About the product
Aguaplast Rellenos is Beissier's high-performance powder filler formulated to fill deep cracks, large holes, and areas with material loss in interior walls and ceilings. Its specific granulometry allows for application in thicker layers than finishing fillers, offering great final hardness, minimal shrinkage, and excellent sanding capability. Ideal for structural repairs prior to fine finishing. Available in 1 kg and 5 kg.
What jobs is it ideal for?
- ✓ Filling deep cracks and large holes in walls and ceilings
- ✓ Reconstructing areas with material loss (impacts, chases, core samples)
- ✓ Repairing moldings and decorative plaster or gypsum elements
- ✓ First leveling coat before fine finishing with Aguaplast Standard
- ✓ Repairs requiring greater thickness than finishing putties can accommodate
Why choose Aguaplast Rellenos
- ✓ Allows for greater thickness than finishing filler — the specific granulometry allows for filling areas with significant material loss that Aguaplast Standard cannot cover in a single coat
- ✓ Great final hardness — the cured filler is hard and compact, resisting aggressive use and sanding without sinking or crumbling
- ✓ Minimal shrinkage — does not shrink significantly upon drying; the filler maintains the applied volume, avoiding the need for multiple coats to compensate for shrinkage
- ✓ Excellent sanding capability — despite its hardness, it sands well with sandpaper or a sander to achieve a finish flush with the original wall
How to prepare and apply — in 4 steps
- Prepare the substrate: clean, sound, and free of dust and poorly adhered parts. Moisten the substrate before applying to improve adhesion.
- Mix with water according to package instructions until a consistent and homogeneous paste.
- Apply with a spatula or trowel completely filling the area. For deep fills, apply in layers, allowing each to dry between applications.
- Sand and finish: once dry, sand until level and apply Aguaplast Standard or a finishing filler for the final thin coat before painting.
For interior use only. Clean tools with water before setting.
