The exterior plaster is lime, flyash, sand and chopped straw. The texture is smooth and there's no vapor barrier. The problem is it's quite porous. Rain soaks in without even thinking about it and there's a wet ring for the bottom 6 inches (15 cm) of the interior of the bale wall.<br> <br> We've used this plaster in less frightening conditions with great results, but this is a place where everything is tested: it's always moist, the winds are amazing, everything rusts immediately.<br> <br> It appears we need more of a sealer than we have, so what will allow vapor to escape? Water glass? Xypex? Thompson's Water Seal?<br> <pre class="moz-signature" cols="72">--
