Tounge and groove spacings

[SamG340]

Is 2p piece spacing enough for external 19mm tounge and groove ? 2p gap between each board and 2p gap where boards meets the frame

What’s the board width?

What’s the board width?

94mm including tongue

I don't leave a gap fit it snug.
Never a problem except for a few days in summer and it soon expands again.

Fit tight, it's more likely to shrink than swell unless it's very dry now .

Will do thanks for the help everyone

What wood are we talking? If it's kiln dried and been stored inside yes it will need a gap, a couple of mill is normally enough but if it's some tanalised stuff which has been stored outside it should be okay without much gap, don't make it tight though.

@Doug71 Kiln dried and pressure treated .. wasn't particularly dry when I got it but it's been dry stored for month

Tongue up: you don't want the groove filling with water!
