Primers Pedestrian Traffic Coatings - Sikalastic® FTP Lo-VOC Primer

TWO-COMPONENT HIGH SOLIDS EPOXY PRIMER

Sikalastic® FTP Lo-VOC Primer is a two-component, high solids epoxy primer for use with Sikalastic traffic deck coatings.

• Low VOC
• Fast dry time
• Low odor
• Moisture tolerant

Usage

Use with Sikalastic® Traffic Systems as a primer on concrete, cementitious or plywood surfaces exposed to vehicular or pedestrian traffic. Refer to the Sikalastic^® 710 Lo-VOC/715 Lo-VOC/736 AL Lo-VOC, the Sikalastic^® 710/715/735 AL, & the Sikalastic^® 720/745 Traffic System Data Sheets or Sikalastic^®-720 One Shot & Sikalastic^®-726 Balcony One Shot product data sheets for system application instructions as well as limitations. Can be used as a recoat primer over existing PU coatings. Adhesion test is recommended.

Application Steps

SUBSTRATE PREPARATION

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 blast cleaning or equivalent mechanical means (CSP-3-4 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 Lo-VOC Primer.
Plywood - Should be clean and smooth, APA and exterior grade, not less than 1/2” thick, and spaced and supported according to APA guidelines. Joints should be sealed with Sikaflex® 2c or 1a and detailed, and may need embedded fabric reinforcement.

Exisiting PU Coating - Existing coating surface must be clean, dry and sound with an open texture. Remove dust, grease, waxes, and any other contaminants. All loose and flaking coating, projections, rough spots, etc. should be dressed off to achieve a well-bonded, level surface prior to the application. Mechanically abrade the existing coating as required to obtain an open, textured surface profile.

MIXING

Premix Part A (blue liquid) and Part B (yellow liquid) components separately using a low speed (400-600 rpm) mechanical mixer and Jiffy Paddle at slow speed to obtain uniform color (typically 30 seconds), making sure to scrape the solids from the bottom and sides of the pail. For the 3 gallon kit, pour Part B into Part A slowly and while mixing scrape the side of the container, For the 15 gallon kit, pour Part A into a separate mixing vessel and then pour part B into Part A. Mixing ratio is 2 parts A to 1 part B. Mix the combined material thoroughly until a homogenous mixture and uniform color is obtained (typically 3 minutes). Use care not to allow the entrapment of air into the mixture. Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.

APPLICATION

Apply with flat squeegee or phenolic resin core 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. Allow to become tack-free before overcoating, typically 6-8 hours at 75 °F (24 °C) and 50 % R.H. Sikalastic® FTP Lo-VOC Primer must be overcoated within 24 hours.

Removal

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.
