Wall Putty / Skim Coat

The skim coat loses water too quickly after application, especially on highly absorbent substrates or under hot and dry conditions, resulting in difficult finishing, insufficient hydration, and reduced strength.

The mixed material feels dry, heavy, sticky, or difficult to spread, requiring excessive effort to apply and making it difficult to achieve an even layer.

The applied wall putty does not bond firmly to the substrate and may peel, flake, blister, or detach after drying or during subsequent painting.

Fine cracks or visible shrinkage cracks develop during drying or after application, reducing the appearance and durability of the finished surface.

The wet material slides downward after application, causing uneven thickness, waves, and difficulty in achieving a flat vertical surface.

The dried surface releases loose powder when touched or rubbed, resulting in poor surface strength and reduced adhesion of subsequent paint or coatings.

The finished surface contains trowel marks, ridges, grains, or uneven areas, requiring additional sanding and increasing labor and material consumption.

Small holes, bubbles, or surface voids appear during application or drying, affecting smoothness and becoming more visible after painting.

The mixed material thickens, skins over, or becomes difficult to level too quickly, leaving insufficient time for application, adjustment, and surface finishing.

The dried skim coat is either too hard to sand or too soft and powdery, making it difficult to obtain a smooth and uniform surface before painting.

The skim coat separates from the substrate or between applied layers, often becoming visible as hollow areas, peeling, or localized surface failure.

Different production batches show variations in water demand, viscosity, workability, setting behavior, or surface finish, making quality control difficult.
