Your cracked and damaged walls have seen better days, and you want to make them nice and smooth ready for painting - covering over the holes, gouges and other damage caused by removing wallpaper or general misuse.

Step by step process
Cover all furniture and flooring.
Ensure the walls to be treated are clean, dry and free from mould and loose particles. Touch in any nails or screws with gloss paint to avoid corrosion, fill in any large cracks and seal any stains.
Stir the Polycell Smoothover for Damaged Walls to a creamy consistency.
Load the product onto the SmartRoller by immersing it fully in the product. No need to work off any excess, the roller will 'smartly' pick up the right amount of product.
Gently roll the Smoothover onto the wall, working away from the edges. Reload the roller and repeat, overlapping each section to ensure even coverage to a maximum thickness of 2mm. Each loaded roller should cover about half a square metre of wall.
After every square metre or so, use the SmartSmoother to scrape off the excess product, leaving a thin film across the whole wall. You'll get the best results if you smooth off in an arc, maintaining an even pressure as you go.
Don't worry about small irregularities or tramlines - these can be easily removed by light sanding once the Smoothover is dry, which takes about six hours.
Apply a second coat if needed - or get ready to paint.
