It is essential to ensure that faces of the joint are thoroughly primed and the back/bottom of the joint are not contaminated with primer. The concrete surface should be shiny after priming; if the surface is not shiny i.e. the primer has been absorbed into the concrete, another coat of primer should be applied. Any primed area contaminated prior to sealing by any foreign material will require thorough cleaning and repriming. Mixing Prior to any priming or mixing, check that the product being used is within its Use By Date; the Curing compound should preferably be with in 2 months of date of manufacture, good QA practice should be maintained i.e. batch numbers of the sealant should be recorded including the primer. Due to the short shelf life of the curing compound the product should only be ordered and delivered to site just prior to installation. If unsure, check with the local Parchem office. To facilitate proper mixing in cold weather, it is recommended that Emer-Seal 200 be stored for at least 12 hours at approximately 20°C prior to mixing. Thorough even mixing is essential to ensure proper cure. Mix only entire units to ensure correct proportions. During mixing ensure entire contents are fully mixed, paying particular attention to the sides and bottom of the tin. Avoid air entrapment caused by bringing the blade too close to the surface. Transfer all of Curing Compound into the Base tin. Hold the tin firmly and mix thoroughly using ONLY the recommended mixing paddle fitted into a heavy duty, low speed drill (300-500 rpm) until sealant colour is uniform and streak free. For mixing material, use a small mixing paddle (pc 770164), or large mixing paddle (pc 770163). Mix for 3 minutes then scrape down sides of tin. Mix for a further 3 minutes, total mixing time should be a minimum of 6 minutes. Be wary of excessive high speed mixing as high speed mixing may entrain air into the mixed material which may intern cause air voids in the joint. Incorrect mixing can adversely affect cure and final properties. Gun loading Ensure that the surface of the sealant is reasonably concave to prevent air pockets. Place the relevant follower plate on top of the sealant and load by direct filling of a Parchem G-Gun or into empty cartridges. Application Hold the nozzle against the joint, and gun sealant firmly into the joint extruding the bead in front of the gun to minimise voids. Wipe the nozzle occasionally to ensure a clean extrusion. Tooling To gain adequate surface contact between sealant and substrate and to eliminate air voids, tool sealant to a smooth finish with a slightly convex trowel. Remove masking tape if used. Cleaning Clean up uncured material and equipment immediately after use using Solvent 10. Do not use solvents on skin. Wash hands thoroughly with industrial cleaner. Limitations Not recommended for post-tensioned joints, or for use in highly chlorinated water such as in swimming pools. For advice on sealing such structures, contact Parchem’s technical department. Do not apply Emer-Seal 200 to any material containing mobile bitumen, nor allow bitumen to contact Emer-Seal 200. If likely to be in contact with other organic materials not specifically designed to be used with Emer-Seal 200, Parchem recommend initial testing to ensure compatibility. Estimating Supply Emer-Seal 200: 6 litre units (Base and Curing Compound supplied in correct proportions. Complete units to be mixed to ensure correct curing) Primer 13: 250 ml units (Base and Hardener, supplied in the correct proportions Complete units must be mixed to ensure correct curing) Primer 4: 250 ml units Solvent 10: 4 and 20 litre drums Quantities The table below gives some typical values: Joint Size Usage Width Depth Metres of joint / 6 litre unit 20 20 15 30 20 10 40 20 7.5 50 25 4.8 The above calculations do not allow for wastage.
