The Kit Room · 43 things, explained honestly
Brushes, roller sleeves, fillers, caulks, sealants and tapes. What each one is for, what it is not for, and the small things that separate a tidy job from a long weekend.
No brand names, no affiliate links. Just what we would lay on the bench for your job, and why.

Ask the bench
Tell us what you are working on and we will lay the right things out on the bench, with the reason for each. Change any answer and watch the list change.
The bench says
Wash, fill, spot prime the repairs, then two coats. Cut in first, roll while the edge is wet.
Synthetic brush, 2 inchBrush
Cutting in walls and ceilings. Dampen the brush and flick it dry before dipping. Load the bottom third only, tap both sides inside the kettle and never wipe the rim.
Angled sash brush, 1.5 inchBrush
Sash window glazing bars. Hold it like a pencil, not a hammer. Move from the wrist and let the long side of the angle draw the line.
Dusting brushBrush
Every surface, immediately before painting. Dust, then wipe with a barely damp cloth, then paint. Most rough finishes are dust trapped under the coat, not the paint.
Medium pile sleeve, 9 to 12 mmRoller
Emulsion on walls and ceilings. Before first use, wrap the sleeve in masking tape and peel it off to lift loose lint. Then roll a W, fill it in, and lay off lightly in one direction from ceiling to floor.
Extension poleRoller
All ceilings. A short pole, about 60 cm, is the most useful length in a normal room. Long poles are for stairwells.
Low tack masking tapeTape
Masking against paint less than a fortnight old. Press the edge down with a filling knife, paint a first coat of the base colour along the tape to seal it, then your line colour. That is how you get a knife edge line.
Sugar soapBench
Every previously painted surface before repainting. Wash from the bottom up so dirty runs do not streak the clean wall, then rinse from the top down.
Paint kettle and scuttleBench
Every job. Line the kettle with a plastic liner or a freezer bag. Change the liner, not the kettle, between colours.
Cotton twill dust sheetsBench
Floors and furniture in every room. Fold them paint side in when you finish and they last for years. Shake them outside, never in the room you have just painted.
Seven rules of the bench
Nearly every failed finish we are asked to look at broke one of these.
Decorators caulk goes black and soft in a bathroom. Silicone will not hold paint. Read the tube, not the shelf label.
Synthetic for water based. Natural bristle for oil. A natural brush in emulsion goes floppy in an hour; a synthetic in gloss drags.
Short pile on doors, medium on plaster, long on render. The wrong pile is the difference between a finish and a texture.
Shallow and still: fine surface. Deep and still: powder. Moving: flexible. Outside: two part or masonry. Old lime walls: lime.
Cement, gypsum and plastic paint on a lime built wall trap moisture and push the surrounding lime off within a few winters.
Wash, rinse, dust, then paint. Rake out failed sealant to bare material before the new bead goes in.
Paint over uncured caulk crazes as the caulk shrinks. Bare filler drinks paint and flashes. Spot prime every repair.

Every item says what it is for, what it is not for, and one thing we wish someone had told us sooner. Cost bands are a guide to what a good one costs, not the cheapest one.

The sleeve decides the finish. The frame just holds it. Match pile length to the surface and fibre to the paint.

The everyday sleeve for emulsion on plastered walls and ceilings. Holds plenty of paint and leaves a light, even texture.

No filler is right for everything. Choose by how deep the hole is, whether it moves, and whether it lives outside.

Gypsum based powder you mix with water. Strong, sands to a feather edge and can be built up in layers for deeper holes.
