About this deal
The glues in most plywoods don't stand up to water over time and will begin to degrade, leading to delamination of the plywood layers. How often would you suggest retreating - I am quite careful and make sure that all water is wiped off as much as possible.
What’s more, the drip tray underneath can be removed and rotated 90° so that you can orientate the angled drainer to suit your kitchen sink. I would in general dissuade you from trying to make something like this from common plywoods which have glue joints of questionable durability. This ceramic angled drainer is designed to sit directly on any work surface, though is particularly well-suited for protecting a wooden worktop. Expansion across the way has been surprisingly non existent (mitred corners are still nice and tight). This drainer unit is angled, and comes with a surface design that channels all the water towards the drainage spout.
The Arena™ self-draining dish rack from Joseph Joseph is an excellent choice, with an innovative concentric design that holds cups and dishes securely. Am I Ok to to leave it at that or should I put matt varnish over the top (would prefer not too as it looks icky.
The drainage grooves become deeper towards the edge of the work surface, allowing water to flow directly into the sink. Without a built-in draining board, it is sensible to ensure that kitchenware can be left to dry beside your sink without leaving standing water that could compromise your wood work surface.Worst case, if it cupps (hopefully on the bottom, I will plane it down, and give it to someone in the family and start again. New sink is coming into new kitchen next week - living the dream with a double butler sink and no draining board. Yes but I don't know what it is for and I don't use it except for piling more stuff on as in current kitchen there isn't enough worktop. Traditional thinking would deem that the laminated wood strips would be your best defense against twisting and cupping. With the length of the shank there was some chatter but very shallow final passes came good in the end.
