A Major Wall Surface Defect that Will Cost You Money

When the sheets of drywall are placed together, they are ‘finished’ with drywall mud (a gypsum product) and these areas are sanded flat prior to painting.  SOME TIMES the drywall finisher crews or the painters DO NOT SWEEP-OFF THE SANDING DUST from the areas where the drywall sheets are joined together.  When this happens, any paint that is applied to these (‘un-swept’) walls only lightly adheres to the sanding dust areas (especially so in the case of walls painted with airless paint sprayers).  This is a major disaster, as you will see the painted surface of your wall come off with (and on the back of) your wallpaper.  While you may think – “So what!” – the reality is that ‘paint’, although seemingly a rather ‘thin’ or inconsequential layer on your walls, actually has a ‘thickness’ that you can easily ‘see’ when it is removed from your walls.  This means that you will have to do ‘something’ in order to replace this ‘missing’ paint layer (which in the case of failure to adhere to your walls due to sanding dust not being swept off – will create an unmistakable ‘H’-pattern all around your room/s).  You see, the 4′ x 8′ drywall sheets are applied in a certain pattern and if the sanding dust is not carefully cleaned off the gypsum-finished edges– the pattern of the edges of the sheets can be seen… and this pattern often looks like a series of very large Capital ‘H’s on your walls.  This very thin missing layer of paint must be filled-in with drywall mud and then sanded smooth to match a flat wall or re-finished to match a textured wall.  This can be an expensive proposition and has NOTHING to do with wallpaper removal and has EVERYTHING to do with a general contractor or painting contractor who did not do their job properly.  Good luck at your house!
