APPLICATION INSTRUCTIONS SUBSTRATE QUALITY / PRE-TREATMENT

Concrete The concrete must be structurally sound, thoroughly clean, free from oil, grease, dust, loose material, surface contamination and materials which will impair the grout flow or reduce adhesion strength. ▪ Laitance, delaminated, weak, damaged and deteriorated concrete and where necessary unsound concrete must be removed by suitable mechanical preparation as directed by the engineer or supervising officer. ▪ Any pockets or holes for structural fixings must also be cleaned of all debris.

Shutter Formwork Where formwork is to be used, all formwork must be of adequate strength, treated with release agent and sealed to prevent leakage of pre-wetting water and grout. ▪ Ensure formwork includes outlets for removal of the pre-soaking water or use vacuum extraction equipment to remove water. ▪ For manual grout application, a header box or hopper must be constructed on one side of the formwork so that a minimum grout head of 150–200 mm can be maintained during the grouting operation. ▪ MIXING IMPORTANT Do not add more water than the maximum specified.

IMPORTANT

Do not use continuous mixing equipment. IMPORTANT For large bedding holes and higher gaps or based on some specific customer requirements, duly washed coarse aggregates of size 6 mm down may be mixed with SikaGrout®-214 IN in the proportion of grout : aggregate = 2 : 1 (by weight). Trials are recommended to confirm suitability of aggregates to be used. Electric single or double paddle mixer 1. Pour around 80 to 90 % of recommended amount ofclean water into a clean mixing container. 2. Stir water slowly with a spiral paddle (< 500 rpm). Add the complete bag of powder into the water while stirring slowly. 3. Add balance quantity of water and mix continuously for 3 minutes to achieve a uniform and lump free smooth consistency. 4. Wait for 1–2 minutes to allow the entrapped air to escape. 5. Grout mixer IMPORTANT Product must be mixed using suitable grout mixing equipment combined with agitator for large volume mixing.

IMPORTANT

Volume capacity of equipment must be proportionally greater than the volume of material being mixed. Note: Equipment trials must be considered to make sure product can be mixed satisfactory before full project application. Pour the minimum water ratio in the correct proportion into the grout mixer. 1. While stirring the water, slowly add the powder to the water. 2. Add more water within the mixing time up to the maximum allowed until the required consistency is achieved. 3. Mix continuously for a minimum of 4 minutes. For larger mixes the mixing time must be extended to approximately 6 minutes or as necessary until the grout achieves a lump free smooth consistency.

APPLICATION IMPORTANT

Do not use SikaGrout®-214 IN for patch repair work or overlay in unconfined spaces etc. IMPORTANT Avoid application in direct sun and/or strong wind. IMPORTANT Protect freshly applied material from freezing and frost. Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions. Pre-wetting The prepared concrete substrate must be thoroughly saturated with clean water for a recommended minimum 2 hours before application of the grout. ▪ The surface must not be allowed to dry within this time. ▪ Before application of the grout, all water must be removed from within formwork, cavities or pockets and the final surface must achieve a dark matt appearance (saturated surface dry) without glistening. ▪ Placing: Manual application Apply the material within ~10 minutes after mixing to take advantage of the expansion properties. 1. Immediately after mixing, pour the mixed grout into the header box or hopper ensuring continuous groutflow during the complete grouting operation to avoid trapping air. Placing: Grout pump application For large volume placement, grout pumps are recommended. ▪ Equipment trials must be considered to ensure product can be pumped satisfactory. ▪ Surface finishing IMPORTANT Do not add additional water on the surface. IMPORTANT Do not over work the surface as this may cause surface discolouration and cracking. Finish exposed grout surfaces to the required surface texture as soon as the grout has started to stiffen. 1. After the grout has initially hardened, remove formwork and trim edges while concrete is ‘green’. 2. Cold weather working Consider storing bags in a warm environment and using warm water to assist with achieving strength gain and maintaining physical properties. ▪ Hot weather working Consider storing bags in a cool environment and using cold water to assist with controlling the exothermic reaction to reduce cracking and maintaining physical properties. ▪

CURING TREATMENT

Protect exposed grout surfaces after finishing from premature drying and cracking by curing under water for at least 72 hours. Keep exposed surfaces to a minimum. ▪ In cold weather, apply insulated blankets to maintain a constant temperature to prevent surface damage from freezing and frost.

CLEANING OF TOOLS

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