Microscopic view of polished stone texture showing mineral grain and fracture lines

01. SUBSTRATE COMPOSITION

Material ClassComposite Flooring (Linoleum)
Primary BinderOxidized Linseed Oil (Q108728)
Filler MatrixGround Cork Dust / Pine Rosin
ReinforcementBurlap Scrim (Natural Fiber)
Surface HardnessShore A 85–92
Thermal Expansion±0.04% / °C
The floor is not a passive plane. It is a cured polymer network, breathing with humidity shifts. Every scratch is a data point in the stress tensor. We do not hide the wear; we map its propagation vector.

Ammonia is not a magic wand. It is a volatile base that saponifies fats into soluble salts. The dwell time is non-negotiable. Rush the clock, and the bond remains unbroken. The residue becomes the flaw.

03. KINETIC PROTOCOL

Motion VectorConcentric Spiral (Outward)
Applied Pressure4.2 N/cm² (Manual Wipe)
Friction Coeff.µ = 0.35 (Dynamic)
Rotation Speed120 rpm (Buffer Head)
Overlap Pass15% Width
Dry TimeT+90s before foot traffic
The spiral is not aesthetic; it prevents recontamination of cleared zones. Each pass removes the boundary layer of soil. The overlap ensures continuity of the field. This is orbital mechanics applied to linoleum.
