Application Instructions

Surface Preparation:

Natural wood floors:

  • Sand to 100-120 grit using NWFA approved methods
  • Screen with a 100-120 grit screen.
  • Remove all sanding dust from the floor by thoroughly vacuuming and tack with a Glitsa Tack Mop.
  • At this time a first coat may be applied.

Stained floors:

  • Sand to 100-120 grit using NWFA approved methods.
  • Screen with a 100-120 grit screen.
  • Remove all sanding dust from the floor by thoroughly vacuuming and tacking with a dry Glitsa Tack Mop.
  • Refer to directions on Glitsa Gold Seal Stains for application procedures and dry times.
  • After stains are thoroughly dry, apply seal coat.

Note: It is the contractor’s responsibility to ensure the stain is thoroughly dry prior to coating with waterborne finishes.

Due to seasonal expansion and contraction of wood floors, white lines may appear over dark-stained floors.


Application Instructions:

For best results apply Glitsa TruSeal at temperatures between 60º – 70º F. (15.6º – 21.1º C.), and 30%-70% relative humidity. Additional ventilation and extended dry times may be needed in high humidity or low temperatures. In arid or high temperature areas, 4-6 oz. of water per gallon can be mixed in to retard drying time if necessary. Make sure to have adequate, indirect ventilation while applying TruSeal. Always strain waterborne products that have been stored in partially full containers.

Gently rock container, taking care not to shake vigorously to avoid creating excess bubbles or foam. Let container sit for 5 – 10 minutes to allow any bubbles or foam generated to dissipate before coating.


For best results, apply Glitsa TruSeal using a lightweight T-bar at a coverage rate of 400 – 600 sq. ft. per gallon. Make sure to use a new, lightly water-dampened applicator. TruSeal can also be applied with a 10” pad, nylon brush or a roller.


Start by pouring a 3”-5” puddle of TruSeal with the grain of the wood, from wall-to-wall. Using the snowplow method, pull TruSeal with the grain of the wood, from wall-to-wall. Use a cut-in pad or a T-bar to feather out turns. Maintain a 3” – 5” puddle at all times, as this will help to ensure even coverage, and a uniform final appearance.


When TruSeal has dried to the touch, ventilate premises, while maintaining temperatures of 60º – 70º F. (15.6º – 21.1º C.). Optimum air quality is achieved through aggressive ventilation.


Once dry, abrade with a conditioning pad and (2) 240 grit sanding strips. Do not screen. If sealer is applied over stain, take care not to abrade through to the stain.


A Glitsa waterborne finish may be applied without intercoat abrasion over Glitsa TruSeal after a 2 – 4 hour dry time. Abrading is necessary after 6 hours of dry time. Vacuum thoroughly and tack the floor with a clean, water-dampened, Glitsa Tack Mop.


A first coat of any Glitsa waterborne finish may now be applied. Follow directions on finish label.


NOTE: Apply no more than two coats in a 24-hour period.
