Description
VURA MaStik
Single component, fibre-reinforced cementitious mortar for waterproofing and concrete protection. It has very high water permeability against hydrostatic pressure with standing capacity. It is to be mixed with water and applied by brush or trowel.
CHARACTERISTICS
– Waterproof
– Water permeable
– Suitable for drinking water tanks
– Strong reduction of capillary absorption of water increases surface protection
– Frost resistant
– Economical application
– Can be applied by brush, trowel
– Excellent adhesion to cement surfaces
– Resistant to negative water pressure protects standard concrete structures

Usage Guide
SUBSTRATE PREPARATION
The mineral substrate must be even, solid, load-bearing, clean, crack-free and free of substances that may impair adhesion. The surface must have a rough, open pored structure with good grip. The surface should be clean and free from dirt, oil or grease before application.
Cove all corners with a moulding of at least 2 cm radius. Repair any defects, screed over rock pockets and fill mortar joints, with Vura mortar products. Enlarge the cracks and fill them with polymerized cement mortar alternatively with epoxy resin. If the brickwork is uneven with numerous projections and defects, produce a levelling render made of cement mortar. Vura MaStik requires pre-wetting of the substrate before application, avoiding formation of puddles. When waterproofing wall and foundation areas indoors or outdoors, e. g. in the case of rear penetration of moisture, pre-treat the areas with Vura products.
When waterproofing from negative side, the substrate must have sufficient mechanical strength.
APPLICATION
VURA MaStik is prepared with clean and clear water @ 30-32% water ratio and is mixed until it becomes homogenous and free of lumps. The consistency of the mortar should be adjusted according to the application.
The quantity obtained must be applied within 1 hour. The first layer will be applied consistently with a brush or trowel on the wetted surface. When successive layers are applied, the next layer must only be applied when the previous layer is hardened, Interval time between two coat is apprx. 4-5 hrs. Work must not be interrupted for more than 12 hours.
Do not apply the VURA MaStik to a substrate that shows the signs of standing water on the surface. Apply second coat after First coat is dry to touch, perpendicular to the direction of the first coat. The Wet Film thickness per coat should be between 0.8 mm to 1.00 mm
The freshly applied product must be protected against drying too fast.
The coating can be walked on after two days; however, even after complete hardening, the coating must not be directly exposed to heavy mechanical loads.
Keep the freshly applied coating in the wet conditions for at least 3 days. Protect VURA MaStik against rain for at least 24 hours. Tiles, plasters or flooring can be applied on a layer of VURA MaStik after 7 days at the earliest from drying out too quickly, frost and precipitation. Installation of covers protecting from direct sunlight, draughts, rain and frost is recommended.
