I'm not sure if this is the correct forum for this question. If there's a better one, please tell me.

My house in Florida is 3 years old. When it was built, I added a large lanai (roofed & screened-in area) across the back of the house. The lanai has a painted, knock-down concrete floor. Outside the lanai is a full-length concrete pad that looks like a sidewalk. After I moved in, I had a birdcage (fully screened addition) added off the lanai. The birdcage has a (badly) poured concrete floor.

So now I have this large, outside living area with 3 different concrete floors. I want to have some type of "flooring" to make it all look much better.

The problem is that my husband grows orchids out on the birdcage. When he waters the orchids, whatever he uses for fertilizer drains out the plants & stains the concrete. Because the birdcage has a large low area, the water/fertilizer collects and becomes nasty in the Florida sun & heat. Washing with a power washer has resulted in badly pitted concrete.

My question is this: what type of outdoor flooring do you all recommend?

I'm considering:

1. Thin pavers (the type used a for driveways, walkways, and pool area), but I'm not sure if they'd tolerate the fertilizer, or stand up to the power washer.

2. Outdoor tile, but I wonder if the 3 types of concrete finishes, plus the high& low spots might be a real problem.

3. Poured concrete that is colored, textured, and stamped with a design. Again, like the pavers, I'm not sure the surface would hold up to power washing.

Thanks in advance for your help & suggestions,

Ellen
