Technical Specification

Sub-millimeter tolerances and absolute containment.

A bad seam is visible from across the room; a perfect seam doesn't exist to the eye. We enforce rigorous moisture mapping, archival substrate sealing, and strict dust containment on every site.

<0.2mm

Seam variance limit

100%

HEPA air containment

2x

Substrate primer pass

Surface Preparation

Zero-lap methods vs standard painting

Meticulous Primer Coats

We prep twice so we only have to hang once, locking in plaster porosity to ensure uniform adhesion without blistering.

Substrate Smoothing

Full skim coating and sanding under 500-watt raking lights to eliminate drywall telegraphing before hanging expensive materials.

Archival Wallcovering Seam Standard

Pre-installation moisture mapping and substrate sealing prevent seam tension and edge curling on delicate grasscloths and heavy commercial vinyl.

Job Site Protocol

Floor-to-ceiling negative air containment

Drop cloths stay down until the final inspection is signed off. We seal all HVAC vents and deploy continuous HEPA dust capture during every removal and sanding phase.

Commercial facilities and residential interiors remain immaculate throughout the schedule, protecting adjacent finishes and furniture.

Specifier Trust

Verified by design professionals

When we specify imported hand-painted grasscloth, All Season is the only crew we trust on site. Their seam work is invisible.
