Condensation, Painting and Decorating

Condensation, Painting and Decorating walls & ceilings

Damp on the inside of an exterior wall is sometimes blamed on water penetrating from outside or rising from
the ground when the real cause is condensation. Cooking, washing, etc – it all produces water vapour which condenses on cold walls.

Totally blocking up fireplaces and draught sealing windows and doors, makes it worse, because with no draughts there’s nowhere for the water vapour to go. In London, fireplaces are not so much in use lately. Anything which keeps surfaces in the room warm will help. Double-glazing prevents condensation inside windows and lining cold walls with a dry wall ( stud wall ) and insulation stops the damp from settling there. It also helps with soundproofing the walls.

Damp patches: some alternative barriers

Where the amount of damp coming into a room is slight, it can be kept from spoiling the decorations by applying any waterproof barrier between the plaster and the paper. Ask your builder’s merchant what he has in stock and what he would recommend; the materials range from paint-on waterproofing liquids, through pitch-coated lining papers to metal foils and foil-surfaced plasterboards. Pitch-coated papers are applied with a special waterproof adhesive; so are metal foils – the adhesive used with these dries quickly and you’ll need to smooth the foil out at once, working gently with a soft cloth to get rid of any air bubbles, before it has dried. Overlap joins by about an inch. If you tear the foil, stick a strip of foil at least an inch wide over the tear. The foil surface can then lined and painted, or wallpapered. Nail or stick foil backed plasterboard in place, foil side towards the wall. This will act as a barrier against the damp soaking through and help protect inside surfaces against the formation of condensations.

Stain blockers can be used before painting, however, sometimes the damp stain will show through the final painting coats in time, if the damp problem has not been solved before painting and decorating. You might need professional Painters & Decorators for the job.

Damp Stains Interior Decorations Walls & Ceilings

Keeping damp stains off interior decorations

The answer of most Painters and Decorators to the problem of damp spoiling interior decorations and plaster is a waterproofing lath material, made from a waterproof fibre sheet which lets air pass between wall and plaster, and makes a key for replastering or mounting plasterboard sheets;

You can get it from any builder’s merchant in rolls. But remember, interior treatment keeps damp from the interior surface of the room – it does not make the main wall dry. Sometimes waterproof rendering and one coat of water proof plastering can solve the damp problem before painting and decorating a wall.

Hack off plaster from damp wall, back to the brickwork, and a foot or so along any wall which joins the damp wall.Since wall will go on being damp, it’s worth painting it with a fungicide to sterilise bricks.

External Walls, Painters & Decorators

Preparing and Repairing the outside walls

Rendered walls have a layer of cement-sand mix mortar on top of the structural brick or blocks, rather as interior walls have a layer of plaster. Except in rare cases where they have already been painted with gloss paint ( when you will be able to clean down and put on another coat of paint ) they are usually decorated with a cement based paint, a paint containing sand to give texture or with emulsion paint, which is cheap and holds well to masonry surfaces even out doors.
painting external walls rendering
The Painter & Decorator, before starting work must tie back any wall plants and wrap them in plastic sheets. The floor must be protected in dust sheets too, don’t use plastic sheets as it can become slippery and dangerous. Scrape off any lose or flaking paint.

Small cracks in rendering can be repaired like internal plaster cracks, except that the filler must be one prepared specially for outdoors use.Larger areas of rendering that have failed should be hacked out until a firm edge is reached and then primed with a PVA & water mix for a good key and seal the dust. Then filled with a not-too-wet mixture of one part masonry cement to five parts soft sand. This put on with a steel float. If the rendering is much more than half an inch thick, do it in two coats, scoring the first one as it dries to provide a key for the second.

If the rendering is textured try to match this with the edge of the float or a brush. Pebbledash is rendering sometimes pre-mixed with small stones, but more usually applied flat and having small stones flung against it from a shovel and pressed in with a float.Examine it careful if you want a good match.
pebbledash rendering

Brush down walls to get rid of dust and apply masonry sealer if the surface is powdery. Repaired cracks and other bare areas should be given and undercoat of emulsion paint. A surface which has never been coated before should be wetted a square yard at a time before painting. If it has been painted but is very absorbent thin the first coat by 10 % or so.
The second coat of paint, ( you will need two or more coats of paint )should be put on full strength. Where possible, don’t let an edge dry before paint the adjoining section.

Professional Painting and Decorating

Professional Painting and Decorating – Painters and Decorators

Experience has taught many Painters & Decorators experts, the easy way to Painting & Decorating like a expert. You hardly ever see a professional painter and decorator painting straight from the tin. The Decorator or Painter uses a paint kettle ( any container with a handle ) which can be cleaned out every night. The Painter strains his paint into the kettle through an old stocking if necessary, so dust and bits of paint skin never spoils the new paint work.

When he stops for tea or lunch break, the decorator keeps his brushes from drying by suspending them into the paint by a wire through a hole in the handle or by wrapping them into a plastic bag. When the work day is finished, the Painter & Decorator he washes them thoroughly, first in thinners ( white spirit ) then in water, flicks the water out and hangs them to dry. Always wipe the brush on the same side of the kettle, so the other side stays clean and so does the paint kettle handle.

Keeping an striping knife, helps when you need to scoop up any paint that accidentally gets in the wrong place. It is a good idea to run in new brushes. Always wash new brushes before use, and use them first for primer and undercoat painting.

Masking tape makes windows painting easier, but nothing can beat a steady hand. For stairs, casements windows and doors, paint your way down and tackle awkward bits first. If you paint sash windows, be frugal with paint around the sliding parts or they may stick.

painters decorators

Paint large areas a bit at the time, vertical stripes first, the cross strokes to join them without putting more paint on the brush or rollers, then laying off, smoothly gently back into the painted area.
Limit yourself to an area small enough not to be dry before adjacent squares are started, or you will get a hard line of paint showing between the sections. The faster the paint dries, the smaller such sections should be. Timber and wood is best finished by painting in the same direction as the grains.

There’s more to walls, especially old fashioned walls, than you think. When the London Painters and Decorators are painting a room, ceilings always comes first to make sure the walls are not getting stained before they are painted. Then walls if they are to be painted, then the woodwork. If the walls are to be wallpapered, then they come last, after all the paintwork is completely dry.

Repairing plaster cracks before painting & decorating

Repairing plaster cracks before painting & decorating

With any plaster repairs, hack away any loose or damaged material with a bolster and hammer, brush away dust, damp broken surfaces and area using a PVA mix with water. Pick up plaster on the underside of the trowel and press into hole, adding more until not quite level with surrounding good plaster. Leave to harden, scratching lines to make key for top layer. This is best put on with flat face of a stripping knife, finishing by smoothing with the knife wet. Plaster will stick to a dry blade.

When the final layer is dry, sand down the wall using sandpaper and use wall filler to get a good finish, before sanding down the excess filler. The wall crack then needs a coat of primer or undercoat before the final painting coats can be applied. It is very probable that the whole wall will need to be repainted in order to match the paint colour, at least professional painters and decorators should opt for that.
