Masking Liquid H2O FAQ’s
Masking Liquid H2O is an acrylic modified water-based clear coating. Formulated to peel from glass, Masking Liquid H2O may be used for interior or exterior purposes.
Masking Liquid H20 can be used on standard tempered glass. Do not use on stained, frosted, coated, etched, tinted or textured glass, as well as plastic glass or Plexiglas.
Masking Liquid H2O is a good primer for bare wood, de-glossed painted surfaces, dull primed metal and finished aluminum. Masking Liquid H2O will adhere to vinyl surfaces, so be sure it is used as a primer only.
All latex, acrylic, vinyl acrylic and alkyd coatings are acceptable finish coats.
- Dry Times: The drying time of Masking Liquid H20 is important!
- Water-based finish coats: Allow Masking Liquid H2O to dry for 4 hours before top coating.
- Alkyd and Water Reducible Coatings: Allow Masking Liquid H2O to dry overnight before top coating.
- DO NOT use lacquers or any coating containing strong solvents such as alcohols or ketones over Masking Liquid H2O.
No, Masking Liquid H2O will seal the wood and not allow penetration of the stain.
Masking Liquid H20 is formulated to peel readily from glass surfaces. (It will also peel from glossy, non-porous surfaces.) Masking Liquid H2O will adhere to bare wood, de-glossed painted surfaces, dull porous aluminum and primed metal (dull sheen). Masking Liquid H2O will bond to vinyl, so use as a primer.
Surfaces must be clean, dry and free of any foreign material. Glossy surfaces must be dulled by sanding. Surface temperatures should be above 50° F. In extremely cold areas, the glass temperature may be much colder than the room temperature.
Masking Liquid H2O can be applied by brush (quality nylon), roller (quality lambskin with a 1” nap) or spray (airless or HVLP). It is best to apply a full coat that will dry down to 3 mils dry.
SPRAY: For best results when spraying, thin Masking Liquid H2O with 1 pint of clean water per gallon and mix thoroughly. Using a 417 tip, spray a test area, adjusting pressure and volume until proper atomization is achieved.
Masking Liquid H2O will dry in 45-60 minutes. However, allow 4 hours dry time before applying water-based finish coats and overnight dry before applying alkyd-based finish coats. Temperature and humidity will affect dry time of the Masking Liquid H2O.
Masking Liquid H2O should be removed within 30 days. In areas with prolonged sunlight and low (dry) humidity, the Masking Liquid H2O should be removed sooner. Changes in temperature, i.e. 20°-40° drop in overnight temperature, will influence the peelability of the Masking Liquid H2O.
The best way is to start in a corner using a dull knife (glass scores easily, so be careful) and work around the glass edges. Carefully peel away the masking liquid. If Masking Liquid H2O is difficult to remove, wet the surface with warm water on a sponge or cloth. In colder temperatures it may be necessary to use a hot air blower to remove Masking Liquid H2O from cold windows.
