Question

We live in Chicago area and have a small screened in back porch (approx. 10 ft. x 15 ft.) which currently has a painted concrete floor. We are tired of repainting floor every couple of years (paint peels off/cracks due to high amount of moisture). Would like a new option, perhaps porcelain tile for the floor. Porch is exposed to all elements (snow/freezing temps in winter as well as high humidity/rain in summer). Is this even an option?

The porch floor slightly slopes toward small drainage holes drilled into bottom wood rails along floor to allow water drainage when it rains, etc. We don’t want to these holes to get covered up, how can we have tile, or is this a bad idea? We love our porch and eat/sit on it everyday in the summer. Need a good-looking low maintenance option that can be swept easily (mulch, etc. is tracked into porch alot.) I can send photo if it will help. Thank you! Susan

Sorry I am tardy with my reply Susan as I have been out of town.

Ok..so we have a screened porch that you desire to have an upgraded covering over. You have joined many thousands of folks who have been on the «paint» Merry-go-round» and now you want off. I understand. First and foremost is if you desire to employ a Porcelain or Ceramic Tile as a floorcovering then you must move to the next «problem stage». The paint must be removed as it will be acting as a «barrier» to a proper and secure bond between the tile and the slab on grade. follow me? So this will entail either using a disc grinder (best and quickest way) or a chemical stripper to remove the offending paint layers. Either way Susan the goal is to return things back to where they were before the first coat of paint was applied. This will promote a solid and long lasting performing Tile install. With a small patio as you guys have the removal of the paint should only take a weekend to accomplish and then you can move forward with whatever you would like to have installed. There are now additional products that can greatly improve the quality of an install over cracks in slabs and with the «freeze/thaw» issues with a cold climate Region of the Country. The product that I am referring to is one called «Ditra uncoupling membrane» made by a Company named Schleuter. a very good product and a degree of insurance well worth the added cost, and besides the added cost is not all that much considering the bang you get for this cost with peace of mind.

Now the slope of your slab is in keeping with good planning on the original builders part. Having a positive (or negative depending upon how you are looking at it) slope away from the home is a necessary design element to keep things (always) running away from the home and the holes at the bottom plate of your porch walls keeps things running away from the slab as well as you have mentioned. Now the holes are very easy to reposition as the new flooring layer goes down there will still be room to «re»-drill new «weep holes» that are just a bit higher and will perform the same function that the lower holes did. No problem. Now, typically I like to try an add a bit more in the way of options in keeping with outside the box options. If you do not desire to grind away or strip away the existing paint layers then you might consider installing a rubber mat flooring that you can snap (looks like a puzzle piece assembly) that fits snuggly together and you can simply use a straight edge and razor knife to cut it in to the perimeter of the space around the defined walls, then you just cut out a 2″ semi-circle where the existing weep hole is located and moisture can be released right out the already provided places. You could just use a floor scraper that employs a 4″ razor blade and go over the entire space getting up all the loose paint and purchase a couple cans of «spray adhesive» and spray a loose amount of the material around just so that it will keep the mats securely held down onto the slab. This option can also buy you some additional time before making the hard (and more expensive) decision on a «hard surface» option. ok? That’s it Susan I hope this helps you with your project, feel free to return anytime.
