The Wonderful High-Pressure Water Spray-gun

One of the list items under Finish the Porch, is Stain the Ugly Concrete Stairs. They are a dirty gray-brown. Andrew thought the church had put a quick slip of cement over them just before selling the house, and has intended to get rid of the steps or at least improve them since they moved in.

Today we bought special cement stain, and borrowed a high-pressure water spray-gun from a friend. This puts out water at a rate about half of the professional spray-guns (which you can rent from Home Depot), but the friend said it was perfectly adequate for cleaning moss and dirt off steps before staining them.



It works like a charm -- pull the trigger, point and spray. And the dirt disappears as if you were spray-painting Clean all over it.

We are left now with a clean step and front walk. And the discovery that it wasn't a cement slip, after all, but paint that the church slapped on before selling the house. So we aren't sure the stain is going to work -- but it is not returnable, so we'll try it before anything else. One option is to rent a professional spray-gun and shoot the paint off -- even the spray-gun we have, given time to work its magic, will push off the paint. Whatever we do, we have to do it soon -- the walk and steps look horrible -- pallid gray with patches where the paint has pulled off. The dirty steps were at least a rather warm and homogeneous brown.

Another use for the spray-gun is the pathway bricks. It turns out that the sprayer melts the mortar off the bricks like butter. So I spent a very fun hour this afternoon shooting off mortar, cleaning 80% of the bricks in the time it would have taken me to scrape 5% of them (and more thoroughly than by hand).

Now I want to rent a high-pressure sprayer but I'm not sure what to use it on. Maybe the shingle siding.

Have you seen the wonderful epoxy concrete paint/coatings? They come in lots of colors and have a colored undercoat, then you sprinkle a multi-colored spatter effect on them, then overcoat the whole thing with a clear sealer. They look really great. I see dieplays for this paint at every Home Depot I go into, plus there are ads on hgtv.

If the concrete stain doesn't work, you could try this stuff in a color to go with the new porch floor.
