Is Wonderboard used with brick for an outdoor bbq top?
I apologize if I am posting in the wrong forum - don't know where to post about barbecues.
We are doing this reno concurrently with a kitchen reno.
We have a built-in brick bbq in our backyard which currently has a tile surface( top) and is made of 'regular' bricks. Since the tile has caved in ( built 20 plus years ago) and the bbq is old, we are replacing the bbq with a new ss one and putting in a stainless steel door beneath.
We wish to replace the tile with 'used' bricks ( I guess some call them antique bricks - the ones that have some white in them) and also rebuild the old pass-through beneath the kitchen window using the same used bricks.( in order to 'match' the antique bricks that are in our kitchen cooktop area, directly opposite the window pass-through.
The old pass-through has already been demolished except for the 3 ( iron?) bars beneath that are attached to the stucco wall and were used for supporting the old tile surface. These bars will stay in place and be used to lay the new pass-through surface.
The bricklayer/bbq guy says he will use Wonderboard beneath the bricks, for both. I know nothing about this except for what I've read through online searches and the conclusions seem to be ambiguous.
Is Wonderboard commonly used for this purpose and what thickness should it be? If not, what is the best material beneath a brick surface?
Finally, the quoted cost for both projects is $895( labor and materials, excluding the ss door which we will install and of course, excluding the ss bbq which we have already bought) with work to be completed the same day. Is this an expected/reasonable price ? We live in Southern California.
This contractor seems to be the best choice among the 3 we interviewed ( one guy quoted 1500).Should we sign on the dotted line? We are just so tired of getting estimates but we also have gone over budget for the kitchen, so we want to make sure we are not over-paying.
Thanks a lot for any help!!
