Gyproc Jointing is designed for embedding joint tape, filling gypsum board joints and hidden fasteners, and creating a smooth, crack-free surface ready for final decoration. It is ideal for interior walls and ceilings in dry lining systems where quality and finish matter.
There are standard (approx. 60-minute) and long-working (approx. 90-minute) formulas of Gyproc Jointing. These allow flexibility based on environment and project workflow, giving installers time to embed tape and finish joints properly before setting begins.
One 25 kg bag of Gyproc Jointing typically covers around 70 m² of drywall joints under normal conditions. Coverage will vary depending on joint width, depth, board size, and application technique.
No. Gyproc Jointing is intended for interior dry areas. It should not be used in locations with continuous moisture or outside exposure unless combined with appropriate moisture protection or systems designed for these conditions.
Gyproc Jointing uses a fine, high-quality gypsum base and controlled chemistry to reduce shrinkage and cracking during curing. The low-shrink formula and good adhesion ensure the finished surface remains stable and smooth over time.
Mix the powder slowly into clean water at approximately a 2.5-3 : 1 ratio (compound to water) until a smooth paste is formed. Apply, embed tape, finish the surface, allow to set, and sand lightly for a flawless result.
Gyproc Jointing conforms to EN 13963 (Jointing materials for gypsum boards) and is produced under controlled standards ensuring reliable quality and performance in suitable applications.
No, you should allow the compound to fully set and dry, then lightly sand before priming and painting. Ensuring proper drying and surface preparation results in a flawless final finish.
Store unopened bags in a clean, dry place off the ground and away from direct sunlight. The bag shelf life is typically around six to eight months. Exposure to moisture may reduce performance
If mixing ratios, application thickness, or substrate preparation are incorrect, the compound may shrink, crack or fail to adhere properly. Following manufacturer instructions ensures long‐term performance and a clean decorative finish.
