I'm about to put up a set of 5 heavy solid oak shelves. They weight about 7kg each with things like books to be sitting on them. I've decided to mount to the sides of the brick + plaster alcove they're going in rather than the back, which is a dot and dab wall.
I'll be using using 6mm x 50mm Fischer UX plugs, which on my tests, fix really well into brick. The shelves will be sitting on/screwed into 1 inch thick, 1 inch tall, home made wooden side brackets which run the same depth as the shelves (260mm). 2 screws in each bracket into wall.
I'll be wanting them equally spaced vertically up the wall and I was wondering what my tactics should be if I hit mortar?
• Is mortar useless to attach to? Can I can get away with it?
• Increase the diameter of the wall plug?
• Increase the diameter of the hole and insert some wooden pieces?
• Drill another hole a couple cm's left or right of the mortar and hope I'm not on a horizontal part of the mortar? (Add a 3rd hole/screw)
• Move shelf by 1.5cm vertically and make peace with the irregularly spaced shelves?
I have 10 holes to drill, so chances are I'll hit some of the crumbly stuff at some point. The house is 1930s so it's pretty old mortar too.
All comments and advice welcomed! Cheers,
