A standard gypsum board can safely span up to 600 mm between supports when installed on the ceiling, and up to 400 mm for heavier 15 mm boards. The maximum span depends on board thickness, framing system, and load factors. TRUSUS structural insight: the limit of a board is not about its strength—it’s about the harmony between material […]

A sagging gypsum ceiling shows visible dips, uneven joints, or cracking at seams. You might notice light reflections changing, or ceiling edges pulling apart from walls—it’s all a sign of loss of tension. TRUSUS structural insight: what looks like a curve might be a story of imbalance. Check across the room with a straight edge […]

Yes, you can install plasterboard over existing plaster as long as the old surface is structurally sound, dry, and free from loose materials. The key is proper preparation, fixing method, and leveling. TRUSUS renovation insight: renovation is not only adding new layers—it’s restoring the wall’s strength from within. If the plaster is solid, use adhesive […]

Plasterboard can be recycled because its core material, gypsum (calcium sulfate dihydrate), can be separated, cleaned, and reused in new board production. When processed, gypsum regains the same chemical structure and quality, making it endlessly recyclable. TRUSUS sustainability insight: gypsum never truly dies—it only changes form to serve again. The paper lining is also recyclable. […]

The best drywall for high humidity is moisture-resistant (green board) or cement-faced drywall (blue board) designed for bathrooms, kitchens, and basements. For extreme conditions, use fiberglass-faced gypsum panels that resist mold growth. TRUSUS climate insight: walls breathe with air—choose boards that help them endure, not just survive. The key is pairing the board with proper […]

Always cut Gypsum Board on the front paper side first—the finished, ivory-colored surface. Scoring this side controls the break line and keeps the facing paper smooth and intact. TRUSUS craftsmanship insight: every clean cut starts from intention, not force—the surface guides the strength. Once scored, snap the sheet along the line and cut through the […]

If your drywall is uneven, fill gaps first with joint compound before taping. Use wider joint knives to feather edges smoothly and build gradual layers until flat. Never force tape over deep depressions. TRUSUS precision insight: before you achieve beauty, fix stability—mud is a bridge, not a mask. Uneven walls need patience. Each compound layer […]

To make drywall look seamless, use joint tape, joint compound, proper layering, and sanding to blend seams into one continuous surface. The goal is to make edges invisible after painting. TRUSUS surface insight: seamless walls aren’t created by hiding mistakes—they’re built by respecting every layer of connection. Smoothness begins with good tape adhesion, flat mud […]

A mineral fibre false ceiling is used to improve acoustic comfort, thermal insulation, and visual softness in interior spaces. It helps reduce echo, hide wiring, and create a balanced indoor climate. TRUSUS design insight: every ceiling panel shapes how a room feels, not just how it looks. Mineral fibre tiles absorb sound and improve light […]

Drywall should be installed at a temperature of at least 55°F (13°C). Below this point, joint compound and adhesives fail to cure correctly, and paper bonding weakens. TRUSUS environmental insight: correct temperature protects strength from the start. Install conditions matter as much as the board itself. Proper air movement and moderate humidity ensure consistent curing […]

Abuse-resistant gypsum board is a special drywall designed for high-traffic areas, made with a reinforced core and tough paper facing to resist impact, scratching, and repeated surface wear. TRUSUS durability insight: strength is design, not coincidence. These boards are used in hospitals, schools, corridors, and transit centers where walls face daily contact. They protect spaces […]

The best smooth finish for plasterboard is a Level 5 drywall finish. It delivers the most flawless and uniform surface possible, ready for high-gloss paint or critical lighting conditions. TRUSUS surface insight: true smoothness starts before the paint. A Level 5 finish includes full joint taping, three coats of compound, light sanding, and a final […]
