Remove all dirt, laitance, curing compounds, form release agents, loose materials and foreign matter from the joint faces. Remove all rust, scale and protective lacquers from metal surfaces. Non-porous surfaces should be degreased using Solvent 10. In all joints a bond breaker must be used to prevent sealant contact with the back of the joint, to allow optimum sealant performance. Deep joints should incorporate a backing strip such as Expandafoam or Stiffjoint to support the sealant while also acting as a bond breaker. Priming requirements Priming of porous substrates is always recommended, however good adhesion can be gained on concrete, timber, metals, ceramics, brickwork and most coating surfaces without the use of primers. Adhesion is improved with use of a primer. To achieve optimum adhesion to concrete and other porous materials use Primer 21; on non-porous materials such as metals use Primer 4. Primer 13 must be used on porous surfaces if the Emer-Seal PU40 is to be water immersed. Gun Loading Emer-Seal PU40 is applied using a suitable sealant gun. Insert the sachet into the gun, cut a slit in the top of the sachet, replace the end cap and apply the sealant. Application Extrude sealant firmly into joint to ensure complete contact with joint faces. Smooth finish if necessary with a spatula. Cleaning Clean tools immediately after use with Parchem Solvent. Limitations Do not apply Emer-Seal PU40 to bituminous surfaces nor allow bitumen to contact Emer-Seal PU40. Paintability - although polyurethane sealants will generally accept painting with acrylic coatings, it is possible for plasticisers to migrate over time and stain the surface of the coating. Parchem recommends the use of Emer-Seal MS in these applications. Supply 600 ml foil sachet, cartons of 20. Product Code 620600 Emer-Seal PU40 Conc.
