Default Failing mortar

I am looking at painting a brick exterior and will be using PPG Timeless. Some of the mortar in between the brick is "loose", meaning that when I run my finger over it that a sandy layer will rub off. It is not coming out in chunks or clumps just a fine sand. Does anyone know of a product that will "tighten" this layer up and make it suitable and solid enough to apply paint. It is not so bad that it needs tuck pointed yet.

Maybe SW Loxon masonry conditioner. I've had good look with it

I always use Zinnser multi-surface waterproof sealer. It is good for masonary and wood surfaces,and is paintable. I have found my exterior paint lasts longer on weathered surfaces if I apply this product before my primer and paint.

There was a post on PT some time back where someone used an interior grout sealer...there was even a vid if I remember right. Good luck using the search function! The product might work for this...
