UsageUse with Sikalastic® Traffic Systems as a primer on concrete, cementitious or plywood surfaces exposed to vehicular or pedestrian traffic. Refer to the Sikalastic® 710/715/735 AL Traffic System, Sikalastic® 710/715/736 LoVOC Traffic System and Sikalastic® 720/745 Traffic System Product Data Sheets for system application instructions as well as limitations.
- Low VOC
- Fast dry time
- Low odor
Sikalastic® FTP Primer is packaged in pre-proportioned kits, both diluted with water in the field. 7gal. kit - two 1 gal. cans Part A and two short-filled pails Part B (1.25 gal. each). Kit yields 7 gal. after dilution with 2.5 gal. water (see mixing instructions). 1 gal. kit - short filled can of Part A (0.28 gal.) and a short filled gallon can Part B (0.35 gal.). The kit will yield one gallon of mixed product after dilution with 0.35 gal. water. (see mixing instructions).
2 years in original unopened container under proper storage conditions.
Store dry between 40–90 °F (4–32 °C).
Condition material to 65–85 °F (18–30 °C) before using.
Volatile organic compound (VOC) content
Tensile Adhesion Strength
> 400 psi
(100 % concrete failure)
(ACI 503R, Appendix A)
Approx. 1 hour at 77 °F (25 °C) and 50 % relative humidity
3–4 h at 77 °F (25 °C) and 50 % relative humidity
Waiting / Recoat Times
Up to 48 h at 77 °F (25 °C)
Approximately 300 ft.2/gal.
Porous and rough substrates will increase consumption.
Concrete surface must be clean, sound and dry. Remove dust, laitance, grease, curing compounds, bond inhibiting impregnations, waxes and any other contaminants. All projections, rough spots, etc. should be dressed off to achieve a level surface prior to the application. Concrete should be cleaned and prepared to achieve a laitance and contaminant free, open textured surface by shot blasting to a minimum of (CSP 3-4 as per ICRI guidelines). Sweep and vacuum any remaining dirt and dust with a wet/dry vacuum. Removing residual dust will help ensure a tenacious bond between the primer and substrate. The compressive strength of the concrete substrate should be at least 3500 psi at 28 days and at least 250 psi in tension at the time of application of Sikalastic® FTP Primer.
7 gal. kit: It is important to remember that this coating has a limited pot life of approximately 1 hour at 77 °F (25 °C) and 50 % relative humidity. Do not use beyond this frame regardless of whether or not the product appears to still be usable. Review that all surface preparation is complete and application equipment is in good working order before starting the mixing sequence.
1 gal. kit: It is important to remember that this coating has a limited pot life of approximately 1 hour at 77 °F (25 °C) and 50% relative humidity. Do not use beyond this frame regardless of whether or not the product appears to still be usable. Review that all surface preparation is complete and application equipment is in good working order before starting the mixing sequence.
NOTE: The order that the FTP components are mixed is critical to the performance of this product. Failure to mix properly may result in an incomplete cure, despite a dry appearance.
Apply with flat squeegee or roller at the recommended rate. Allow for sufficient wetting of the slab and backroll, utilizing a ¼” or ⅜” nap roller to eliminate puddles on the surface of the slab. Minimize the overlap from batch to batch or bead-to-bead applications while achieving complete slab coverage, as these areas of overlap may not bond.
Remove wet primer with MEK, xylene, or oxygenated solvents. Once cured, primer can only be removed by mechanical means. Strictly follow solvent manufacturer’s warnings and instructions for use.
Sikalastic® FTP Primer has a recoat window of up to 48 hours. Do not apply a second coat of Sikalastic® FTP Primer, as it will not properly bond. There is no need for additional mechanical or chemical preparation of the Sikalastic® FTP Primer prior to the installation of the topcoat, if recoated with in the recoat window, and the Sikalastic® FTP Primer has not been exposed to foot or vehicular traffic or similar. If the recoat window is missed (48 hours) the surface requires grinding or screening with 80 grit, followed by a broom sweep and vacuum, prior to reapplication of Sikalastic® FTP Primer.
