Bona Extender 200ml – Additive for Bona Waterborne Finishes

Bona Extender 200ml – Additive for Bona Waterborne Finishes

Bona Extender is a professional coating additive designed to improve the application properties of compatible Bona waterborne floor finishes. It extends the open time of the coating, giving the applicator more time to work the product and helping achieve a smooth, even finish under challenging application conditions.

Extended open time can be particularly useful when coating larger floor areas or working in conditions where a waterborne finish may otherwise dry too quickly. Bona Extender helps maintain a workable wet edge, reducing the risk of overlaps and application marks while supporting a more consistent final appearance.

Why Use Bona Extender?

Waterborne floor finishes can dry quickly, particularly across larger areas or when site conditions accelerate evaporation. This can reduce the time available to blend adjacent sections of coating and maintain a continuous wet edge.

Bona Extender increases the available working time of a compatible finish, giving the applicator greater control during application and helping produce a more uniform finished surface.

Application Guidance

Mix Bona Extender thoroughly into a compatible Bona waterborne finish before application. Follow the current Bona Technical Data Sheet for the selected coating to confirm compatibility and the correct amount of Extender to use.

Do not exceed Bona’s specified addition rate. Once mixed, apply the coating using the recommended Bona application method and observe all drying and recoating instructions for the complete finishing system.

Important Note

Bona Extender is a coating additive and must not be applied directly to the floor as a standalone product. Compatibility and dosage depend on the Bona finish being used, so always follow the current technical instructions for the complete coating system.

FAQs

What does Bona Extender do?
It extends the open time of compatible Bona waterborne finishes, providing additional working time during application.

Why is a longer open time useful?
It makes it easier to maintain a wet edge, particularly across larger floor areas, and can help reduce overlaps and application marks.

Can Bona Extender be applied directly to wood?
No. It is an additive that must be mixed into a compatible Bona waterborne finish.

Is Bona Extender useful in warm conditions?
It can be particularly useful when application conditions cause a compatible waterborne finish to dry faster than desired.

How much Bona Extender should I add?
Use only the quantity specified in Bona’s current technical instructions for the particular finish being used. Do not estimate or exceed the recommended dosage.
