DSF's Ultimate Sand Suspension (USS) technology ensures that sand is better suspended within the seal coat, preventing sedimentation at the bottom of tanks. This technology also helps in producing smoother, silkier sealers that are easier to apply and less likely to cause wear on application equipment.

Mixing Procedures

  1. DSF does not require dilution before addition to the mix.

  2. For lower traffic areas, use 1/2 gallon of DSF per 100 gallons of raw sealer.

  3. For higher traffic areas, use 3/4 gallon of DSF per 100 gallons of raw sealer.

  4. For night work, use no more than 1¼ gallons of DSF per 100 gallons of raw sealer.


Apply DSF in appropriate weather conditions, avoiding excessive humidity or ground saturation. Follow all manufacturer guidelines for sealer application. DSF allows for sealer application at night, facilitating flexible scheduling and reducing disruptions.
