durarep 60 & 180

The substrate must be sound, firm, clean and free of oil, grease, loose particles, cement laitance, old layers of paint or other contaminants. In severe cases chemical or steam degreasing and high-pressure water blasting might be required. Assess the initial adhesion or the effectiveness of the degreasing by means of pull-off tests. Square cut all edges to be repaired a minimum of 15 mm deep, perpendicular to the surface, followed by the removal of all unsound material to a minimum depth of 15 mm. When using compressed air for cleaning, the air must be clean and oil free. Never feather edge the product. To seal leaks, crack openings must be chased out to approx. 20mm square. The chase should always be undercut to avoid leaving a v-section. All loose material and debris should be removed.

durarep 60 and 180 are generally mixed in small quantities for specific repairs. For this reason it is more practical to mix these products by volume as per the ratio: 1 part water to 3 parts durarep.

The water must be clean and of a potable quality. The product must be mixed to a thick putty-consistency very quickly and only a quantity which can be used immediately.

Work the mixed mortar into place using a gloved hand or trowel, exerting sufficient pressure to ensure complete wetting of substrate and required compaction before material can set. To plug running water, dry durarep 60 powder can be used directly onto the running water but must be held in place until an initial set has taken place. durarep 60 or 180 can be applied to horizontal, vertical or overhead surfaces at a wide range of thicknesses in excess of 15 mm. Generally, the volume of mixed material used in a single application is restricted to that which can be applied by trowel or gloved hand. The mortar can be built up to provide thicker sections. These products display heat generation characteristics in thick applications and, although they have been formulated to minimize the effect, high heat output (exothermic) could lead to severe shrinkage and consequent cracking.

durarep 60:

5 litres per 10 kg bag
12,5 litres per 25 kg

durarep 180:

5 litres per 10 kg bag
12,5 litres per 25 kg

durarep 60 and durarep 180 are supplied in 10 kg bags or 5 kg bags.

Surface and ambient temperature must be at least 5° C and rising, ideally between 20° C and 30° C. In colder conditions warmed water may be used to improve the setting times. At ambient temperatures above 35º C, the material should be stored in the shade and cooled water used for mixing.

durarep 60 and 180 products should be removed from tools, equipment and mixers with clean water prior to the initial set. Cured material can only be removed mechanically.

durarep 60

A rapid-setting one-component, cementitious blend, which sets rapidly after the addition of a minimal amount of clean water. The rapid setting mortar will be durarep 60, a rapid-setting single component chloride-free cementitious mortar having a setting time of one minute and applied in accordance with the recommendations of a.b.e.^® Construction Chemicals.

durarep 180

A rapid-setting one-component, cementitious blend, which sets rapidly after the addition of a minimal amount of clean water. The rapid setting mortar will be durarep 180, a rapid-setting single component chloride-free cementitious mortar having a setting time of three minutes and applied in accordance with the recommendations of a.b.e.^® Construction Chemicals.

These products have a shelf life of 12 months if kept in a dry cool place in the original packaging. In more extreme conditions this period might be shortened.

durarep 60 and 180 are alkaline and must not be allowed contact with skin and eyes. Avoid inhalation of dust during mixing by wearing dust masks. The use of gloves, eye protection and dust masks is advised. Immediately wash with water in the event of contact with skin. Splashes into eyes should also be washed immediately with plenty of clean water and medical advice sought thereafter. If swallowed, seek medical attention immediately -do not induce vomiting.
