These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level, overlaps and wastage etc.

• The substrate must be clean, dry and free of all contamination such as dirt, oil, grease and coatings etc. which hinder an adhesion.
• The substrate must be sound and of sufficient strength of min M25 Grade(25 N/mm²)^. Also minimum Pull Off Strength must be 1.5 N/mm²
• Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed.
• All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.
• Repairs to the substrate, filling of joints, blowholes/voids and surface levelling must be carried out using appropriate products from the Sikafloor®, Sikadur® and Sikagard® range of materials.
• High spots must be removed by e.g. grinding.

Prior to application, stir Sikalastic®-450 (I) thoroughly in order to achieve a homogeneous mix.

• Apply primer coat of Sikalastic®-450 (I) with 50% diluted with clean water, which will cure in 2-4 hrs depending on the atmospheric conditions, with an approx. consumption of ~0.25 kg/m² with a hard brush, roller or airless spray.
• Apply the first coat of approx 0.50 kg/m² of Sikalastic®-450 (I), then apply Sika® Fab-1 on the surface and ensure that there are no bubbles or creases. Overlapping of the Sika® Fab-1 is minimum 50 mm, allow this coat to dry for a period of 24 hours atleast depending on the atmospheric conditions.
• Apply second coat of approx 0.50 kg/m² coat to achieve the required film thickness.
• Do not spoil the dry surface while walking on it for application. Material should be applied within the workable time.
• Full curing may take upto 7 days depending on temperature and humidity.

Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
