A Mock-up (installed sample area) helps set the standards for installation quality by allowing the architect to inspect a small area of installed flooring before full installation goes ahead. This helps get everyone on the same page bringing together industry standards and client expectations. For example, where resilient flooring (vinyl, rubber, linoleum) is specified, one inside and one outside corner, one vertical and one horizontal seam plus colours and patterns (within reason) must be shown. Having client, consultant and installer set the standards bar together removes the concern that ‘perfect’ (not possible) may become the expectation later on. It also leaves a sample area in place for all to refer back to throughout the project should a question of quality be raised.
Heat welds for non-directional vinyl sheet goods should have the following general characteristics:
- Even width, smooth (not rough) with the adjoining plane, continuous without gaps or cracks to the bottom of the cap strip, have color matching welds with the vinyl flooring, have no deep pockets at inside corners.
- Mitred (welded at corner) Inside Corners.
- Outside corners can be installed either mitred (welded at corner) or Butterfly 'V' Plug, depending on manufacturer requirement and consultants specification.
- Cap strips strips are continuous around the outside corners.
- No bubbles
Note: Welding styles and characteristics change depending on the flooring product (linoleum, rubber, vinyl). Manufacturers installation guidelines must be reviewed carefully.
