FAQ
What surfaces can Drybase be applied to?+
Drybase membrane can be directly applied to brick, blockwork, concrete, plasterboard and timber. However, it's crucial to ensure the substrate is clean, dry, and free from loose particles before application for optimal adhesion and performance.
How much area does one roll cover?+
One standard 2m x 10m roll of Drybase membrane covers approximately 20 square metres when applied at the recommended width. Precise coverage depends on overlaps and cut-offs, so careful measurement is essential.
Does Drybase require any surface preparation?+
Yes, thorough surface preparation is vital. The substrate must be clean, dry, and free from loose mortar or paint. Light abrasion with a wire brush or sandpaper can improve adhesion. Consult the manufacturer’s guidance for detailed prep instructions.
Is Drybase suitable for use in bathrooms?+
Drybase is generally suitable for bathroom applications but must be installed correctly, adhering to all manufacturer guidelines. Ensure adequate ventilation and consider using a breathable paint finish to further enhance moisture control.
How does Drybase compare to traditional damp-proof courses?+
Unlike traditional DPCs that rely on impermeable barriers, Drybase is breathable. This allows moisture vapour to escape from the wall, preventing condensation buildup and reducing the risk of secondary damage. It's a more proactive approach to damp protection.
What tools are needed for application?+
You’ll need a utility knife, a measuring tape, a brush or roller for applying adhesive (if using), and a straight edge for accurate cuts. A spirit level is helpful for ensuring consistent membrane placement.
Can Drybase be applied to exterior walls?+
Drybase can be used on external walls as part of a complete waterproofing system, but it’s crucial to correctly seal any joints and overlaps with appropriate sealing tape recommended by the manufacturer.
What is the typical lifespan of Drybase?+
With proper installation and maintenance, Drybase membranes have a lifespan of 20-30 years. Regular visual inspections are recommended to ensure continued effectiveness and address any potential issues proactively.
Does Drybase affect brickwork breathability?+
Drybase’s breathable membrane allows for the natural evaporation of moisture from brick, which is crucial in preventing damp problems. It doesn't impede the brick’s ability to ‘breathe’ like a traditional impermeable DPC.
What happens if I need to make repairs to Drybase?+
Small areas can be patched using additional Drybase membrane and adhesive, following the manufacturer’s guidance for cutting and applying. Larger damage may require professional assessment and repair.
