Application of SpECbuild Primer E1
Proper application is essential to achieve the desired bonding performance of SpECbuild Primer E1. The following steps outline the preparation and application process:
Preparation:Before applying SpECbuild Primer E1, ensure that the prepared surface is free from laitance, dust, algae, oil, and grease. Adequate preparation is crucial for a successful bond.
Mixing:SpECbuild Primer E1 is supplied in a two-component kit, consisting of a base component and a curing agent. Both components must be briefly stirred to ensure any settled products are fully suspended. The entire contents of the curing agent should then be emptied into the base component, ensuring that the sides of the curing agent tin are scraped to remove all material. Combine the materials using a suitable slow-speed drill and mixing paddle for a minimum of 2 minutes until uniform, scraping the sides of the container and mixing for an additional 2 minutes.
Application:The mixed product may be applied by brush or suitable applicator. It is recommended that a theoretical consumption rate of 5 m²/litre is expected. Where SpECbuild Primer E1 is used as part of the SpECbuild concrete repair system, care should be taken to ensure an unbroken coating. One coat should be applied and allowed to gel before applying a second coat, which will provide the necessary bond. In applications where a subsequent repair product is to be sprayed, sharp sand may be broadcast onto the surface of the second coat of the primer.
Application Temperature Range:For optimal performance, SpECbuild Primer E1 should be applied within the following temperature ranges:
To improve mixing and application characteristics, it is advised to store the material in an environment above 5°C if the ambient temperature is lower. If temperatures exceed 35°C, the pot life will be reduced; thus, storing the material in a cool environment is recommended.
SpECbuild Primer E1 is available in various packaging options to suit your project needs:
The theoretical consumption rate is 5 m²/litre.
