Porch addition
I'm planning to add on to my existing raised concrete porch to have it run the length of the house. My plan is to eventually cover the entire porch with brick.. that being said, I plan to use plywood as the floor for the addition and then cover it in brick. Is there some sort of sealer I need to put on the plywood prior to putting on the brick? Weather isn't really an issue since I live in Southern California. Any help would be appreciated. Thanks

Plywood won't be a good substrate for brick. Since the original was concrete, is there a possibility that you could extend the concrete with another pour and have it all the same?

Thanks Chandler.. I think you're right. I don't have a great deal of experience with concrete. The porch is raised about 4ft and would span about 8ft, so obviously the concrete will need to be reinforced in some manner (steel perhaps.. I don't think rebar would do it).. any ideas. Thanks

Since you will be, in essence marrying two concrete slabs together, a good way to accomplish this is to drill 11/16" holes in the mating edge of the old slab about 6 to 8" deep and epoxy 5/8" rebar into the holes to where they stick out about 2 or 3" shy of the end of the proposed slab. Form up the outer edges of the new pour, and make the pour. The rebar in the old and new pours will tend to keep them stable. You see this quite often in highway building, where a pour is stopped and started again (of course on a much larger scale).
