Implarest® EPW
Two-component water-based epoxy primer/ bonding bridge for preparing damp and dry surfaces.
Additional information
Technical Caracteristics
Product based on epoxy resin and a polyamine hardener.
Advantages and Uses
- Specially designed to increase adherence and improve the flatness of the substrates where MORCEM® ELASTIC PM and MORCEM® ELASTIC POLIUREA, a single-component polyurethane membrane, are to be applied.
- For application on non-porous substrates such as ceramics, metals, wood, asphalt, PVC or asphalt sheets.
- It can also be applied on porous substrates such as concrete or mortar. It is a mixture of two water-based epoxy products. It requires a smooth, clean, dry and as hard as possible substrate.
- It is CE marked as it used under the MORCEM® COVER waterproofing systems, polyurethane membrane and polyurea membrane, under the ETAG 005 guide.
NOTE: consult our technical department for application on other types of substrates or situations.
Suitable Substrates
- Applicable on non-porous substrates: ceramics, metals (pre-painted steel, zinc, copper, galvanised steel...), PVC or asphalt sheets. It can also be applied on porous substrates. It can be diluted with water (maximum 20 %) to facilitate its spreading on the substrate, taking into account the water that may already exist on the substrate.
- Its use as a primer depends on the situation of the substrate, irregularities or flatness level, it may vary between 100-300 g/m² in several coats.
- It can be applied by roller, brush or airless spraying equipment.
- It can be applied on substrates with an existing substrate humidity of max. 10 %.
- Do not apply on substrates with humidity or existing water coming from the inside of the substrate (water pressure due to water table, filtrations...).
- It can be applied in combination with mineral fillers (silica aggregate) on very irregular substrates.
Application Procedure
- The surface must be clean and dry. If necessary, use pressurised water to remove oil, grease, efflorescence and other contaminants, as well as poorly adhered cement slurry.
- In some cases, it is necessary to use mechanical procedures for this specific preparation of the substrate, as well as chemical procedures for cleaning metal surfaces.
- Dilute component A with water (max. 20%), in case of non-porous substrates to apply a thin film, or to facilitate spreading in case of rough substrates.
- Mix both components by mechanical stirring for about 2-3 minutes.
- In any case, check the homogeneity of the mixture.
- Take this residual cleaning moisture into account when carrying out the application, i.e., wait until it has evaporated completely or use measuring equipment to assess its presence in the substrate.
- Apply IMPLAREST EPW in two or more coats until the desired flatness is achieved.
- If the substrate is very uneven, a first coat of IMPLAREST EPW mixed with mineral fillers can be applied to even it out.
- Wait until its drying time has elapsed before continuing with the application of the waterproofing, or re-application of the same product.
Recommendations
- Do not mix at temperatures below + 8ºC and not above +35ºC.
- Epoxy-based product that may irritate the skin, so it is recommended to use it always with gloves, safety goggles and safety overalls.
- Tools and implements shall be cleaned with solvent immediately after use to avoid hardening of the material, which will have to be removed mechanically.
- Mix well before use.
- Consult the Technical Department for any application not specified in this Technical Data Sheet.
- For all information regarding the safe handling, transport, storage and use of the product, refer to the label and the current version of the Material Safety Data Sheet.
