MAS Deep Pour and Deep Pour X are different resin systems

Original MAS Deep Pour and MAS Deep Pour X should have separate comparison rows. Original Deep Pour uses three parts resin to one part hardener by volume and is intended for half-inch to one-inch layers, with the allowable depth depending on the amount poured. Deep Pour X uses a two-to-one volumetric mix and is designed around two-to-three-inch casting depths.

The difference changes both preparation and scheduling. Deep Pour X is deliberately slow enough that MAS discourages using it as the wood seal coat. Its instructions also permit much larger mixing containers than the original formula, so a generic 'MAS Deep Pour' batch rule would be misleading.

Match the full product name on both containers to the documentation. The weight ratios are different again—100:28 for Original and 100:43 for X—and neither is interchangeable with its printed volume ratio.

Plan the measuring and mixing stage

No complete mixing procedure was established in the sources below. Follow the current instructions supplied with the exact kit instead of copying a routine from another formula.

FAQ ≤1 gallon per mixing batch.

Allow for the whole cure schedule

Product working 3 h; cure 24–36 h at 70°F. FAQ gel 5.5 h for 150 g at 77°F; not a recommended 77°F shop setting.

The manufacturer FAQ distinguishes full cure of 5–7 days for a 0.5–1 inch casting at 77°F from the product page’s 24–36-hour cure headline. The FAQ test temperature is not permission to exceed the product’s 75°F workshop ceiling.

Working time, demolding and full service are separate decisions. Record room conditions and actual mixed quantity in your project notes, and do not use a hard surface alone as proof of complete cure.

Limitations & open questions

  • Product benefits say 1/2 gallon or 1 gallon while instructions use half/full 1.3 gallon kit.
  • Full-kit casting illustration does not override ≤1 gallon mixing limit.
  • Separate from 2:1 Deep Pour X.

A depth ceiling is only one condition. Verify total mixed mass, geometry, temperature and the exact kit revision before planning a pour. A smaller package of the same formula does not automatically change its operating limits.
