Drywall partition systems are widely used in residential and commercial interior construction across the Balkans. The joint between two plasterboard sheets is the weakest point of the finished wall surface — prone to cracking when the building settles, experiences temperature cycling, or is subject to any vibration. Self-adhesive fiberglass mesh tape is the professional reinforcement method for all drywall joints, replacing paper tape with superior strength, moisture resistance, and dimensional stability.
Ensure plasterboard is properly fixed to subframe with no gaps or flexible areas
Tape all board joints, internal corners, and external corners with self-adhesive fiberglass mesh tape
For external corners: apply fiberglass tape over corner bead; or use mesh tape directly over back-to-back corner
Apply joint compound (filler) over tape; feather edges a minimum 75mm either side of the joint
Allow to fully dry; sand lightly; apply second coat if required
Allow full cure; sand smooth; apply primer before paint or final finish
50mm tape width centred on joint; 100mm tape for wider coverage and internal corners
Fiberglass mesh tape does not require embedding in wet joint compound before application — self-adhesive
Superior moisture resistance vs paper tape — suitable for bathrooms, kitchens, and laundry areas
High tensile strength mesh bridges micro-movement at board joints without cracking
No mould risk — fiberglass does not absorb moisture or support mould growth
Using paper tape in wet rooms — paper absorbs moisture, de-bonds, and supports mould
Applying only one coat of joint compound — tape edge shows through paint after drying
Not taping internal corners — internal corners crack under even minor settlement without reinforcement
Applying tape to poorly fixed plasterboard — reinforcement doesn't help if boards are moving at fixings
Insufficient feathering of compound at tape edges — visible ridge shows through finished surface
Paper tape vs fiberglass mesh tape — which is better?
Fiberglass mesh tape is stronger, moisture-resistant, and self-adhesive. Paper tape requires embedding in joint compound before application and is not suitable for any wet area. Fiberglass tape is the professional standard.
What width for drywall joints?
50mm tape is standard for flat joints. Use 100mm tape for internal corners (fold in half lengthwise, or apply flat for wider coverage) and for wider or uneven joints.
Can fiberglass mesh tape be used for exterior applications?
Yes, in exterior systems the tape must be covered with at least 2mm of alkaline-resistant base coat. It is not suitable as an exposed surface material.
