Curlpak is described as a 100 percent biodegradable product that is manufactured on a specially patented machine that shaves paper-thin, fluffy curls of wood from scrap wooden blocks that would otherwise be taken to a landfill.
By passing the scrap block beneath the board again, determine the thicknesses of wedges needed for truing the additional horizontal furring strips.
Then position the scrap block directly on the flat surface of the replacement board and hammer down firmly on it to seat the replacement level with the surrounding floor.
Set the board into place tongue-side first, then press the board flat by tapping against a scrap block placed on the board.
Protect undamaged shingles with a scrap block.
Use a scrap block to protect undamaged shingles.
Fit a scrap section of floorboard over the projecting tongue of the replacement board, then tap with a hammer or mallet against this scrap block to seat the replacement firmly against the existing board.
To move the section up into position, hold a scrap block against its lower edge and strike the block with a hammer.
If you need to move the section upward, hammer against a scrap block placed beneath the section's lower edge.
