Application

Apply one coat of Envirograf® HWAP/WB clear Adhesion Primer at 10-12 m² per litre before applying HW02N, when the primer is thoroughly dry apply HW02N. HW02N is a clear Intumescent Coating with a slightly cloudy appearance but dries clear in about 1-2 hours. Once HW02N has been applied, do not attempt to re-work by over brushing this will tear the coating. If it is absolutely necessary to re-work then dip the tip of brush in warm water first and lightly brush over.

If using HW02N for the first time, it is strongly advised that you practice applying the product over a small area to get a feel for the amount of application needed. When happy with the finish on the test area, then proceed with the project. Ensure that the first coat is completely clear before applying the next coat. Apply 2 coats at 8 m² per litre, per coat to give 30 minutes on 9 mm softwood and 60 minutes on 14 mm softwood. Anything below these sizes, then apply 3 coats at 8 m² per litre, per coat. Can be applied by roller, brush or spray. If spraying add up to 10% water. The contents must be thoroughly mixed before use. Use a 2.5mm to 3mm nozzle.

For application to new wood – ensure that the area is dust free. Should you wish to stain the wood first, then we suggest using Sikkens Water Based Stains first. HWAP PRIMER MUST BE APPLIED ON CEDAR
