FOSROC RENDEROC PLUG / WATERPLUG 4.5KG

The material is based on a blend of cement, graded aggregates, special fillers and chemical additives which control the rate of set and minimise the risk of thermal cracking. Renderoc Plug provides an initial set time of approximately one minute.

Renderoc Plug is supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a highly consistent, rapid setting mortar which is easy to apply in many difficult conditions. The material is based on a blend of cements, graded aggregates, special fillers and chemical additives which control the rate of set and minimize the risk of thermal cracking. Renderoc Plug provides an initial set time of approximately one minute.

Instruction for use
Preparation
Areas to be patched should be cut back to a depth of 15 mm and given a good mechanical key. Feather-edges must not be allowed. Surface should be brushed clean to remove loose material, dust and laitance. Grease, slime or mould growth should be removed by steam cleaning or high-pressure water jetting. A proprietary degreasing agent should be used for removal of light oil or grease contamination.
To seal leaks, crack openings must be chased out to approximately 20 mm square. The chase should always be undercut to avoid leaving a v-section. All loose material and debris should be removed.

Mixing
Renderoc Plug should be added to clean water in the following proportions:
One part clean water: 3 parts Renderoc Plug (measured by volume).
Mix to a stiff consistency in a suitable mixing drum or bucket, using a trowel or gloved hand. Due to the rapid set characteristics of the product, only prepare a quantity of mortar which can be placed within the prescribed set time.

Application
Trowel apply or hand-knead the mixed mortar in place, ensuring maximum contact with the substrate before the material sets. If being used to plug running water, Renderoc
Plug should be used and held in place until the initial set is reached. Note the minimum applied thickness of Renderoc Plug should be 15 mm.

Features:

• Emergency water-stopping capability.
• Single component – only the addition of clean water is required.
• Excellent bond to the substrate.
• Low exotherm minimises thermal cracking.
• Pre-bagged formulation to overcome variations in site batching.
• Contains no chloride admixture

Application Instruction:

• Cut open all cracks or hole to be treated to a minimum depth of 25mm
• Throughly clean the areas to be treated
• Mix Renderoc Plug with clean water 
• Wet the area to be treated with water prior to apply Renderoc Plug
• Force Renderoc Plug into hole or crack by pushing firmly
• Keep the treated area damp to ensure proper curing

Cautions/Hazard:

• Wear protective gloves
