PERFORMANCE DATA
U.S. Federal Highways Administration Test protocol for cracked Beam Concrete Test Method: Protectosil CIT was sprayed at the approved application rate onto standard test specimens where the concrete (W/C ratio 0.47) had been deliberately cracked along the length of the reinforcing steel to simulate real life experiences of transverse bridge deck cracking. Some specimens showed existing corrosion before application while others did not. The specimens were then subject to the following rigorous conditions: 48 weeks cyclic salt water ponding (15% salt solution) High Relative Humidities: 70 80% Elevated temperatures: 37C The results are summarised below Corrosion Inhibition Specimen conditioning Observed results compared with untreated control specimens 99% reduction in corrosion 92% reduction in corrosion
RECOMMENDED FOR
Protectosil CIT is sprayed directly onto the surface of steel reinforced concrete structures and buildings. It is equally suited to cast in situ, precast, post tensioned, prestressed, GFRC, or other steel reinforced concrete. It is particularly suited for the protection of: Bridge decks, piers columns and beams Multi-Storey Car Parks, building facades and balconies Marine jetties and structures Protectosil CIT can be used as part of an overall repair strategy using Emaco Concrete Repair Systems to mitigate corrosion rates within the balance of the structure and significantly reduce the possibility of ring anode induced spalling at a later date. Equally Protectosil Protectosil CIT can be used as a cost effective preventative measure before the onset of corrosion induced problems occur.

APPLICATION
Preparation of Substrate Concrete surfaces must be dry and cleaned to remove all traces of mould oil, curing compounds, dirt, dust, efflorescence, mould, algae, grease, oil asphalt, paint, lacquers, or other coatings or any other materials that would prevent penetration. Acceptable cleaning methods include shotblasting, high pressure water blasting, or grinding.
PROTECTOSIL CIT
All delaminated, loose or spalled concrete must be removed and repaired with an approved product from the Emaco or other approved Concrete Repair range. Protectosil CIT can, as an additional protective measure, be applied directly to exposed rebar before repair work commences. Non-moving shallow shrinkage cracks with no structural significance are simply treated with multiple coats or ponding of Protectosil CIT. CIT Other cracks or failed joint sealants should be routed clean and treated with Protectosil Protectosil CIT before being filled with suitable joint sealant from the Masterflex range or similar approved. Application Apply Protectosil CIT to the entire surface to be protected, including any repaired areas, using low-pressure spray equipment with a suitable fan nozzle. A total application of 600mL/m2 is usually required applied in two or three separate applications. (e.g. Horizontal applications 2 x 300mL while vertical and overhead 3 x 200mL) Allow a minimum of 15 minutes between coats (or until visibly dry). Application Watchpoints Do not apply at temperatures below 5C or over 35C. Allow concrete surfaces to dry for between 24 and 72 hours after heavy rain or cleaning with water before applying Protectosil CIT. CIT Do not apply if rain is expected within 4 hours. Do not alter or dilute the material as supplied.
PACKAGING

PRECAUTIONS
READ ALL SAFETY DIRECTIONS AND WARNINGS ON PACKAGING BEFORE USE. REFER TO MATERIAL SAFETY DATA SHEET FOR HANDLING PROCEDURES. As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs, (which may also be tainted with vapour until the product is fully cured and dried). Treat splashes to eyes and skin immediately. If accidentally ingested, seek medical attention. Keep away from children and animals. Reseal containers after use. Solvent Based Products Use in well ventilated areas; avoid inhaling. Suitable respiratory equipment may be needed, eg when spraying. Can cause skin, eye irritation. Wear protective eye shields and gloves during use. Do not smoke or allow sparks or naked lights when stored or in use. Spillage Chemical products can cause damage; clean spillage immediately.
COVERAGE
600mLm2 applied in two or three coats Horizontal surfaces: 2 coats @300mL/m2 Vertical or overhead surfaces: 3 coats @ 200mL/m2
