CERAfix 103 must be fully cured before the next coat is applied. Cover surfaces not to be treated (e.g. windows and doors) prior to application. Do not work "wet on wet". Protect from frost. Higher temperatures and low relative humidity accelerate the film formation time; lower temperatures and higher relative humidity extend the film formation time. Recognised technical regulations apply along with current standards and ZDB information leaflets.
When CERAfix 103 is applied as a surface sealing agent to mineral-based materials, surfaces can appear much darker and possibly even different shades. Shading and colour changes do not constitute a defect or affect the strength or benefit of the product. If necessary, test areas must be created in advance and evaluated with the customer.
Cerafix 103 is not suitable for use as a coating. When used for waterproofing or as a primer, it is important to ensure that the product is applied extremely thinly. Otherwise, there is a risk of irregular deposits and uneven surfaces. The surface can also become shiny. When applied on an untreated and porous surface, a colour-enhancing effect (wet effect) can occur, depending on the surface texture and absorbency. This is not considered grounds for a complaint.

The usage instructions are recommendations based on the tests we have conducted and our experience; carry out your own tests before each application. Due to the large number of applications and storage and processing conditions, we do not assume any liability for a specific application result. Insofar as our free customer service provides technical information or acts as an advisory service, no responsibility is assumed by this service except where the advice or information given falls within the scope of our specified, contractually agreed service or the advisor was acting deliberately. We guarantee consistent quality of our products. We reserve the right to make technical changes and further develop products.
Cured product residues can be disposed of according to waste code AVV 15 01 06.
- For priming and sealing pores. Spread plenty of TEGAfix 430 quartz sand over the fresh primer coat.
- For producing levelling fillers and scratch coats and preparing substrates for coatings.
- For joining cracks and joints in screed and concrete.
- For producing epoxy resin screeds and mortar.
- For waterproofing to strengthen substrates.
- For use as a binder for epoxy resin mortars to seal penetrations and fixtures.
For all applications, mix the CERAfix 103 inside the two-chamber pierceable container following the procedure below:
- Wear suitable protective equipment, such as safety goggles/face protection and gloves! The hardener is acidic!
- Component A (resin) and component B (hardener) are supplied in the correct mixing ratio. Add component B (hardener) to component A (resin). To do so, pierce the top chamber of the pierceable packaging with a tool such as point chisel to allow the hardener to flow down into the second chamber. Make sure that there is no hardener remaining in the container.
- Use a suitable Würth agitator to mix the two components at a speed of approx. 250 to 300 rpm, taking care to not add in any air. Stir in any hardener that has adhered to the sides and bottom of the container to ensure that it is distributed evenly. Mix until the mixture is homogeneous and streak free, which should take around 3 minutes. Transfer the mixed product into a clean mixing bucket and stir again thoroughly. Do not apply the material directly from the original container.
