Removing Adhesive/Self Levelling from Weyrock Floor

[simonb43]

Hi All,

How can i remove addy/self levelling from a weyrock floor. Have tried all day to scrape off using a heavy duty floor scraper to no avail. Would a chisel action drill work, or would it cause too much damage. I will be boarding over the weyrock so damage shouldn't cause me too many probs.

Thanks for all answers, Simon
