Holdout

To seal interior, aged concrete floors that are subject to foot and hand-cart traffic follow these directions.

Preparation: Strip the floor with #1 Remover then pick up spent solution with a mop or wet-vac making sure the solution does not dry. Rinse floor with NEUTRAMAX as per label instructions. Allow the floor to dry for 1 – 2 hours.

Application: Use a clean finish mop, either fine string or candy striped. Pre-wet with water and wring out mop to conserve finish. Apply an even coat of HOLDOUT with a mop. On very porous surfaces a second coat may be applied. Allow 30 – 40 minutes between coats. HOLDOUT can be top coated with any one of Project Clean’s quality floor finishes.

When applying to new concrete (which must be no less than 90 days old) the surface must be acid washed and rinsed well before using HOLDOUT. It covers 1000 to 2000 square feet per gallon 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).
