Endurable pH Pencil

Application Instructions Moisten surface with distilled or ionized water Mark concrete with Endurable pH Pencil Wait 15 seconds Compare with color chart Product Information The Endurable pH Pencil is a reusable tool to determine the pH of concrete before the application of Endurable sealers, coatings, and dyes. It is important to test the pH of concrete before the application of decorative concrete products to confirm the pH is in the suitable range of 8 and 10. If the concrete falls outside of this range, it is necessary to mitigate the pH issue before proceeding with the use of decorative concrete products, such as sealers, coatings, dyes, etc. It is important to understand the basic chemistry of concrete and how that determines the proper pH level of concrete before the application of sealers, coatings, and dyes. When concrete is poured, the pH is upwards of 13. While the concrete remains wet while it is curing, the calcium hydroxide (or free lime) in the concrete mix
