Sika MonoTop 115 GP is formulated for the repair of all types of concrete structures not exposed to water submersion. MonoTop 115GP is suitable for overhead and vertical repairs and hand applied repairs in exterior and interior environments. Suitable in place of R1& R2 mortars.
The concrete shall be free from dust, loose material, surface contamination and materials which reduce bond or prevent suction or wetting by repair materials.
Rust, scale, mortar, concrete, dust and other loose and deleterious material which reduces bond or contributes to corrosion shall be removed to a minimum standard of SA2½. Reference should also be made to BS EN1504-10:2003 for specific requirements.
Substrate Preparation/Bonding Primer/Reinforcement Coating
Delaminated, weak, damaged and deteriorated concrete and where necessary sound concrete shall be removed by suitable mechanical or very high pressure waterblasting [up to 110 mPa (16500 psi)] techniques. Tying wire fragments, nails and other metal debris embedded in the concrete should be removed where possible. The edges where concrete is removed should be cut at a minimum angle of 90o to avoid undercutting and a maximum angle of 135o to reduce the possibility of debonding with the top surface of the adjacent sound concrete and should be roughened sufficiently to provide a mechanical key between the original material and Sika® MonoTop®-115GP.
Ensure sufficient concrete is removed from around reinforcement to allow coating and compaction of the repair material.
Surfaces should be prepared using abrasive blast cleaning techniques or high pressure waterblasting [up to 60 mPa (9000 psi)] techniques. Where exposed reinforcement is contaminated with chloride or other material which may cause corrosion, the reinforcement shall be cleaned by low pressure water blasting [up to 18 mPa (2700 psi)].
On a well prepared and roughened substrate a bonding primer is generally not required. When a bonding primer is not required pre-wet the surface. The surface should not be allowed to dry before application of the concrete repair mortar. The surface should achieve a dark matt appearance without glistening and surface pores and pits should not contain contain water. When a bonding primer is necessary apply Sika® MonoTop®-610 (Refer to the relevant Product Data Sheet).
Site adhesion values - Structural Repair 1.2-1.5 mPa Non Structural repairs minimum value 0.7 mPa
Where a reinforcement coating is required as a barrier apply to the whole exposed circumference two coats of Sika® MonoTop®-610 or SikaTop® Armatec-110 Epo-
Cem® if chlorides are present.(Refer to the relevant Product Data Sheet). Reference should also be made to BS EN1504-10:2003 for specific requirements.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
Customer further agrees that Promain have no liability for any errors or omissions contained within the Product Data Sheets and are not liable for failure due to misapplication or inadequate substrate cleaning and preparation. For more information please refer to our Terms & Conditions.
