Crown Wallplast Filler (also known as Crown Wall Plast Skimcoat Filler or Crown Wallplast Cement Putty) is a white, cement-based, polymer-modified powder filler used to prepare interior and exterior surfaces for painting. Its primary function is to provide a smooth, durable, and crack-free base.

Primary Uses

Skimming/Smoothing Surfaces: The main use is to create a perfectly smooth, even, and matt finish over rough or uneven walls and ceilings before paint application.

Repairing Imperfections: It is excellent for patching and filling minor cracks, dents, nail holes, and pinholes in existing surfaces.

Base Coat Application: It acts as a base coat on various substrates to cover unevenness.

Enhancing Paint Adhesion: By providing a uniform and smooth base, it enhances the adhesion and longevity of subsequent paint layers.

Suitable Substrates

Crown Wallplast Filler is compatible with a wide range of surfaces:

Interior and exterior plasterwork

Brick and block walls

Concrete

Timber

Key Features and Benefits

Interior and Exterior Use: Its weather-resistant and breathable properties make it suitable for both indoor and outdoor applications.

Durability: The cement-based formula is designed to prevent cracks, flaking, peeling, and shrinkage, offering a long-lasting finish.

Excellent Adhesion: It bonds firmly with cement plaster, concrete, and masonry due to its cement-based composition and polymer modification.

Easy to Use: It has good workability, mixes easily with water to form a workable paste, and is easy to apply with a trowel or spatula.

Breathable: It can be used even if the walls still have some residual moisture.

Application Process (General Steps)

Preparation: Ensure the surface is clean, dry, and free from dirt, grease, and loose paint.

Mixing: Mix the powder with clean water to form a smooth paste (typically 2 parts powder to 1 part water by volume).

Application: Apply the filler using a steel trowel or spatula in thin, even layers.

Drying and Sanding: Allow each coat to dry completely (surface dry in about 1 hour, ready to sand in about 4 hours). Sand lightly to a smooth finish.

Finishing: Proceed with applying a primer and then the desired top coat of paint.
