Plastering Tape Expert+ 38 mm x 20 m — TAŚMA TYNKARSKA MN-05-350

Plastering Tape Expert+ 38 mm x 20 m is a woven reinforcement tape designed to strengthen plaster and render joints, prevent hairline cracks and improve the durability of internal and external wall finishes. The 38 mm width and 20 m roll length make it suitable for reinforcing seams, corners and transitions in plaster systems where cement or gypsum-based mortars are used. The tape is intended for use before finishing coats to ensure a stable, crack-resistant surface on walls and ceilings.

Advantages

The tape provides uniform reinforcement across joints and corners, reducing the risk of cracking and delamination in plastered surfaces. Its woven structure ensures good adhesion with cement and gypsum-based mortars and allows for easy embedding in base coats. The product's standard width fits common joint sizes and narrow profiles, while the 20 m length offers enough material for multiple repairs or continuous joint treatment. The tape is compatible with both interior and exterior plastering applications when used with appropriate mortars and finishing systems.

How to use

Ensure surfaces are clean, dry and free of loose material before application. Apply a base layer of the chosen cement or gypsum-based mortar over the joint or corner area. Embed the tape into the fresh base coat, pressing it flat and aligning it along the seam or corner. Smooth the tape into the mortar so that it is fully covered and level with the surrounding surface. Allow the base coat to cure according to the mortar manufacturer's instructions before applying finishing coats or paint.

Usage recommendations

For best results, use plastering mortars recommended for the substrate and follow drying and curing times. On exterior applications, ensure the chosen render and finish system are appropriate for weather exposure. Store the tape in a dry place and protect it from direct sunlight and moisture prior to use.
