Please see preferred Master Seal Deck Coating Solution for total system and aggregate surface preparation and application. MasterSeal225 Tint Base is intended for pedestrian use only and is not suitable for vehicular traffic.
MasterSeal TC225 Tint base should be mixed with two (2) BASF MasterSeal 900 color packs per 5 gallons in order to achieve the desired color tint. When installing MasterSeal TC225 Tint Base, a second coat may be required for proper hiding.

  •  Avoid whipping air into Tint Base.
  • Mix pigment cans thoroughly into Tint Base.
  • Always do a test area to assure acceptable color appearance and slip resistance.
  • Do not apply MasterSeal TC 225 Tint Base heavier than the recommended 15−20 mil (0.38−0.51 mm) application.
  • Colors exposed to direct sunlight may fade over a period of time. Darker colors potentially fade at an increased rate.
  • Aggregate and substrate conditions may affect color and appearance.

MasterSeal TC 225 is an aliphatic, moisture-curing polyurethane available in grey, charcoal, tan, dark tan and tint base. MasterSeal TC225 cures in 12−14 hours when tested at 73 °F (23 °C) and 50% relative humidity.

Concrete must be fully cured (28 days), structurally sound, clean and dry (ASTM D 4263). All concrete surfaces (new and old) must be shot blasted to remove previous coatings, laitance and all miscellaneous surface contamination and to provide profile for proper adhesion. Abrasive shot blasting must occur after concrete repair has taken place. Acidetching is not permitted. Proper profile should be a minimum of ICRI CSP-3 (as described in ICRI document 03732.) For balconies and other pedestrian areas with limited space or access for shot-blasting, alternative mechanical methods can be used to achieve the recommended surface profile
