Mixing Chart shows amount of Sikalastic® 918 FS (in volume ounces) added to one (1) US gallon of Sikalastic® P 281 FS mixed 3:1 with Sikalastic®-908 FS. Sikalastic® 918 FS is the catalyst for Sikalastic® P 281 FS at all temperatures

Required amount of Sikalastic®-918 FS (in grams) for one (1) litre of resin, based on temperature:

All coverage rates are approximate. Coverage rates will vary with the profile/porosity of substrate. Typically, one (1) US gallon of Sikalastic® P 281 FS will achieve a coverage rate of 9.3 m² (100 ft²), at 16 mil per gallon (minimum).

Concrete
Concrete must be fully cured (28 days), structurally sound, clean, and dry (ASTM D4263). All concrete surfaces (new and old) must be shot blasted to remove previous coatings, laitance, and all miscellaneous surface contamination and to provide a profile for proper adhesion. Abrasive shot blasting must occur after concrete repair has taken place. Acid-etching is not permitted. The proper profile should be a minimum of ICRI–CSP3 (as described in ICRI document 310.2R - 2013.) For balconies and other pedestrian areas with limited space or access to shot-blasting, alternative mechanical methods can be used to achieve the recommended surface profile.

Repair voids and delaminated areas with SikaEmaco®-6000. When time permits, SikaEmaco®-1060 or SikaEmaco®-1060 EX may be used for repair purposes. Wait 24 hours before applying the Sikalastic® Vehicular Traffic 2900 system. Prime with Sikalastic® P 281 FS before applying SikaEmaco®-6000.  Measure three (3) quarts of resin and one (1) quart of Sikalastic®-908 FS into the pail and add the proper amount of powder hardener. See the mixing chart below. Mix with a drill mixer for 45 seconds or until the powder hardener is completely dissolved.Apply primer at approximately 100 ft² (9.3 m²) per mixed gallon.

Add three (3) quarts of Sikalastic® P 281 FS and one (1) quart of Sikalatic®-908 FS into pail. Blend for about 30 seconds. Add the appropiate amount of Sikalastic®-918 FS powder hardener to the liquids based on temperature. Mix for 45 seconds or until the Sikalastic®-918 FS is completely dissolved.

Refer to Mixing Ratio chart for the required amount of Sikalastic®-918 FS (in volume ounces or grams) for one (1) gallon or one (1) liter of mixed resin, based on temperature.

Apply the properly mixed primer to the properly prepared substrate at a rate of approximately 100 ft² (9.3 m²)/US gal or 16 mil thickness. Allow the primer to cure tack-free for an even, satin like matte finish. Re-prime any dry spots. 

Sikalastic® P 281 FS fully cures within one (1) hour when properly installed.

Clean tools with Sikafloor®-100 CLN Pronto, an MMA solvent. Other solvents such as xylene or acetone may also be used.
