Dean decorates new plaster, re-skimmed rooms and extensions in Wootton, about 2.4 miles south of Northampton town centre. Work here ranges from lime plaster repairs inside the old stone village to gypsum-skimmed extensions on Wootton Fields and Simpson Manor, and the two need different paints.
Lime or gypsum: find out before the first coat
The first question with any new plaster in Wootton is what the plasterer actually used. In the late 17th and 18th-century ironstone and limestone cottages of the old village, repairs are usually done in lime, because lime lets the solid walls breathe. Modern estate homes and their extensions are plasterboard and gypsum skim. Each takes paint differently.
| Plaster | Where you will find it in Wootton | How we finish it |
|---|---|---|
| Lime plaster patch or full re-plaster | Solid-walled cottages around High Street, Green Lane, Church Hill and Berry Lane | Limewash, or a breathable mineral or clay paint. Never sealed in with a vinyl emulsion. |
| Gypsum skim on old walls | Re-skimmed rooms in village houses and later infill | A breathable mist coat and finish, and a check for damp behind it first |
| Gypsum skim on plasterboard | Extensions, loft rooms and new partitions on Wootton Fields and Simpson Manor | Thinned contract matt mist coat, snagging, then two finish coats |
The general method for mist coats, drying checks and snagging is on our main new plaster and extension painting page, with more detail in the mist coat guide.
Why plaster dries slowly in the old village
Wootton sits on a gentle slope that falls south to Wootton Brook, and the village centre lies in a slight hollow. The water table is not far below the surface. The 1880s Ordnance Survey map shows 16 wells, and the stream along Water Lane now runs in a culvert. For a solid stone cottage that means walls that can hold moisture from below and from the weather, and new plaster on them takes longer to dry than the same thickness in a dry, modern house.
So on village jobs we check moisture readings at skirting level and in corners, not just in the middle of the wall, before painting. If an area stays damp, we tell you, because painting over it only hides the problem for a while. Lime plaster in particular can need weeks to carbonate and should then be finished with something equally breathable.
Extensions on the estates
On Wootton Fields and Simpson Manor, new plaster typically comes with a kitchen extension, garage conversion or loft room. These are straightforward to decorate once the skim has dried evenly and turned a uniform pale pink. We apply a thinned mist coat to everything, then fill and sand the hairline cracks, trowel marks and board joints it shows up. After that come two finish coats, plus priming and painting of new architraves, skirtings and window boards. Where the extension joins the original house, we paint the junction so the old and new walls finish the same colour and sheen.
- Plaster dried evenly, with no dark patches round sockets or in corners
- Mist coat on walls and ceilings, followed by full snagging
- New MDF and softwood sealed and primed before finishing
- Decorating sequenced around the kitchen fitter or flooring
New work next to listed fabric
Orientation affects drying too. Wootton faces south down its slope towards the brook, so a rear extension on that side with a roof lantern or bifold doors can get strong sun through the glass while the corners and the wall against the old house stay cool. Plaster in those spots dries last, and if the mist coat goes on too early it can blister or show darker patches. We take readings in several places, not just one, and in winter we ask for the heating to be on gently for a week or two before we start.
Twenty-five buildings in the Wootton conservation area are listed, and listing covers interiors. If a listed cottage is having new plaster or an extension, the finishes should have been part of the consent. We follow what was agreed and will not put modern sealing paints on historic lime walls. You can read about the village more generally on our Wootton area page.
