PRIMER PR3800

All Purpose Primer


PR3800 Primer is essential for preparing substrates for additional coating performance and to insure best possible results on many substrates. The tough, flexible film adheres tenaciously and is resilient enough to absorb expansion and contraction. This primer will work on metal, wood, concrete, masonry, tile, slate, stucco and asphalt coatings.

APPLICATION PROCEDURES

  • This product can be sprayed, brushed, or rolled on.
  • When using airless spray equipment, it is recommended that a reversible spray tip be used with an orifice of .017 to 0.24 and minimum 40 degree fan angle.
  • Material should be applied to a 4 - 12 mil thickness depending upon porosity of substrate.
  • Mix material if separated.
  • Please consult Coatings International with specific application questions.

PERFORMANCE TIPS

  • DO NOT THIN.
  • POWER MIX BEFORE USING.
  • On porous surfaces allow to cure four hours.
  • All loose rust and scale should be removed.
  • Rusty areas should be saturated without leaving any excess material.
  • Puddles may blister the finish coat if not cured before coating.
  • Can also be applied with a pump sprayer.
  • Non-rusty metals require just a thin coating.
  • Recoat within one hour in good weather. Recoating can proceed with urethanes while surface is still somewhat tacky.
  • PR3800 has no recoat window but dirt that accumulates on the material will have to be removed.
  • Do not allow containers to freeze.

CLEANUP INSTRUCTIONS

  • Clean spills, spatters, and tools immediately with water.

  • Clean hands immediately after use with soap and water.

  • After cleaning, flush spray equipment with water followed by mineral spirits. Leave mineral spirits in the line to prevent rusting.

SAFETY PRECAUTIONS

  • For chemical emergencies, spills, leaks, exposure, or accidents in the U.S.: CALL CHEMTREC 24 HOURS A DAY / 365 DAYS A YEAR 1-800-424-9300.

  • This product is designed for professional use. Caution must be exercised to prevent mishaps due to improper handling.

  • Any installation equipment employed for application should be designed for high pressure use.

  • The use of appropriate MESA/NIOSH approved respirator during application is important. We also recommend the use of fabric coveralls and gloves.

  • INSTALLERS must read and understand all technical and informational literature for Tough Stuff PR3800, including the Material Safety Data Sheets, prior to using this product.

SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE/LEAKS

1) STEPS TO BE TAKEN IF MATERIAL IS SPILLED OR RELEASED:

Keep unnecessary people away. Dike and contain spill with inert material (sand, earth, etc.) and transfer liquid to containers for recovery or disposal. Keep spill out of sewers and bodies of water. Floors may be slippery, care should be exercised to avoid falls.

2) WASTE DISPOSAL METHODS:

Coagulate the emulsion with ferric chloride or sulfate and then lime to a clear end point. Decant the clear liquid to sewer and landfill the coagulum. Incineration of the entire emulsion is possible but impractical because of the high water content. Coagulum may be incinerated.
