Remove construction adhesive

Bbrown3381 | Posted in General Questions on

Concrete block house exterior redo. The old system went……do you believe this……block, 1×4 spacers, 1″ foil faced ridgid foam, t 1-11. Well, the t 1-11 rotted big time. Got it striped down to the
CMU walls. Plan to. Use the removed treated 1×4 as spacers over ridged foam on the new system. Problem is, the spacers all gave a squiggle of adhesive on one side. So, do you think I can place the bad side against the ridged foam face and just “seat” the protrusions into the foam and achieve a straight face…or do you. Think I need to remove the adhesive. If removal is necessary any ideas on how to do a bulk removal. Could run it thru my sander, or ,planer or on edge thru the table saw. Not real keen on these methods but tried scrapping with a sharp edge and the time factor was pretty high.

    You can dull your power tools with this task if you want, and eat up a few hours. But most builders would buy new 1x4s, because 1x4s are fairly cheap.

    Thanks....that was my first choice...just seeing if I can do done recycling.

    If you are dead-set on recycling the boards, I'd use your plane. Change the blades out for an old or cheap set first though. The adhesive will ruin them.

    Personally I'd try to remove it with a sonic saw and scraper blade first.
