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). This primer is ideal for render, smoothing and levelling compounds and cementitious adhesives, for internal and external application on both walls and floors.
Eco Prim Grip Plus is suitable for improving the bond of adhesives for smoothing ceramics and levelling compounds on non-absorbent surfaces, such as ceramic, terrazzo and natural stone floors and smooth surfaces like for example epoxy or polyurethane resins. Eco Prim Grip Plus may be also used to improve the bond of cement and lime-based plasters on substrates made from concrete, brickwork, vibro-compressed concrete blocks.
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 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.
Eco Prim Grip Plus is a ready-to-use grey latex which is easy to apply using either a roller or a brush. Eco Prim Grip Plus is non-flammable and has an extremely low emission level of volatile organic compounds (VOC). It may also be stored without taking particular precautions.
Features & Benefits of Mapei Eco Prim Grip Plus Primer
Preparing 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 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 suitable products.
There is no need to wet the surface before applying Eco Prim Grip Plus.
Application
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 Eco Prim Grip Plus from the application of the first coat after a long time. If used as adhesion promoter for cementitious smoothing compounds on substrates treated with epoxy or polyurethane primers without broadcasting of quartz sand, Eco Prim Grip Plus must be applied neat after complete drying and after max. 24 hours from the application of said primers. This type of application is possible in case of skimcoats of max. 10 mm and only if no application of hardwood is planned.
