Bycol Dark - Tasmanian Supplier

Diggers Bycol Dark is a professional-grade, air-entraining plasticiser specifically formulated to improve the workability and finish of plaster and cement mixes. By acting as "liquid ball bearings" within the mortar, it creates a creamier, more cohesive consistency that is easier to apply and level. The "Dark" variant features a specialised resin designed to achieve an exceptionally smooth, polished finish, making it the premier choice for professional steel trowelling and fine rendering.

Bycol Dark is widely used by plasterers and bricklayers to compensate for poorly graded sands, ensuring a consistent texture and superior adhesion. Its unique formula reduces water "bleeding" and segregation, resulting in a more durable finish with a significantly lower risk of shrinkage cracking. The distinct dark tint also allows for easy on-site identification, ensuring quality control across every batch.

FAQ's​

What is the difference between Bycol Clear and Bycol Dark?
While both are air-entraining plasticizers that improve mix workability, Bycol Dark contains a special resin designed specifically for plasterers to achieve a much smoother finish. Bycol Clear is typically used for general brickwork mortars and concrete.

Why is the product tinted dark?
The dark tint serves as a visual indicator on-site, allowing tradespeople to easily confirm that the plasticizer has been added to the mix for consistent quality control.

What is the recommended mixing ratio?
Usage amounts depend on the sand type, with recommendations for different sand grades typically outlined in the product technical data sheet.

Can Bycol Dark be used with poorly graded sands?
Yes, one of its primary benefits is compensating for "hungry" or poorly graded sands. It acts like "liquid ball bearings" to improve the flow and cohesion of the mix even when the sand quality is inconsistent.

Does using this product help prevent cracking?
Yes. Bycol Dark reduces segregation and bleeding (water rising to the surface), which increases the flexibility of the render and lowers the risk of shrinkage cracking.
Is it suitable for steel trowelling?

Absolutely. Its specialized resin formula is engineered to provide the lubrication needed for steel trowelling, enabling a highly polished, professional-grade surface.
