OmniBuild Pro Neutral Primer 5 Gallon is a Chemcraft conversion varnish primer designed for interior woodwork and MDF, so it prepares those substrates for finishing in a production-focused shop. The true 24 hour pot life allows a mixed batch of primer to remain usable for a full working day, which supports longer spray runs and reduces waste from prematurely expired material. Its high-solids formulation lays down a thicker film in each pass, building coverage quickly so fewer coats are needed to reach hiding power on wood or MDF. That same high-solids content also supports sag resistance during vertical or edge spraying, which helps maintain an even film without rework. As a neutral primer, it creates a consistent base color for subsequent Chemcraft topcoats, supporting predictable color development job after job.
OmniBuild Pro primer is described as easy to apply, so it supports straightforward spray application on interior woodwork and MDF without unusual technique changes. The primer sands easily and quickly, which reduces time at the sanding station and helps crews move parts efficiently from primer to topcoat. Its quick stack time allows primed parts to be handled and stacked sooner, supporting faster turnarounds and better use of rack space in a busy finishing area. As a conversion varnish primer, it is designed to sit under Chemcraft Chemlife 24 or Chemlife 24 Plus topcoats, helping the overall system perform as intended across interiors that rely on that finish family.
This Chemcraft OmniBuild Pro primer is intended for interior woodwork and MDF, so it supports casework, doors, panels, and trim that stay within indoor environments. The neutral base helps prepare varied MDF and wood substrates under a coordinated Chemcraft finish system, which matters when projects combine different components but expect matching topcoat appearance. When used with 117-24XX Chemlife 24 or 117-25XX Chemlife 24 Plus topcoats, the primer forms part of a dedicated Chemcraft system, helping maintain compatibility within that family. The 5 gallon size suits production-focused or shop-based finishing operations where multiple jobs draw from a single primer system over time.
The true 24 hour pot life conversion varnish primer allows predictable working time from mix through the end of the shift, which simplifies scheduling and reduces the need to discard partially used material. High-solids formulation builds film quickly, supporting consistent hiding on both MDF and interior woodwork with fewer passes, which matters on repetitive parts. Sag resistance limits downward flow on vertical spraying, so film stays more uniform and needs less corrective sanding. Easy application and fast sanding characteristics smooth the workflow from booth to sanding to stack, helping crews maintain throughput. Quick stack time then allows finished primed parts to move out of the way promptly, supporting a continuous production path into Chemcraft Chemlife 24 or Chemlife 24 Plus topcoats.
