Hi chaps.
I have just put my Catnic CG 90/100 x 3.3Mtr lintel over my window opening and want to carry on building up with brick outer and block inner.
(its only a single storey extension so only need 3 rows of bricks amd 1 of block).....question is ....do i lay the first row of brick/block directly on the metal lintel or should i lay them on a mortar bed on the lintel.
Thanks
