Application

Surface Preparation

  • Cleaning the Surface:Ensure surfaces are clean, dry, and free from oil, grease, dirt, laitance, curing compounds, and other foreign materials. Achieve optimal adhesion by creating a roughened, open profile through shotblasting or mechanical abrasion. Vacuum thoroughly to remove dust and debris.

Mixing and Application

  • Mixing SpecPoxy Binder:Do not thin with solvents. Ensure air, material, and surface temperatures are at least 40°F. Precondition materials to 75°F for easier mixing. Mix 1 part of Part A with 1 part of Part B using a low-speed drill and Jiffy mixer for three minutes.
  • Epoxy Mortar Preparation:Gradually add 3.5 to 5 parts of clean, dry silica sand to 1 part of mixed SpecPoxy Binder, ensuring the sand is fully wetted by the epoxy. Apply a neat coat of SpecPoxy Binder as a primer to the prepared substrate, then trowel or screed the epoxy mortar while the primer is tacky.
  • Broadcast Overlays:Apply neat SpecPoxy Binder with a 3/16” notched squeegee at approximately 75-100 sq ft per gallon. Broadcast clean, dry aggregate over the binder after it has leveled out, then remove excess aggregate after curing.

Packaging

Available in 1 gallon units, 2 gallon units, and 10 gallon units.
