Batimix Plaster 270

Description

BATIMIX Plaster 270 is a pre-packaged cementitious-based mortar used for carrying out traditional plastering works. It is a blend of a hydraulic binder, carefully graded sand, and selected additives, such as plasticizing, air-entraining, and shrinkage-compensating agents.

Main Purpose

BATIMIX Plaster 270 is used for plastering interior and exterior masonry elements. It is recommended for use on concrete and brick block walls, partitions, and ceilings. It forms an ideal substrate for paint, wallpaper, and decorative plasters. It is also used for general filling-up works. It is applied with a suitable plastering machine or by hand onto prepared concrete surfaces and blockwork. It allows for the fast completion of plastering works.

Features

BATIMIX Plaster 270 exhibits the following characteristics:

• Spreads and clings easily on cementitious-based substrates
• High degree of bond because of the intimate contact of mortar/substrate
• High-performance strength and flexural characteristics
• Lower level of shrinkage (because of the shrinkage- compensating agent)
• Better durability and surface quality

Health and Safety

BATIMIX Plaster 270 contains cement and thus is irritating to the eyes and skin. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Wear suitable gloves. For further information, kindly refer to the Material Safety Data Sheet.

Directions for Use

Substrate preparation: BATIMIX Plaster 270 must be applied on sound and thoroughly cleaned substrates free of oil, dust, loose particles, and paints. The traces of mould joints must be leveled. In order to increase friction of smooth surfaces, a spatter-dash slurry coat such as the BATIMIX Key Coat 240 or 250 should be applied on the substrate.

Product preparation: Depending on the required consistency, a 50-kg bag of BATIMIX Plaster 270 is mixed manually or mechanically with 7.5 to 9.5 liters of clean water until a homogenous mix is obtained.

Application: BATIMIX Plaster 270 can be applied either manually with a plastering trowel or with a mechanical projection machine in layers not exceeding 15 mm. In case multiple layers are required, it is recommended that the subsequent layers be applied at least 24 hours from the first application. For detailed application instructions, kindly refer to the product’s “Application Guidelines”.

Protection and curing: The temperature during application should be between 5 and 35 °C. When finishing, the plaster should be protected from extreme temperatures, wind, and sunshine by moist curing for a minimum of 3 days. Curing compounds can be purchased separately from Holderchem S.A.L.
