Dry-mix gypsum additives:making multipurpose material better

The benefits of starch ethers aren’t limited to cementious dry mortar. They work with other additives like cellulose to make even greater gains: workability, plasticity, and other rheological properties. All of which make them an ideal additive to other construction compounds, including dry-mix gypsum.

Avebe gypsum additives

Gypsum is a versatile raw material. From wall and ceiling finishes to floor screed and sealing gaps, dry-mix gypsum compounds have thousands of applications – and including starch ether additives in the mix makes them more effective when professionals use them. These additives allow easier spreading and smoothing without losing gypsum’s lightweight or fireproof properties, letting you offer a superior product that remains compliant with building codes. Which makes life easier for your customers – and for the painting and decorating trades that come after them, too. Let’s see what Avebe additives bring to both plaster and filler.

Our starch ethers work in synergy with other additives like cellulose ethers and retarders to make a good product better by improving workability, improved adhesion to the substrate and other important rheological properties. This makes Avebe’s starch ethers an important part of gypsum based dry mortar formulations.

Finishing plaster additives: pure performance for a perfect look

When it comes to plasterwork, construction contractors of all sizes want a consistent result across large areas – sometimes thousands of square metres. A finishing plaster is the final ‘coat’ applied to the surface before painting and can be applied both manually and via spraying. It needs to be very smooth which outlines the importance of spreading it evenly.

Finishing plaster

Avebe’s finishing plaster additives makes this happen. Starch ethers work with – or replace other additives to increase water retention, giving workers more open time to build the perfect smoothness – while making the hard work of application less hard.

Additives for finishing plasters span a range of job types, too, with grades available for blending with various gypsum mortar formulations. Thin-set or thick-applied, perfect surface or rough, the right starch ether additive makes your product fit for every market you operate in. It means satisfied customers with higher productivity – and more sales for those who answer their needs.

Filler additives: flawed to flawless, from small gap to large opening

Avebe’s range of dry-mix gypsum additives extends to fillers: the thousand and one jobs on every project that need sealing and covering. And while they use the same trade skills, cracks and joints benefit from a different additive – which is why Avebe has a range.

The benefits

The benefits of using gypsum boards in configuring internal spaces are many. Once the boards and in place they need to be pre-prepared for the finishing coats. Here, joint fillers are needed. There are two primary methods of filling joints, directly or with the help of paper tapes.

In both cases, it is important to develop the right consistency and impart a set retarding function into the design of your formulation. Paper tape systems require that the fillers be able to adhere to both gypsum and paper. Direct system requires for higher flowability to be able to fill gaps, yet, be able to stay in place once it has penetrated the gap (anti-sag). Our starch ethers can cater to both these methods.

Additives for crack fillers and joint fillers give your customers the same advantages as with other starch ethers. A more workable and consistent product at the job site. A filler that’s easier to apply and won’t dry out before the job’s done. That retains its shape once applied, without deforming and losing integrity. And again, as with other starch ether additives, you don’t need a high blend of them to see great benefits. If the job needs a filler, there’s a Avebe starch ether additive for it.
