Stronger hold, smoother work: CasuCOL® in large-format tile adhesives

Cementitious dry mortar

Adding function to cement-based products

Avebe’s starch ether additives combine with cellulose ether to improve workability, plasticity, and consistency in cement-based mortars, tile adhesives, renders, and skim coats. Extended open times and slip/sag resistance reduce rework and shorten project schedules.

Dry-mix gypsum

Making a multipurpose material better

Starch ethers work effectively with other additives to enhance rheological properties in dry-mix gypsum products, improving workability and plasticity for plasters, fillers and finishing compounds.

Ready-to-use

Instant performance uplift

Ready-to-use plasters remove the complexity of on-site mixing. Adding CasuCOL® starch ethers ensures the formulation performs as intended without any intervention by the applicator, ensuring your products always work at their full potential.

Potato starch in plaster? It surprised me too, but it helps improve consistency, application and the final finish.

Testimonial

Just add some Potato for a World of Difference

“Plastering only becomes easy when you work with the right materials,” says Peter from Stucadoorsbedrijf Peter Jansen. “People often try to do it themselves, and it goes wrong. Then they ask me to finish the job with their materials. I never do that. The plaster people buy themselves just can’t compare to what I use – even if the bags and brands look identical.” Early 2024, Peter and his son Sietse participated in a photoshoot for Avebe’s building solutions. Peter: “We plastered several walls on set, which was captured by a film and photography crew.” Peter recalls: “When I heard that my plaster contained potatoes, I thought, ‘Excuse me?’ My colleagues were just as surprised. It’s not something you think about – that you could have potato starch as an ingredient in plaster materials.”
