Substrate Best Practices
- Substrates (backgrounds) should be kept dry, prior to applying the render.
- Fastening deflection netting to your scaffold will assist you in protecting your substrate from the winter elements and is always good practice to have during your render project.
- The adhesion and bonding characteristics of the render application onto substrates with high a moisture saturation will become problematic. This may cause a reduced bond for the render, causing weakness, where the lack of suction is dramatically reduced.

Check out some of our K Rend Products we recommend for Winter Working:
Mineral TC: a cement based, polymer modified render, requiring only water to be added and 10 minutes to mix. Mineral TC allows render to dry faster at a lower temperature and high humidity.
Accelerator: a liquid additive used to reduce the waiting time before scraping K Rend scraped texture renders. K Rend Accelerator speeds up the curing time allowing render to be scraped earlier and resulting in a faster job completion.
