Mineral Stains Warranty
What kind of warranty does Mineral Stains offer?
Mineral Stains offers a 20-year warranty on exterior masonry stain products and a 1-year warranty on labor, provided the installation is completed by our approved installers. Unfortunately, we cannot accept any refunds on custom orders (defined as any non-white color).
**Warranty Conditions**
The warranty is valid only when a certified technician is present during the installation. We cannot assume liability under the following conditions:
- Primer is not applied properly or is omitted.
- Mortar is failing and needs replacement.
- The masonry substrate is non-absorbent.
- The pH moisture level exceeds product specifications.
- Excessive water is present in the masonry (repair recommended before staining).
- Potassium silicate stains have a maximum moisture tolerance of 6%.
- When salt is added in common areas, during winter, The sodium and chloride ions from the dissolved salt can interact with the potassium silicate in the coating, potentially forming sodium silicate and potassium chloride, which may weaken the coating's integrity.
- Cement stains have a maximum moisture tolerance of 15%.
- Stains/paints are diluted beyond the maximum allowable 10% dilution rate for masonry stains.
- The masonry has been treated with acid-based treatments or silicone.
- Accelerators and waterproofing agents have been added to the mortar mix.
- Improper downspout/gutter systems or lack of drip edges may lead to water streaks over time. This is not caused by the failure of our product but rather by inadequate water protection.
Thank you for choosing Mineral Stains.
