Description
Mapei Eco Prim Grip Plus Primer is a multi-purpose, ready-to-use, low odour, bonding promoter primer with a very low emission of volatile organic compounds (VOC) for render, smoothing and levelling compounds and cementitious adhesives, for internal and external applications.
Mapei Eco Prim Grip Plus Primer may be used to improve the bond of cement and lime-based plasters on substrates made from concrete, brickwork, vibro-compressed concrete blocks. It is also suitable for improving the bond of adhesives for ceramics, smoothing and levelling compounds on non-absorbent surfaces, such as ceramic, terrazzo and natural stone floors.
Some application examples:
- Application of render on concrete, brickwork, substrates, etc.
- Application of smoothing and levelling compounds on old ceramic, terrazzo and natural stone floors.
- Laying ceramic and natural stone floors directly on top of old ceramic floors.
Technical Characteristics:
Mapei Eco Prim Grip Plus is a low odour, solvent-free primer composed of synthetic resin in water dispersion and aggregates with excellent bond strength, resistance to water and ageing. It guarantees a rough keying surface ideal for render, smoothing and levelling compounds and cementitious adhesives, thus ensuring an excellent bond on smooth substrates and substrates with low absorbency.
Once dry, it guarantees a tough bond of any render, smoothing and levelling compound and cementitious adhesive on various types of substrate: concrete, bricks, stone, plasterboard, wood, ceramic, metal, render, etc.
Mapei Eco Prim Grip Plus is a ready-to-use grey latex which is easy to apply using either a roller or a brush. It is non-flammable and has an extremely low emission level of volatile organic compounds (VOC). Therefore, the product is considered non-hazardous for those who use the product and final users of the environments where it is applied. It may also be stored without taking particular precautions.
Recommendations:
- Apply at temperatures between +5°C and +35°C.
- Do not use Eco Prim Grip Plus in the presence of rising damp or rising humidity, and on continuously immersed surfaces.
- Eco Prim Grip Plus is ready-to-use, no dilution is required.
- Do not use as adhesion promoter for levelling compounds and cementitious adhesives on screeds and power-trowelled concrete. In such cases use Mapei Eco Prim T Plus.
Application Procedure:
Preparation of the substrate: Substrates must be clean, dry, well-cured and free from oil, grease, cement laitance and loose parts.
In case of existing flooring, before applying Mapei Eco Prim Grip Plus, make sure they are well bonded to the substrate and that there are no cracks. Remove any traces of oil, wax, dust, etc. with a suitable product or by abrading the surface with a power tool. If necessary, remove all detached areas and fill the gaps with Planitop Fast 330.
There is no need to wet the surface before applying Mapei Eco Prim Grip Plus.
Application: Mapei Eco Prim Grip Plus may be applied to the substrate by brush or roller. The render, smoothing and levelling compound or cementitious adhesive may be applied once Eco Prim Grip Plus is dry. The minimum waiting time is from 15 to 60 minutes and may vary according to the surrounding temperature and humidity and the absorption of the substrate. It’s possible to apply a second coat of Mapei Eco Prim Grip Plus from the application of the first coat after a long time.
Cleaning: While still fresh, Mapei Eco Prim Grip Plus may be removed easily from floors, walls and tools with water. Once dry, it must be removed with alcohol or Pulicol 2000.
Consumption:
Consumption varies between 0.20 and 0.30 kg/m² according to the absorption of the substrate.
