There could be several factors contributing to the rough, sandpaper-like finish on the intaglio surface of your cold cure relines. Here are some possible reasons and solutions:
- Mixing ratio: Ensure that you are mixing the Teets brand cold cure powder and Henry Schein brand cold cure liquid in the correct ratio as specified by the manufacturer. Using an incorrect ratio can affect the final texture of the material. Double-check the instructions provided with the products.
- Mixing technique: Pay attention to your mixing technique. If the powder and liquid are not thoroughly mixed or if air bubbles are introduced during the mixing process, it can result in an uneven surface texture. Make sure to mix the materials according to the recommended guidelines, using a consistent and controlled mixing technique.
- Temperature and humidity: Cold cure materials can be sensitive to temperature and humidity. Extreme temperature or high humidity levels in your working environment can affect the curing process and lead to an irregular surface texture. Ensure that the temperature and humidity in your workspace are within the recommended range provided by the manufacturer.
- Setting time: Although you mentioned that you have allowed the reline material to fully set according to the manufacturer's specifications, double-check that you are indeed following the correct setting time. Insufficient setting time may result in an incomplete or uneven curing process, leading to a rough surface texture.
- Contamination: Check for any contamination during the process. Ensure that the working area and tools are clean and free from debris or residues that may affect the quality of the relines. Also, make sure to rinse off any disinfectant thoroughly before pouring the material.
- Material quality: While it's unlikely, there is a possibility that the specific batch of Teets brand cold cure powder or Henry Schein brand cold cure liquid you are using could be defective. Contact the manufacturer or supplier to inquire about any known issues with the specific lot or if they have received similar complaints.
If you have tried all of the above suggestions and are still experiencing the issue, it might be helpful to consult with dental professionals or the technical support teams of the manufacturers involved. They can provide more specific guidance and troubleshoot the problem further.

As a dental professional I dont recommend mixing different brands
Ai's answer:
As a dental professional, you are correct that it is generally recommended to avoid mixing different brands of dental materials unless specifically instructed by the manufacturers. Different brands may have different formulations, setting times, and chemical reactions, which can lead to unpredictable results or compromised material performance.
In your case, since you have already mixed Teets brand cold cure powder with Henry Schein brand cold cure liquid, it is possible that the combination of these two different brands may be contributing to the rough surface texture you are experiencing. The interaction between the powder and liquid components could be causing an undesirable reaction or affecting the material's properties.
To troubleshoot the issue, I would advise using cold cure powder and liquid from the same manufacturer and following their recommended instructions for mixing and setting times. This will ensure that the materials are compatible and designed to work together, reducing the likelihood of any undesirable effects.
If you continue to experience difficulties even with materials from the same brand, I would recommend contacting the manufacturer's technical support for further assistance. They will have the specific knowledge and expertise to help troubleshoot the issue and provide guidance tailored to their product.
