Fill the gaps with foam than cover with something that can take everyday wear and tear. Yes you can paint foam, but it is not very resistant to impact as is.

When I remove the strips on the walls there is a gap of about 1/4". Can I use the foam insulation to fill that gap and then paint it. I am going to be repainting a bedroom in a mobile home.

With proper installation the electrical boxes will end up surrounded but not filled with foam. The liquid foaming material is injected through a small hole into the wall cavity between studs and expands as it reacts. The insertion hole is then repaired over. Be sure to check with your home owners' association, local building codes, and reputation of any contractors you use.

Is it possible to spray the foam in the walls? Will the foam spread into the electrical boxes installed on the exterior walls? Can this be sprayed into an area the will surround the dryer vent?

The rigid foam board is still an effective insulation if it is adequate thickness and well installed with no gaps for convection losses. However, sprayed-in expanding foam insulation is better at creating desired thickness as well as sealing all the gaps between joists and plumbing lines. Since it is waterproof and closed cell you should have no problems with rising damp. Be sure to check out several contractors for expertise and price, and compliance with local codes. I'm sorry I don't have any suggestions for Connecticut installers. Hi Duane 2 :) ,

The result is a very cold floor in the colder months. If I have foam insulation installed it would completely fill the gap. Should I be concerned with wicking action between the concrete and the insulation? Can you identify any installers in Connecticut?

Firstly, I would address the ant problem. If they are large ants such as Carpenter ants, I would treat the area to eliminate them. They may be traveling to wood material in the joists and flooring. Also check for moisture, which ants seek out. Smaller ant species might be nesting in the foundation. Big box stores have several products that can eliminate critter infestations. Regarding the concrete stoop; is it stable and secure? Patching cracks can be futile if the concrete is moving around with foot traffic. I have used expanding foam to fill and bridge large gaps around a slab foundation. The yellow foam does not stand up well to sunlight so it is prudent to overlay it with caulking and paint. After filling with the expanding foam, cut away excess and sand if necessary to have an even or slightly lower surface. I have have good success with gray concrete caulk, which covers the foam underneath, is flexible, waterproof, and matches the concrete color. Hi John,

I have large ants that are traveling into the gaps behind the stoop and would like to seal the gaps. Is there any paintable expanding foam or better yet gray color expanding foam? I have used the yellow stuff before but am hoping there is different colors or paintable formulas. thanks So I have a front concrete stoop with gaps between the foundation and stoop.

The existing batts, if thick enough, might be adequate, depending on your temperature differential between ground and living space. However, using expanding foam to seal gaps and cracks around the perimeter would be a good plan. Anywhere that you can prevent drafts from disturbing the insulated space adds to efficiency. Sealing gaps with foam and caulking will definitely help keep out critters. Hi Duane,

There is about 8" between the concrete and the bottom over the floor joist's. The joists have batted insulation between them already. This void is enclosed on 3 sides and a covered deck on the 4th. So there is no chance of rain or snow getting in. Can i use a spray foam to fill the entire void to keep critters out & to help insulate? We have an addition that was built over a concrete patio.
