Fosroc Renderoc Plug - Instant Leak Plugging Cement 5Kg

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 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.

Advantages

•     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

Renderoc Plug can be applied to horizontal, vertical or overhead surface at a wide range of thickness. Generally, the volume of mixed material used in a single application is restricted to that which can be applied by trowel or gloved hand. Thicker sections can be built up in layers.

Application instructions

Preparation
Areas to be patched should be cut back to a depth of 15mm 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 20mm. 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 container 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.

Cleaning
Renderoc Plug should be removed from tools, equipment and mixers with clean water prior to the initial set. Cured material can only be removed mechanically.

Limitations
Renderoc Plug should not be used when the temperature is below 100C and falling.

Storage Shelf life
Renderoc plug has a shelf life of 6 months if kept in a dry store in the original, unopened bags.
