One of the down sides of our house, of which there are a few, is that it was built on a limited budget, and that meant that much of the woodwork, including the roof and supports were built with pine, which, 1) needs a lot of maintenance, and 2) it is susceptible to termites, of which we do have live action, in the cabaña, and I will have to treat it, but at the moment it is stacked with tools and I can\’t get to it, I just have to watch the sawdust gathering, once I can examine it closer, I may decide it would be better to strip the roof off the cabaña replacing it with hardwood.
However the wooden roof supports at the front of the house, have had no love over recent years and having been open to the weather were showing the neglect.
With a combination of machine and hand sanding they came up nicely, after which I gave them three coats of marine varnish, to protect them from the sun and rain.
