Is It Okay to Use Paint with Primer on New Drywall?

Jun 01, 2026

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 […]

How to Get Rid of Drywall Dust After Sanding?

May 29, 2026

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 […]

How to Check Behind Plasterboard for Mold?

May 28, 2026

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 […]

Does Plasterboard Help Insulate?

May 27, 2026

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 […]

Will Drywall Prices Go Up?

May 26, 2026

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 […]

How Do You Remove Wallpaper Without Damaging Drywall?

May 25, 2026

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 […]

What Is the Noise Reduction Coefficient of Gypsum Board?

May 22, 2026

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 […]

What Causes Drywall Tape to Fail?

May 21, 2026

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 […]

Which Way Should Drywall Run on a Ceiling?

May 20, 2026

Drywall should always run perpendicular to the ceiling joists. This direction creates stronger joints, spreads load evenly, and minimizes the risk of cracking or sagging over time. TRUSUS system insight: direction defines structure—perpendicular layout means stable, long‑lasting ceilings. Running boards across the framing ensures every seam is fully supported and stress is distributed evenly. This […]
