Bleeding
Bleeding is the discolouration of new paint which can occur due to underlying stains underneath the coating. Affected areas should be treated with Stain Block Primer prior to repainting.
Cracking/Crazing
Should any splits begin to appear in the paint film, it should be abraded and filled as required before repainting.
Cracks
Fine hairline cracks can appear when painting new plaster. If this occurs, they should be filled with a suitable filler following the first coat of paint and then abraded lightly before coating with an additional coat of paint.
Efflorescence
This is a white, powdery and fluffy substance that is sometimes found on the surface. This should be removed by dry brushing until the deposits fail to reappear
Flaking Paint
If the surface has been previously painted, some detaching of paint from the surface may occur. Prior to applying a further coat of paint, all loose and flaking paint must be removed.
Grinning Through
If previous paint can still be seen beneath the new coating this is usually as a result of not applying the paint evenly or brushing out too much. If this occurs, further coats should be applied.
Moisture
If the surface is too wet to paint, it should be left to dry out before any paint is applied.
Mould/Mildew
Should fungal growth occur this will require treating with Sterilisation Wash and removing prior to painting.
Nail Holes
Movement of boards can cause holes to appear, if this occurs, bare plaster should be touched in, allowed to dry and then filled with interior filler.
Plaster Fines
When painting plaster, there can be a powdery residue on the surface. This should be removed with a dry brush or a cloth prior to painting. It must not be abraded with sandpaper.
Porosity
Porosity will affect the absorption of paint coatings. If a surface is porous, the first coat of paint should be thinned down or a suitable primer should be applied.
Blistering Wallpaper
This can be caused by either poor application of adhesive or poor surface preparation. To remove the blister, carefully cut open the blister, apply paint to the back of the paper and the wall, allow to soak and smooth back.
Wallpaper Edges Lifting
This can be caused by the poor adhesion of old wallcoverings and should be stuck back with new paint.
Tackiness
Using Vinyl Soft Sheen or Vinyl Silk on a blown vinyl, can sometimes be tacky. To avoid the tackiness, an initial coat of Vinyl Matt should be applied.
Uneven Appearance of Paint on Wallpaper
When painting blown vinyls or embossed wallpapers, the paint can sometimes appear patchy or the emboss is not filled adequately. In order to avoid this, the correct roller sleeves that suit the emboss should be used.
