Tongue & Grooved fixing instructions

Tongue and groove boarding can be installed horizontally or vertically. In horizontal application, start at the bottom and work up with the grove edges facing downwards to assure a weather-tight wall. Siding up to 6” (152mm) wide can be blind nailed with one board nail per bearing toe-nailed through the base of each tongue. Wider boarding should be face nailed using two nails per bearing. Ring shank nails must penetrate 1_” (32mm) into solid wood (see figure below).

In vertical application, start at one corner with grooved edge toward the adjacent wall. Use a level or plumbline to ensure that the first board is installed vertically. The grooved edge of the first board may have to be trimmed to ensure a flush fit. Siding is nailed to horizontal blocking lines installed between studs or to furring strips (see Wall Construction). As with horizontal installation, pieces up to 6” (152mm) can be blind nailed and wider pieces should be face nailed.

Does cladding require treatment?

It depends what species of timber you are using, for instance cedar and larch are specifically used for cladding because they are so naturally durable they do not need to be preservative treated. Most hardwoods do not need treatment either, if you were to use softwood redwood & whitewood then you would need to have the timber preservative treated, with a double vaccum treatment, either clear or green/brown treated.
