| Mixing Ratio | A:B = 1:1 (by volume) |
| Product Temperature | Condition product at temperatures between 18 and 24 °C (65 and 75 °F) before and during application. Note: 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. |
| Ambient Air Temperature | Minimum: 10 °C (50 °F) / Maximum: 30 °C (86 °F) Note: Mixing carried out under conditions where the Sikafloor® Vertical Epoxy Primer temperature and ambient temperature are below 18°C (65°F) will result in reduced product workability and slower curing rates. |
| Relative Air Humidity | Maximum 85 % (during application and curing). |
| Dew Point | 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. Be aware that the substrate temperature may be lower than the ambient temperature. |
| Substrate Temperature | Minimum: 10 °C (50 °F) / Maximum: 30 °C (86 °F) Note: Any attempt to apply Sikafloor® Vertical Epoxy Primer at substrate temperature conditions less than 18 °C (65 °F) will result in an increase in viscosity and slower cure rates. |
| Substrate Moisture Content | 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. |

| Curing Time | Ambient & Substrate Temperature Open Time Foot Traffic 20 °C (68 °F) ~1 hour (at 10 mil w.f.t) ~12 hours Note: Curing times will vary according to ambient air and substrate temperatures and relative humidity. Freshly applied material should be protected from dampness, condensation, and water for at least 72 hours following the end of the application. |

| Consumption | 4-5 m 2 /L (160-200 ft 2 /US gal) at 8-10 mil w.f.t. Note: Actual coverage rates and material consumption will depend upon porosity and profile of substrates. Test sections are recommended to establish correct coverage. |
| APPLICATION | Apply by brush or roller to the required thickness over a properly prepared substrate. Apply the Sika® Ucrete® mortar or the Sikafloor® 293 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 UP | Clean all tools and equipment with a non-flammable solvent. Once hardened, product can only be removed mechanically. |
| Cure time | Ambient & Substrate Open Time Foot Traffic Temperature 20 °C (68 °F) ~1 hour (at 10 mil w.f.t) ~12 hours |

Full product details, applications & manufacturer specifications
Sikafloor® Vertical Epoxy Primer is a 100 % solids, two-component, moisture tolerant, epoxy adhesive used as a primer for Sikafloor®-293 cove and detailing mortar.
Recommended uses
Sikafloor® Vertical Epoxy Primer is used as a tacky primer and adhesion promoter for the vertical application of Sikafloor® mortars. Primer for concrete substrates and most steel surfaces that have been properly prepared.
Floors- Coverage
4-5 m 2 /L (160-200 ft 2 /US gal) at 8-10 mil w.f.t. Note: Actual coverage rates and material consumption will depend upon porosity and profile of substrates. Test sections are recommended to establish correct coverage.
- Application method
Apply by brush or roller to the required thickness over a properly prepared substrate. Apply the Sika® Ucrete® mortar or the Sikafloor® 293 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.
- Drying time
Curing Time: Ambient & Substrate Temperature Open Time Foot Traffic 20 °C (68 °F) ~1 hour (at 10 mil w.f.t) ~12 hours Note: Curing times will vary according to ambient air and substrate temperatures and relative humidity. Freshly applied material should be protected from dampness, condensation, and water for at least 72 hours following the end of the application.
Use the sheet for your exact product code and finish. Coverage and times depend on the stated temperature, humidity, substrate and coat thickness.
