pva surface of brick before refacing?
I'm going to reface my blown bricks on the wall round my garden, should I pva the surface of the brick first?

Depends on type of btick
You could do but the best way to rectify a spelched brick is to replace the whole brick as the brick as failed and any future water ingress will just force the face to spelch again with the frost also look at the pointing to spelched area
Yes my advice would be to pva the wall first it gives a better bond for any rendering or refacing
You can buy brick waterproof sealant from most builders merchants
Yes bonding
Yes, also get as much sand and cement in all the blows as you can. blue grit is also better than PVA.
PVA (polyvinyl acetate.) is plastic based and only seals, grit-based primers do so much more plus hold the refacing in assuming a render much better.
I hope this helps

Yes
Pva over the bricks helps in different ways such as coating the surface area of the brick protecting the surface from the water and weathering, and also it provides a better surface to work on if re facing or rendering or other aspects. So i highly recommend using Pva on a lot of things a very good reliable invention.
