Question: Should I tape plastic or cardboard directly to my acid stained and sealed floors for protection during construction?
Answer: Do not apply tape of any kind to acid stained and sealed floors. Tape adhesive forms an unnatural bond with concrete sealers so strong that it will actually rip the sealer and sometimes the stain completely off the floor when removed. Tape damage will at best leave a very unattractive adhesive line on the surface that will require stripping. Tape can be applied safely to raw or acid stained concrete to create design elements on the floor. To protect after sealing from construction damage, overlapped cardboard or masonite are effective alternatives. Keep in mind that minor scratches and marks will be addressed by the application of the second sealer coat, especially when using our Sprayable Satin Finish or AC 1315 High Gloss Sealers. Solvent-based sealers have “self-healing” properties if you will that are very helpful in the construction process. Apply 2-3 thin coats of either residential or commercial wax for the final finish and enjoy.
