DRYLOK Fast Plug is a fast-setting hydraulic cement that sets in just 3-5 minutes, preventing water from flowing, even under pressure, through cracks and holes in concrete and masonry structures. It's ideal for sealing floor and wall joints, patching settlement cracks and holes in masonry walls, and anchoring metal to masonry. Similar to mortar, it sets and hardens extremely quickly.

A: Shiva - No problem at all. DRYLOK® Fast Plug must be mixed in small batches due to the fast-setting nature of the product. Doing your project over several days will not be an issue. Thank you for choosing DRYLOK®

Answer This Question
A: Darren - That is not an application for DRYLOK® Fast Plug. It's not designed as a surface coating, it's designed for application in holes or cracks. Applying in the manner you are asking about will be a failure.

A: We suggest waiting 7 days before applying latex based coatings such as DRYLOK® Waterproofer. If you need a quicker application, you can apply DRYLOK® Wet Wall Primer once the ph level is 13 or below.
