On concrete and masonry surfaces, Primer 10 is recommended to achieve the best possible adhesion. A primer must be used if the sealant is to be submerged for intermittent periods, such as joints in a flood crossing or in warehouse floors where chemical spillage may occur. Sawn joints in asphalt do not require priming provided that a large percentage of the joint faces are made up of sawn aggregate. Primer 13 must be used on both asphalt or concrete in applications where Roadseal SL is to be subjected to long term water immersion or on asphalt which has not been cut with a saw. If in doubt, consult your local Parchem sales office for advice on priming. Application Roadseal SL is applied from 600 ml sausages or bulk containers into the joints using a suitable sealant gun. On larger projects, an air assisted gun and pump may be used allowing faster application. Within 10 minutes after application, the sealant should be tooled in order to improve contact with the joint faces, and to lower the sealant surface to a level about 3 mm below the pavement surface. Equipment Complete high volume application units include an air powered pump, follower plate, hose, gun, and applicator nozzle. The extrusion pumps are available with various output capacities. The hoses and connections must not allow moisture penetration. Teflon lined hoses are recommended because of their low moisture permeability. It should be noted that the rate of sealant delivery is affected by air pressure, hose length, hose diameter and nozzle diameter. Clean up Equipment may be cleaned of uncured sealant by wiping, or soaking and wiping with Solvent 10. Any sealant allowed to cure becomes very difficult to remove and can only be removed using Solvent 10 in combination with steel wool. Limitations Joints in asphalt pavements must be sealed with Roadseal SL. The standard Roadseal product is designed for use in concrete pavements, has a higher tensile modulus and is not suitable for joints in asphalt. Other sealants from the Parchem range may also be suitable for use in asphalt roads. Roadseal SL may only be used without a primer in sawn joints which are clean and dry and where a large percentage of the sawn joint faces are made up of sawn aggregate. Where asphalt is not sawn or the aggregate content is low, Primer 13 must be used. Where asphalt is to be applied over a concrete pavement containing joints sealed with Roadseal SL, a siliconised paper bond breaker tape must be applied over the cured sealant to prevent direct contact with the asphalt and to prevent the asphalt from bonding to the sealant surface. In the case of joints wider than 10 mm a steel plate may be laid over the sealed joints to support the asphalt topping and to allow compaction of the asphalt. Where large joint movements may be experienced, joints in the concrete base slab may need to be carried up through the asphalt topping. Estimating Packaging Roadseal SL: 600 ml sausage (PC: 610407) 20 litre drum (PC: 610403) 200 litre drum (PC: 610406) Primer 10: 250 ml tin Primer 13: 250 ml pack (two-part epoxy) Solvent 10: 4 and 20 litre drums Coverage Each 20 litre drum will seal approximately 415 metres of joint with a 6 mm wide by 8 mm deep sealant bead. Storage Storage life of 12 months in original containers when kept in cool, dry conditions.
