Cement is the most used construction material within a range of applications. A key part of standard dry mortar is cellulose ether. It helps retain water for curing, improves workability when applying, thickens for stability. In today’s market, Avebe’s starch ether additives in combination with cellulose ether take those existing benefits – and add further functionality.
Small volumes of starch ether added to cementious dry mortar change mortar rheology further. Starch ethers work in synergy with HPMC, MHEC and polymer powders. A small amount starch ether improves workability, sag and slip resistance, supports water retention, and improves open time while reducing stickiness.
And staying workable longer, across a broader range of operating temperatures – with binding and adhesion higher in every case. Meaning your customers can put in more productive hours each day and wrap up projects sooner. Here are Avebe’s construction additives for dry mortar – there’s one for every task.
Tiling takes time. And adding some starch ether improves the open time – which means greater customer loyalty to their preferred tile adhesive. Just add one of Avebe’s starch ethers to your tile adhesive formulation and watch performance rise with customer satisfaction.
Current trend is larger tiles. With the arrival of the Very Large Format Tiles (VLFT), a new set of requirements arises such as a longer open time to allow workers to move the VLFT into position. Our starch ether additive lets you create tile adhesives that offer a longer open time, without the slip risk – turning T-grade adhesive into TE-grade. That allow more water mixing, but without being prone to over-thickening. That add workability such as better spreadability for improved trowelling and tile surface coverage, but without losing adhesion strength.
And all compliant with EU and other building and construction standards. Adding starch ethers to your tile adhesive formulation gives you a product with better properties for greater market appeal. Professional tilers appreciate a CTA that helps them get a job done faster and better.

Get in touch for the best formulationMortar-based surfacing carries its own pain points – and these plaster additives answer them. Starch ethers enable easier application, less deformation, and greater open time when skimming and rendering, giving trade professionals performance characteristics they’ll value site after site.
For plasters, starch ethers give your product the ideal consistency, leading to a ease of application. Two time-consuming parts of the job – initial spreading and pre-adhesion smoothing – take up less time, while longer open times give the option to handle larger areas in one go. And when rendering, the same characteristics deliver easier pumping, without losing open time. In both cases, sag problems are far lower than with standard mortars. Meaning their productivity is your profit.
Construction customers demand ever-higher fit and finish standards: symmetry, surfacing, and uniformity. Professionals find them a lot easier to deliver if the mortars they use are more workable, giving consistent results without being harder to use or reducing working time. Avebe smoothing compound additives, also known as skim coats or ‘putty’ let you offer that premium smoothness to your market.
Smoothing compounds are thin layers of dry mortar specially made to create a smooth finish. The final finishing touch is very important as this is the final visual presentation.
In order to create a smooth surface, the skim coat must have low stickiness so as not to leave marks or pull-out chunks from the surface when the trowel is removed. The skim coat formulation must also be “flowable” enough to help trowel lines self-smoothen and skim coats must be easy to apply (workability). An important mechanical property for skim coats is the ability to retain water in the coating to allow the cement to fully hydrate and develop strength.
Avebe Starch Ethers help provide all the key design parameters needed to make a high-performance machine or manually applied skim coat. Making gypsum compounds easier to apply a consistent finish at all thicknesses, across a range of surfaces. It takes less work to get a top-quality result, increasing productivity for the people who use it and making every hour more productive. And smoothness doesn’t carry a cost. Adhesion stays up while sag risk stays low, meaning your product performance can be increased without any downside.
As cost of application goes up, the ability to get the job done faster and better become more and more important. This is where people turn to machine applied mortars. Here, mortars are applied through a pumping system to lay down a layer onto the surface to be covered. Such systems are now being used for renders, skim coat and EIF mortars.
In spray (machine applied) applications, the mortar must be thixotropic (shear thinning) enough to be pumped out of the nozzle but must also thicken almost instantaneously upon leaving the nozzle to minimise bounce back and form an inter-particle network structure that will not sag. The applied layer must also be easy to work with (workability), have good smoothening properties, and support water retention that is vital for complete hydration of the cement to build strength.
Avebe starch ethers help you formulate a good spray mortar with the key required parameters.
Working outside means extremes of temperature, weather, and the unexpected. The more reliably and effectively Exterior Insulation and Finishing Systems (EIFS) can be completed, the happier your customers (and their own customers) will be. EIFS is a complex system of insulation layers that entraps air or includes insulation materials like Stryrofoam or glass beads. The structure forming properties of starch ethers add to creating a network that improve the EIFS, giving professionals a range of options for getting the best result.
Like other cementious dry mortar additives, Avebe starch ether in your EIFS products leads to less sag and more open time to work with. Valuable when working inside, even more so when working on exteriors. Both base coat and finish coat allow more water in the mix, for easier workability when sealing against weather intrusion and maintaining better adhesion to insulating material. EIFS is among the most important jobs in construction, but it can also be the most resource-intensive. Avebe’s EIFS value-additives let your customers keep every project on track.
Like renders, these are corrective layers applied to wall surfaces to rectify bigger imperfections. They can be applied both manually and via spraying. (machine applied plasters). Appreciated characteristics include ease of application, long working times, low stickiness, and easy smoothening.
All these benefits help improve speed and efficiency of application resulting is cost savings and repeat business by tradesmen. Let us help you select the best products for your needs.
