Cleaning and assessment
Remove surface contamination and identify loose coatings, old filler, stains and weak areas.
The foundation of a better finish
Surface Preparation and Minor Repairs
Cleaning, filling, sanding, stabilising and priming selected to suit the actual surface—not a one-product shortcut.
Fresh paint highlights dents, cracks and uneven repairs rather than hiding them. Preparation is therefore specified around the condition of the substrate, the existing coating and the finish required.

Preparation matched to the defect and finish
Filling and sanding
Make good agreed cracks, holes and minor defects, then sand to an appropriate finish.
Sealing and stabilising
Treat porous or friable areas with a suitable system where the substrate can be made sound.
Priming and stain blocking
Use compatible primers for bare materials, adhesion, tannins or dry historic staining where required.
Preparation and process
Identify, stabilise and make ready for decoration
Identify the cause
Separate cosmetic defects from active leaks, structural movement or other issues requiring a different trade.
Agree the finish level
Discuss which imperfections can be improved and where more extensive plastering or repair may be needed.
Prepare methodically
Work from sound edges, build repairs in suitable stages and control dust where practical.
Test before finishing
Check repaired areas, primer adhesion and stain isolation before applying the decorative coats.
Practical planning
Agree the repair boundary before work starts
This service covers making good directly related to decoration. It does not present minor filler work as full plastering, structural repair or remediation of an active defect. Older or unknown coatings may also need a different approach before abrasion; HSE guidance explains why old paint can require caution.

- Minor plaster repairs
- Loose or flaking coatings

The Decor Plast standard
Make the background ready for the agreed finish
“Preparation” can mean cleaning and light filling or a more involved sequence of removal, stabilising and repair. The level is written into the quotation so the expected finish has a clear basis.
Defect and cause
Cracks, loose paint, stains and uneven areas are separated from movement, moisture or structural issues that need other work first.
Agreed repair level
Local filling, wider smoothing, stabilising, priming or stain isolation is specified according to the condition and finish expected.
Ready-to-finish check
The repaired background is reviewed for soundness and consistency before the agreed decorative coats proceed.
What shapes the quotation
The defect, repair level and finish tolerance matter
- Affected area, substrate and the extent of loose or failed material
- Crack pattern, staining, movement and whether the cause is resolved
- Dust protection, access and work around occupied rooms or fittings
- The agreed standard of local repair, smoothing and final decoration

Service questions
Useful answers about surface preparation
The inspection separates decorative making good from defects that need investigation or a different specialist before painting.
See general decorating FAQsCan you make every old wall perfectly flat?
The achievable finish depends on the substrate. Significant waviness or widespread failure may need a separate plastering scope before decorating.
Can old coatings always be sanded?
No. The coating and age must be considered. Potentially hazardous materials require an appropriate assessment and must not simply be dry sanded.
Why is primer needed?
Primers can improve adhesion, control suction, isolate staining or prepare bare materials. The correct product depends on the surface.
Can you fill cracks before painting?
Minor stable cracks can usually be prepared and filled. Repeated movement, significant width or structural concern should be investigated before a decorative repair is attempted.
Do you remove loose and flaking paint?
Unsound coating is removed back to a stable edge as part of the agreed preparation. Widespread failure may require a larger stripping or specialist scope.
How are stains prepared before repainting?
The source must first be resolved. Once the surface is dry and stable, cleaning, local repair and a compatible stain-blocking primer may be required.
