Garage/workshop to render

Good evening all,
My first post.
My old garage/workshop (labour of love) which has been slowly renovated over the last few years, but hasn’t been touched for the last year, requires rendering over a mixture of old Cheshire bricks and external blocks and as you can appreciate the blocks are soaking wet and bleeding through.
My question is - can I SBR the blocks now to seal them until spring/summertime, then re-apply/tacky over the surface just before rendering?
Your advice is much appreciated.
Cheers
