You could try running a bead of Perma Chink’s Energy Seal Slate Gray down eachgap from the inside.

Fiberglass would probably be fine. You should also check your local building codes for this. Blown in foam would be good also, but is about twice the price.

I would remove the trim to see what is going on behind it. You should also chink both inside and out around the top to seal it up. If there is no insulation in the roof it could be condensation buildin up behind the trim.

You should be able to use 2×4’s with the plastic vapor barrier.

Yes, chinking is for exterior and interior use. Chinking the exterior only is fine. The exterior is the right placeto start. It will hold up just fine to the cold winter.

You need to knock it all out and re-do it with either mortar for the historic look or latex chink that looks like mortar with the right color. If this is a wall that is exposed on the out side I would go with the latex.

Do not know where to get the boards. I would recommend applying a coat of Perma Chink over all of the boards to seal this house up properly.

I wouldn’t fill any more of them and you will need to be vigilant of the ones you already filled. Inspect them at least twice a year for breaks. If you cannot keep up with it you need to start digging it out.

Call Ryan at 877-788-5647 or Mike at 866-670-3020. There will be a charge.

You should use exterior primer that is tinted to the color that you would like. I would skip the sand. Perma Chink makes chink paint that has the grit in it already, but is very hard to work with.
