Directions for Use

Covers 93 to 189 square meters per litre depending on porosity of flooring. It may be removed with a solution of #1 REMOVER at a dilution of 1000 mL per litre of water (128 oz/gallon) (1:1). 

General Application: 

  1. Completely strip old floor finish with a floor finish remover such as FINISH REMOVER or #1 REMOVER.
  2. Remove the stripping solution and rinse floor with a neutral pH cleaner such as NEUTRAPOWER and NEUTRAL CLEAN or follow with two to three clear water rinses. Allow to dry.
  3. Use a clean finish mop, either fine string or candy striped. Pre-wet with water and wring out mop to conserve finish. 
  4. Apply an even coat of HOLDOUT in a uniform and medium coat. Let dry thoroughly – approximately 30-40 minutes between coats. One sealer coat is usually all that is needed before applying a floor finish on top. On older, worn or porous surfaces a second coat may be applied.  HOLDOUT can be top coated with any one of Project Clean’s quality floor finishes.

Application on new concrete (no less than 90 days old): 

  1. Acid wash the surface and rinse thoroughly. 
  2. Apply HOLDOUT as directed above.
