2 years in original unopened packaging.

Store dry between 10 and 25 °C (50 and 77 °F).

~ 1.03 kg/L (8.6 lb/US gal.)

< 20 g/L

A:B = 1:1 by volume 

Condition product at temperatures between 18 and 24 °C (65 and 75 °F) before using.

Min. 5 °C (41 °F)   Max. 30 °C (86 °F) 

Mixing and application attempted at material, ambient and /or substrate temperature conditions less than 18 °C (65 °F) will result in a decrease in product workability and slower cure rates.

Maximum 85 % (during application and curing).

Substrate must be at least 3 °C (5 °F) above the Dew Point to reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the floor finish.

Moisture content of a concrete substrate must be < 6 % (pbw -part by weight) as measured with a Tramex® CME/CM Expert type concrete moisture meter.

~ 1 hour at 20 °C (68 °F) at 10 mil w.f.t. (open time on substrate)

~ 12 hours at 20 °C (68 °F) at 10 mil w.f.t. (foot traffic)

~ 5 days at 20 °C (68 °F) (full cure / chemical exposure)

4-5 m²/L (160-200 ft²/US gal.) at 8-10 mil wet film thickness (w.f.t.)

Coverage will vary depending on the porosity of the prepared substrate.

For part unit mixing, i.e. when not mixing full units, each component must be pre-agitated separately to ensure product uniformity. Do not allow mixed material to stand and settle. Failure to pre-stir and keep product agitated will result in variation in gloss levels appearance and performance.  

Do not hand mix Sikafloor^® materials. Mechanically mix only.  Do not thin this product. Addition of thinners (e.g. water, solvent, etc.) will slow cure and reduce ultimate properties of this product.  Mix only that quanity which can be used within its pot life at the actual field temperature.

Pre-stir Components A and B separately, making sure all solids, are evenly distributed and uniform consistencies are achieved within each individual Component. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin) or empty Component A into a suitably sized and clean pail and add Component B in the correct ratio.

Blend the combined components thoroughly at low speed (300 - 450 rpm) for at least three (3) minutes using a drill fitted with an Exomixer® or Jiffy type paddle suited to the dimensions of the mixing container and keep the mixing paddle in the mix to minimize entrapped air. Take care not to introduce any air bubbles while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating.  During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing. When completely mixed, Sikafloor® Vertical Epoxy Primer should be uniform in appearance and consistency.

Apply by brush or roller to the required thickness over a properly prepared substrate. Apply the Sikafloor® PurCem® mortar or the Sikafloor® Epoxy Cove Mortar while the Sikafloor® Vertical Epoxy Primer is tacky, working “wet on wet”. If primer becomes glossy and loses tackiness, remove surface contaminants then recoat with additional Sikafloor® Vertical Epoxy Primer and proceed. 

Clean all tools and equipment with Sika® Epoxy Cleaner. Once hardened, product can only be removed mechanically.
