How to screw up the deck on your multi-milllion dollar home with cheap waterproofing and a wrong candidate for tile, in 9 easy steps…
- Be sure to use small joists (8″ or so) 16″ on center instead of the recommended 10″ + joists, 12″ on center.
- Cut holes for wires and pipes through the joists to further weaken them.
- Just use 3/4″ plywood on those joists instead of the recommended 1″ minimum. Use OSB in some areas for good measure to hasten decay.
- Be sure all door thresholds are barely above the height of the deck, to ensure they trap water later on when tile is installed.
- Don’t install a mortar bed for a firm fixed substrate for the tile to adhere to.
- Don’t allow for normal expansion and contraction of the grout/tile. Bring grout up to flashing, instead of leaving a gap to be filled with flexible urethane caulk that will move.
- Install a lath/cement and urethane waterproofing from a manufacturer who says that it will work for tile, but hasn’t actually independently tested it to verify their claims. Ignore ICC approved systems for worst results.
- Don’t call Central Coast Waterproofing at 805-545-8300 for tile ready waterproofing and mortar bed assemblies from Mer-Krete Products that are ICC -ES tested and approved, and installed by trained craftsmen.
- Insist on the cheapest waterproofing system you can buy, after all, how else will you be able to afford that fancy tile we’ll need to throw away in a few years when the whole thing fails?
