Polyurethane is the workhorse clear topcoat for interior woodwork: a film-forming resin that cures to a hard, continuous layer over bare or stained wood and takes the abrasion, spills and handling that the wood underneath cannot. Minwax lists this finish for interior projects such as woodwork, furniture, doors, cabinets and floors.

The semi-gloss sheen sits between satin and full gloss. It reflects enough light to read as a finished, slightly lustrous surface and to wipe clean easily, without the mirror return of a gloss coat that telegraphs every sanding scratch and dust nib. On trim and cabinetry it is the usual compromise when a satin coat looks too flat next to painted work.

Polyurethane is applied in thin coats over a clean, sanded, dust-free surface, with a light scuff-sand between coats for mechanical adhesion. Two or more coats are normal, with the final coat left to harden before the surface is put back into service. It can go over cured oil-based wood stain or directly onto sanded bare wood.

Key Features

• Clear protective topcoat for interior wood, applied over bare or previously stained surfaces
• Semi-gloss sheen: a moderate light reflection that hides minor surface imperfections better than gloss
• Cures to a hard film that resists scratches, scuffing and household spills
• Minwax offers the finish in warm semi-gloss, gloss, satin and ultra flat sheens, so sheens can be mixed across a job from one product family
• Clear, non-pigmented film that lets grain and stain colour show through
• Brushed, wiped or pad-applied in thin coats, with a light sanding between coats for adhesion
• Contractor-size container suited to floors, full trim packages and cabinet runs rather than single small repairs
• Compatible over cured Minwax oil-based wood stain as part of a stain-and-topcoat system
