Hello All Recently got the hallway retiled and want to put back on new skirting. Some of it had 60mm concrete screws used and other parts had glue and 50mm pins Its masonry walls but there is dry lining outside that so cant use rawl plug I would like to use glue and pins but not sure if its the best method for my setup ? I wonder why one panel had all concrete screws on it and others just had 1 or maybe none, would that because some walls are straighter than others ? I do have a good drill and long drill bit for concrete screws but how can i drill the holes in the skirting and get the top of the screw sunken into the board so i can fill it ? Thanks for any help BTW i am a person who wants to do things right and be able to remove the skirting again in the future without damage.
