Fill n’ Finish Ultra-Thin

When the job calls for the highest precision, Fill n’ Finish Ultra-Thin is the obvious choice. The ultra-thin formula reaches areas where other fillers fall short.

The product penetrates deep into hairline cracks, pores and delicate wood structures. It strengthens the material from within and creates a stable base for further work. The result is a durable repair with minimal impact on the appearance of the surface.

Many use Fill n’ Finish Ultra-Thin for fine wood products, instrument making, model making and arts and crafts, where every detail matters. The self-levelling formula gives a flexible, durable and crystal-clear fill with a glass-like finish.

For best results – use together with GluBoost Accelerator

The Fill n’ Finish system cures slowly. GluBoost therefore recommends using the product together with one of the company’s accelerators. Apply thin layers and cure between each layer. This lets you build up the repair quickly while keeping full control over the result.

After curing you get a hard, crystal-clear and stable material that still retains its flexibility. The combination of strength and flexibility is perfect for repairs where both durability and appearance are important. You can then sand the surface in stages, from coarse to fine grit, and finish by polishing to a high gloss. The result blends naturally into the surrounding surface.
