Hello,

Will be replacing a few wooden planks on my outside Deck.
Pretty sure they were originally from pressure treated wood, many years ago.

I'm no expert on pressure treated wood characteristics these days, but I imagine that the treatment doesn't extend more than, perhaps, 1/16-1/8 inch below the surface.
Is this correct, or...?

Got to thinking about the ends of the new planks I'll be putting down.
When I cut the plank to size, the ends will therefore be about 90% or so
of bare, untreated wood, if I am correct about the pressure treatment not extending more than about 1/8 inch.

So, what do most folks do ?
Just live with it, the mainly "untreated" ends ?
Dip the ends in some preservative ?
Or ?

Thanks,
Bob

 

Paint the ends with preservative is normal procedure if you're exposing untreated areas by cutting. Not sure you would have to do that with decking but I've never used PT decking, only bigger pieces of wood.
