2011年4月4日 · Hi everyone, I did some research and found these paints that are qualified as moisture / vapour barriers: (The table shows the grams of VOC per litre, Brand, Model #, and coverage.) under 50g/l -- Kelly-Moore -- 95-500TDS - 250-300sqft-gal - <1 perm 73 g/l -- Miller Paint -- Vapor-Lok Moisture Vapor Barrier Primer #1545 325-375 sqft-gal - <1 perm 74 g/l -- …

2021年7月14日 · The problem is just about everything that is sold for basements is for waterproofing, and paint can be waterproof and have high vapor transmission -- like exterior latex paint for example. There are tons of basement waterproofing paints on the market but the Ames one is the first I've found that has a perm rating available.

2024年10月21日 · Latex paint isn't a vapor barrier unless you specifically used vapor barrier paint. I pulled up the SDS for the paint you mentioned and the associated primer (not sure what you used exactly), and it doesn't mention anything specific about vapor permeance, which makes me think it will behave similarly to any other latex paint around 5 perm-ish ...

2020年4月8日 · Installing a true vapor barrier on the underside of an open cell foam insulated unvented roof deck creates a moisture trap.

I intended to use MemBrain under my drywall, but the open cell installer claims the paint works just as good for half the cost. What are thoughts on this? The stack up is a 2x6 wall with 2x2 …

2010年8月17日 · At the dawn of our current interest in building science, sheets of polyethylene were routinely stapled to interior framing before drywall was installed. The idea was to block the flow of water vapor into exterior walls. (Some builders tried to make their polyethylene seams airtight, so that the poly would do double duty — acting as an air barrier as well as a vapor …

2013年11月27日 · Back in the 1930s, a rash of paint-peeling showed up across North America. One thing that most of these homes had in common was insulation in the walls. Painters put two and two together and decided that the problem was the insulation. According to building scientist Bill Rose, the painters surmised that the problem was happening because insulation “draws …
