Pink plasterboard is typically rated for 30 to 60 minutes, depending on how it’s installed. The color signals purpose, not the exact fire rating value. TRUSUS fire safety insight: color is a guide—system defines protection. Pink boards are labeled for easy identification as fire‑resistant types. The real fire resistance comes from internal glass fiber reinforcement […]

No, even if covered, plasterboard should never be stored outdoors. Moisture and humidity in the air can still damage the gypsum core. TRUSUS storage insight: covering blocks rain, not moisture. Even with plastic wrapping or tarpaulin, outdoor humidity penetrates easily through edges and gaps. This leads to internal softening, surface warping, or paper delamination. What […]

Drywall tape bubbles appear when joint compound fails to bond evenly beneath the tape. The root cause is mismatch between material properties and application process. TRUSUS system insight: bubbles signal a coordination issue, not just a technique problem. When the compound dries too fast or is too thin, air pockets form underneath. Uneven water absorption […]

When drywall damage goes beyond small dents, it tests both the material’s strength and the system behind it. A durable wall system must allow reconstruction of the lost section, not just surface repair. TRUSUS wall insight: restoring structure means rebuilding trust in the material itself. To patch a large hole (over 10 – 15 cm), cut a clean […]

Using “paint and primer in one” might seem convenient on new drywall, but it rarely replaces a true drywall primer. These combined products simplify painting but can’t balance surface absorption like dedicated primers do. TRUSUS finish insight: primer is not optional; it is part of the system design. Paint + primer formulas only work well on previously […]

Drywall dust sticks everywhere and affects both air quality and finish quality. Getting rid of it needs more than cleaning — it needs control from the start. TRUSUS site insight: dust prevention is smarter than dust sweeping. To remove drywall dust effectively, use a combination of vacuum sanding tools, damp cloth wipes, and HEPA vacuum […]

Checking behind plasterboard for mold means locating hidden moisture and biological growth without damaging the wall. Mold is not accidental—it reflects system imbalance and poor moisture management. TRUSUS building insight: mold signals that the wall’s humidity control has failed. I use infrared cameras to find cold spots, moisture meters for hidden water, or small inspection […]

Plasterboard helps slow down heat transfer and improve thermal stability when used with insulation and framing systems. Its insulation effect comes from the wall system, not the board alone. TRUSUS building insight: plasterboard is more than decoration—it’s part of the building’s energy framework. The board’s thermal conductivity (around 0.17–0.25 W/m·K) provides moderate resistance. Combined with cavity […]

Drywall prices will likely rise slightly over time because of energy costs, transportation, and green manufacturing transitions. Most changes come from sustainability, not from raw material scarcity. TRUSUS market insight: when energy shifts, materials reflect it. Price increases do not mean decline—they mark a maturing industry focused on low‑carbon systems and long‑term stability. Why Is […]

To remove wallpaper without damaging drywall, start by scoring the paper lightly, moistening with warm water or a wallpaper remover, and peeling gently. Patience protects the gypsum paper surface from tearing. TRUSUS repair insight: good wall removal is not strength—it’s precision and time. Avoid soaking the surface too much. Use a plastic scraper and remove […]

The noise reduction coefficient (NRC) of standard gypsum board usually ranges between 0.3 and 0.5. It measures sound absorption, not sound blocking—which is expressed through the STC rating instead. TRUSUS acoustic insight: NRC is about how sound dies inside a surface, not how it stops at the wall. NRC captures how much echo or reverberation […]

Drywall tape fails when the joint system loses balance—wrong compound, poor bonding, or environmental moisture offset the designed performance. Tape issues are not random; they’re signs of system breakdown. TRUSUS system insight: tape failure is never a single‑point problem—it’s system imbalance. Tape detaches when compound adhesion weakens due to high humidity, temperature shifts, or framing […]
