Gib Stoppers What to Expect When Skimming Walls:

Learn more about having your walls skim-coated in your home. Learn the right procedures and what you can expect from a skimming service.

Wallpaper stripping

If you’re doing the wallpaper stripping yourself, wet the layers and let the water soak in. This process can be accelerated by using a large wet sponge or wallpaper steamer. I prefer to soak an area multiple times before applying water. To save time, use the scraper to cut large pieces of paper. You can leave in place any stubborn layers or areas that are not moving. If they are properly prepared, they can be plastered over as long as they are not loosened.

Before gib starting

Clear the area before your Gib stopper arrives.

  1. To prevent dust damage, take electronic equipment out of rooms
  2. Take ornaments, wall hangings, and other small items out of your room
  3. If large furniture is placed in the middle of the room, they may be able to stay.
  4. To prevent dust from settling on furniture, cover it with sheets
  5. You can access the entire area at once. By breaking down the job into smaller pieces, you reduce the time it takes to complete the job.

Preparing walls and ceilings for skim coats

After removing any debris, your specialist will apply an oil-based pigmented sealer (OBPS). This sealer is used to bond and stabilize plasterboard, sealing in any old adhesives. It also prevents substances from reacting after the skim coats are removed.

OBPS is made from modified oils and can be very odorous when applied. We don’t recommend that you use the affected rooms during this procedure.

Steel slimlines for external corners

The gib stopper can fit any steel slimlines to any exterior corners (corners protruding in the room). These are designed to give a square profile and not a rounded corner or old-fashioned timber corner bead.

Strengthening the joins to stop cracking

Our specialist uses only perforated reenforcing tape made from paper-based materials to protect plastered surfaces long term against cracking. To ensure a strong bond, this is applied with high adhesive plasters. We do not recommend the use of fibre reinforcement tapes. Fibre tape is used by many best gib stoppers in auckland as well as most Auckland painters. This is either to lower labour costs or because they are not skilled enough to use perforated papers tape in certain situations. Fibre tape is obviously inferior. It is recommended against NZ25809/2007 (New Zealand Standards), and board supplier literature because the failure rate is high.

Use paper tape to reinforce and redefine internal corners

To create defined lines in the corners, we may suggest using paper reinforcement tape. This improves the room’s visual appeal and strengthens corners. We may also straighten plasterboard and framing that is out of line in order to minimize the appearance of defects. Some older homes have 1/4-inch round corner beads covering the internal corners. These should be removed before our gibstoppers start work.

Wall skimming

High adhesive compound is also used to apply the first coat. These compounds are stronger and more difficult to use.

The second coat is applied to the surface, and any tears or scratches in the paper. We will check for pin holes after this coat. Additional coats may be required for any pinholes. The final coats of skim should be applied in an air drying compound to cover the entire surface. We will again check for pinholes, and then cover them. Light checks are performed with a 500w halogen floodlight. This is to help identify areas that don’t meet our quality standards. Pinholes can sometimes form after final sand. It is best to seal the entire area. You can touch up pin holes without creating plaster demarcation lines.

Wall straightness

Framing defects are common in older homes. Skimming creates a smooth texture on the surface. Wall Skimming doesn’t create straight walls. Even relining might not correct framing deviations. We can feather out curves that are very obvious due to their shape or proximity to straight objects to minimize their appearance.


Skimming is a time-consuming job. Skimming a wall can take a stopper 3-4 times as long as it would to stop gib-stopping on the same wall. Multiple visits are required for even a small wall-skimming job. Skimming coat walls takes about one week. For a small room, it can take up to two weeks. If you have two people working on a half-house or more, the timeframe is one and a quarter weeks. These times are slightly longer to allow for drying.
