Please Note: Blockade is not for exterior use, apart from spot priming resinous knots in timber.

For the best results, ensure surfaces to be coated are sound, clean, dry and free from all defective or poorly adhering material such as dirt, grease, paint or adhesives. If needed, clean surface using an appropriate ammoniated cleaning solution. Never use tri sodium phosphate based cleaners.

2. Sand all edges of remaining coating until smooth
3. Clean as much of the existing stain as possible, prior to priming

5. Fill any nail holes and imperfections with a suitable multi-purpose filler and spot prime the area
