I had a kitchen fitted a few months ago. It was fitted too soon after replastering and moisture built up underneath and behind the base units, so the backing boards became mouldy.
Soon after, mildew eating insects called psocids (as best I can tell from my googling) have shown up to enjoy the mould.
It is a howdens kitchen, so the backing boards are thicker than the light panels you get in some units (seemed like a bonus at the time but now I wish I just had some light panels to knock out and replace!)
I think that the backing boards are integral to the structure of the units so I can't easily cut out and replace them.
There is also some bare concrete flooring under some of the units, which soaked up a load of water during the plastering.
I have a few ideas about how to tackle this but would really appreciate some advice.
I leave a dehumidifier running every night.
I am going to paint sealant over the areas of bare concrete flooring.
I am going to use a weed sprayer to spray something like Astonish Mould and Mildew up the back of the units. Unfortunately, I won't be able to see how much coverage I get. This is also an issue at the side where there is piping for the sink and gas, as the active agent in that spray can let off dangerous gases when it contacts some metals. Perhaps some sort of bleach mix would be better.
I am considering drilling some holes into the back of the units and filling the space behind them as thoroughly as I can with expanding foam. This may be a terrible idea and I'm hoping people here who actually know what they are doing might weigh in with an opinion.
Thank you
Brian
