What is the perfect pH level for concrete when gluing down carpet?

The ideal pH level for concrete when gluing down carpet falls between 7 and 9. This range is considered neutral to slightly alkaline, which is suitable for the adhesion process.

When pH levels are within this optimal range, the bonding agents in the carpet adhesives can effectively interact with the concrete surface, ensuring a strong and durable bond. If the pH is too low (acidic) or too high (too alkaline), it can negatively affect the adhesive properties, potentially leading to issues like delamination or failure of the carpet installation. Maintaining a pH level within the 7 to 9 range helps to achieve proper adhesion and overall longevity of the carpeted surface.

Conversely, levels outside of this range could compromise the effectiveness of the adhesives used, resulting in poor installation outcomes.
