removing cement based adhesive from wbp floor

[rysiu1]

Hi, am new here.

Renovating bathroom to shower room, walls and ceiling all good, but after placing a new wbp floor and starting to tile with ceramic floor, made a big mistake. Have removed tiles, but have lumps of the flex cement based adhesive, which is now dry.
Any tips of removing this? Many thanks for any help, as I am chipping away and there must be a quicker way!

a big sharp wood chisel or a similar tool is best, it needs to be kept sharp tho. be careful with it. you should be able to scrape it off
