APPLICATION GUIDELINES

• Ensure that the surface to be treated is free from oil, dust and other foreign matter.
• Apply Sika® CD Anti-Lime Coating at a rate of 2 – 4 square metres per kg using a brush or spray unit. Apply additional treatments if required.
• Allow 2-3 hours for the product to dry. After this period, check for any “puddling” of the product on the concrete surface. If “puddling” has occurred, apply water to the affected area and sweep the Sika® CD Anti-Lime Coating with a broom to allow further penetration in to the treated substrate.
• NOTE: Porous concrete may require subsequent applications; a trial should be conducted to assess the number of applications required.
• After Sika® CD Anti-Lime Coating has dried it may appear patchy but the appearance should improve after 2-3 months as the Sika® CD Anti-Lime Coating continues to react and release any trapped water.
• Do not allow Sika® CD Anti-Lime Coating to come in to contact with painted surfaces, glass or aluminum, as pitting may occur. If contact occurs, flush with copious amounts of water. Usage is not recommended where an aesthetic finish is important such as with coloured concrete.
   

LIMITATIONS

Do not apply Sika® CD Anti-Lime Coating in the following cases;

• To seal lightweight or other extremely porous masonry that contains actual holes and air pockets.
• When the temperature falls to below 5°C.
• To areas previously treated with curing or sealing agents, unless these coatings have been removed by chemical or mechanical means.
