How much concrete can I demolish with a box of Dexpan?
A standard 44lb. box will cover approximately 35 lineal feet of drilled holes, which can be used in a standard pattern to remove 60 cubic feet, or 1.7 cubic meters, of concrete. A 11lb. bucket will cover approximately 9 lineal feet, or ~16 cubic feet (.45 cubic meters). Dexpan is recommended for projects with a depth of at least 8 inches.
Which Dexpan should I use?
Use the ambient temperature of the area surrounding the rock and compare it to the temperatures listed on each type of Dexpan. A local weather forecast should be enough to determine the appropriate type of Dexpan. For Temperatures between 77-104° F (25-40° C), use Dexpan #1. From 50-77° F (10-25° C), use #2. And for 23-50° F (5-10° C), use #3.
When should I pour Dexpan?
The best time to pour Dexpan is the morning after you drill the holes, immediately after combining the product with water. Doing this as early as possible will allow Dexpan to work throughout the day.
Dexpan pushed itself out of its hole! What went wrong?
We refer to Dexpan pushing itself out of the drilled hole as a 'blowout', and it can occur for a few reasons. The most common is when the project does not have adequate expansion space. Be sure that there is an empty area next to the rock at least as long as the depth of the drilled holes so that Dexpan has somewhere to push the rock. Blowouts may also occur due to high temperatures (especially when using the wrong Type of Dexpan), large hole diameters, and using Core Bits to drill holes.
