Reface blown bricks

Question

I'm going to reface the blown bricks on the wall round the garden of my house should I pva the surface of the brick first and would you put some pva in the mix itself if so how much, thanks

The best option is to find a suitable match and replace the brick entirely as once a brick as spelched it has lost its strength to fight the elements and you will be forever repairing as it will never be completely frost free which is what causes the most brick to spelch water ingress then the frost expansion blows the face off the brick hence the spelching effect .

Hi mate, in answer to your question. Yes you need to PVA the areas first, mix the PVA so that it looks like milk but not thick. Don't put any in the mix. Paint the walls with the PVA, let it dry then paint them again, when area is sticky apply the cement. You can put plastersizer in the cement if you wish. GOOD LUCK.

Philip · Answer

Use PVA 50/50 and brush onto the brick surface, give at least two coats before you use cement and yes a little in your mix won't hurt the job. If you can match the pattern of the brick by using a stroke brush and then maybe a tint dye to get the colour right.

If the brick has blown best thing to do is remove and replace it.
