Frequently Asked Questions (FAQ)

Is PlasterFusion Pro suitable for load-bearing repairs?

While PlasterFusion Pro provides extremely high bond strength for cosmetic and structural *adhesion* (like securing heavy moldings), it is not a substitute for professional structural engineering in load-bearing wall or ceiling failures. Always consult an engineer for major structural issues.

Can it be used on damp surfaces?

For optimal results, surfaces should be clean, solid, and free of loose material. It can be applied to slightly damp (not wet) substrates, but full curing requires a dry environment. For constantly damp areas, ensure proper ventilation during and after application.

What is the shelf life?

When stored in its original, unopened container in a cool, dry place (between 10°C and 25°C), MasterCraft PlasterFusion Pro has a shelf life of 18 months from the date of manufacture.

How do I achieve the smoothest finish?

For seamless repairs, apply slightly proud of the surface. Once it has set firm but is not fully hardened (typically after 1-2 hours), it can be easily smoothed with a damp knife or sanded to a featheredge. It accepts all standard water- and oil-based paints after full cure.

Why is this considered the best glue for plaster repair?

It combines the gap-filling properties of a filler with the tenacious, flexible bond of a high-strength adhesive. This dual-action performance, along with its ease of use, non-shrink formula, and professional-grade durability, makes it the preferred, all-in-one solution for tradespeople who cannot afford call-backs or failed repairs.
