Q11: How much water can I use?
A11: Follow the manufacturers' recommendations. Normally 25 to 30 gal. per 100 gal. of concentrated sealer is recommended. Higher percentages are recommended for mix designs that use additives and larger amounts of sand.
Q12: What happens when you use different additives (different suppliers) in the same tank? Why does the viscosity go haywire?
A12: The viscosity went haywire because the additives were not compatible with each other. Do not mix different additives and stick to manufacturer recommendations. Also the manufacturer's warranty may be void if you use other additives.
Q13: Why does sealer fail or peel?
A13: Peeling is caused by sealer not bonding to oil spots or any other surface containments like dirt, grease, etc. or oxidized pavements . All the areas shall be thoroughly cleaned; oil spots must be primed with specialty primers. Oxidized pavements should be treated with a diluted coat of sealer, specialty product, or asphalt emulsion.
