Embedded steel reinforcing should be free from scale, rust, oil and grease, and treated with a suitable anti-corrosion coating such as SikaTop® Armatec®- 110 EpoCem®.

The application of a suitable bonding agent such as Sikadur®-32 LPor SikaTop® Armatec®-110 EpoCem® will improve adhesion on large areas or where particularly dense concrete substrates are involved.

Add water according to the desired consistency into a clean mixing vessel before slowly adding the SikaGrout®-113 PK powder. SikaGrout®-113 PK is best mixed in a forced action mixer, for 2 to 3 minutes or until the mix is free of lumps, not longer than 5 minutes. Slow speed SS paddle mixer (maximum500 rpm) should be used for mixing (aluminum paddle is strongly not recommended). Normal tumble type concrete mixers are not suitable. Do not mix more grout than can be placed within 15 to 20 minutes. Do not add extra water or other ingredients. Mix only full bags for best results.

Before pouring let the mixed grout stand for approximately 5 minutes after mixing to allow entrapped air to escape. Pour into the prepared area such that the grout has the shortest distance to travel. Ensure that air displaced by the grout is allowed to escape. When carrying out base plate grouting, ensure a sufficient head of pressure is maintained to keep the mortar flowing. All exposed areas of the mortar surface should be kept as small as possible.

Treat exposed surfaces with Antisol®-WB curing compounds or use other approved curing methods such as polyethylene sheeting or wet hessian. Do not commence fogging until final set has been reached.

Clean equipment and mixer immediately after application with water. Hardened material can only be removed mechanically.
