Decorative MgO Board Edge and Joint Planning Guide

Decorative Mgo Board edge and joint planning should begin with the room interface, not with a face sample alone. Senchen’sDecorative Magnesium Oxide Board for Interior Walls uses high-purity magnesium oxide (MGO), magnesium chloride, and a blend of natural minerals. The product is a dense, rigid board that serves as both a structural base and a decorative surface. The face, exposed edge, joint intent and backing conditions should be reviewed together before a sample becomes a purchase line.

Fix the design intent before edge details

Write down what the interior wall needs to look like and where the board stops. A full-height feature wall, a small return, a column, a service opening and a transition to another finish create different edge questions. Include an elevation or marked-up photograph so the supplier can see the boundary being discussed.

Use this first brief:

• room or elevation reference;
• visible face and design direction;
• board area and layout direction;
• locations where the board ends, turns or meets another finish;
• expected maintenance or access conditions; and
• the date by which a sample or configuration response is needed.

The purpose is to make the sample review specific. A visually attractive face does not settle how the board will terminate at a corner, opening or adjacent material.

Define exposed edge and panel termination

An edge plan should identify every place where the board edge can be seen or must be concealed. Mark external corners, internal corners, returns, door or window openings, service panels, floor and ceiling lines, and transitions to paint, tile, metal or another board.

For each condition, ask the project team to choose the design intent:

Do not turn these questions into an assumed Senchen edge profile. They are the project inputs needed to review the actual board configuration.

Plan joint language with the room

Joint planning connects visual rhythm to construction coordination. State whether the design expects aligned joints, a deliberate grid, a quiet transition or a feature line. Note the drawing scale and the viewing distance that will be used for sample approval.

Then separate the visible design question from the installation question. The sample can show the face and a proposed joint expression; the supplier and project team still need to review board dimensions, edge treatment, backing, movement conditions and the adjacent finish before accepting a detail.

Keep the following together:

1. elevation or layout drawing; 2. face sample and product identification; 3. edge and joint sketches; 4. backing or support assumptions supplied by the project; and 5. open questions for the configuration review.

This prevents a joint drawn for one board size or backing condition from being copied into a different room without review.

Keep backing and installation system open until project review

The product is a dense, rigid board that serves as both a structural base and a decorative surface. That role makes backing and adjacent construction important to the interface discussion, but it does not establish one universal backing, fastener, adhesive, joint width or installation system.

Ask the supplier to review the proposed board with the actual substrate, support spacing, openings, exposure and finish direction. If the project has a preferred installation method, provide it as a design input and ask which parts of the board configuration need confirmation. Do not publish a generic method as if it were a Senchen installation specification.

Inspect the sample at the real interface

Sample approval is stronger when it includes a corner, return or transition mock-up rather than a face swatch only. At review, compare:

• face appearance under the intended room light;
• visible edge at the planned termination;
• joint line and alignment with the elevation;
• relationship to the adjacent material; and
• any backing or support condition represented in the mock-up.

Record which elements are approved, which are provisional and which need a revised drawing or supplier response. Visual inspection can confirm the shown sample; it does not establish an unshown installation system or performance result.

Copy-ready decorative MgO edge and joint brief

> Product family:Decorative Magnesium Oxide Board for Interior Walls >Composition reference: high-purity magnesium oxide (MGO), magnesium chloride, and a blend of natural minerals > Room/elevation: [drawing or photo reference] > Visible face: [describe design direction] > Edge conditions: [corners, openings, returns, floor/ceiling, transitions] > Joint intent: [aligned, grid, feature line or other described intent] > Backing/substrate: [project condition or review request] > Adjacent materials: [list] > Sample/mock-up requested: [describe interface to show] > Open configuration questions: [list finish, edge, backing and installation items]

Send the brief with the elevation and ask the supplier to mark every changed assumption in the returned configuration response.

Request a decorative board interface review

Share the room reference, face direction, edge conditions, joint intent, substrate and sample requirements through the Senchen Decorative Magnesium Oxide Board product page or the Senchen contact page. This keeps visual approval and interface coordination on the same product line.

FAQ

Is a face sample enough to approve a decorative MgO board?

No. Review the visible face together with corners, openings, exposed edges, joint intent, adjacent finishes and the project backing condition.

Does the product description define one universal joint system?

No. The dense rigid board role explains why the interface matters, while edge, joint, backing and installation details require project-specific review.

What should a supplier receive with an edge question?

Send the elevation or marked-up photo, face direction, every termination condition, joint intent, substrate or backing information, adjacent materials and the sample requirement.
