Hello, has anyone any idea what could be the problem here please.
We have put together a 7x5 playhouse , bought from a reputable company. All went well We clear Cuprinoled a week before it was built and left it to dry ( in the garage) and covered it with Cuprinol shades , 2 coats, as soon as it was up . It leaked right across the bottom half of all the laps (t&G cladding) . We filled every nailhole in all the panels, masticked around the windows, and up and down every corner joint , the butted together uprights, AND where they had attached the cladding to the frame. It leaked on the prevailing weather side. We put a third coat of Shades on , and checked over the mastic. No gaps - yet it still leaks across every lap ( about an inch above and below) for the first 2.5ft from the ground,as if they are just butted together and the water seeping in. (They arent of course, all the tongues are slotted in properly) We have bought gutters, not yet on, but I cant see them making any difference. Any ideas what is going on please? (Its a concrete base, and then sits on extra 1x1 wood underneath its own frame .)
