spraying concrete, but is there anything else I should know?

Spray foam well except almost any paint or coating as long as it's clean and dry.I suggest a good acrylic though.Why coat below grade? The reason for coating foam is usually to protect from UV.As far as the basement go's,Check local codes in new construction they may require a thermal barrier- (drywall) |

Some building codes may require that you damp proof the "plastic insulation", or foam if used below grade. As kevinmc suggested, check with your local inspector on what is approved. Depending on the manufacture, they may have an ICC report that gives approval for 2.0 pound closed cell to be applied below grade without damp proofing. |

This guy that used to come here, named Tom Hay knows a ton about finish quality products. Maybe he's lurking? Ask him about it. |

foam on interior foundation walls MUST be covered with a thermal barrier... this is true of all plastic insulation products,,board stock,,,icf,,,puf.... even in non-code jurisdictions,,,to do otherwise would expose you to liablity in the event of some unfortunate incident (read: the insurance company will come after your a$$)...your contract for services should include "WILL BE COVERED WITH AN APPROVED THERMAL BARRIER" not "should be covered..." foam below grade only needs to be waterproofed/coated if circumstances such as a high water table exists subjecting the foam to hydrostatic pressure...at which case any waterproofing/dampproofing coating should be effective if it suitable to water exposure... |

Yes, you can spray foam on the exterior side of above grade foundations. I know of 2 foamers in Iowa that make their living by spraying above grade home foundations during the summer months. DOES ANYONE KNOW ANOTHER CONTRACTOR WHO DOES THIS? Please let me know, because to my knowledge, these two guys are the only people using SPF for this application. Thanks ahead for any leads on this subject. By the way, "Plastic Coatings" from WV has the only coating that I know of that is designed for foam that is applied to above grade, exterior foundations. It's called, "Jaxsan 600." |

they are foaming,,planeing/grinding/sanding to create a nice profile... usually applying an acrylic coating base coat followed with a low pressure air pot applied roof type granule for abrassion resistance and then topping with the final color acrylic top coat... real nice system,,works great,,lots of labor to do it right,,these guys are pro's... |

Foamdude, can you give me some contact information of a contractor that does foundations? I'd love to be able to talk to someone who's good at it. I'm trying to start my own foam business and foundations are one of the market segments I'm interested in, but there is very little information out there on this application. I had one house foundation that took me 3 weeks and my competitors showed up to the house across the street and did it in half a day. I would welcome ANY suggestions you might have.:-) |
