Removing Paint or Other Coatings from Timber Beams

For thick layers of indeterminate black coatings which have obviously been there for years, for gloss paints or other oil-bound coatings and some emulsion paints, Kling-Strip will give excellent results. It was for precisely this job that we first produced Kling-Strip over 39 years ago!

For polyurethane varnishes or other coatings etc Solvistrip can be effective.It is well worth trying both Kling-Strip and Solvistrip. In particular circumstances one will be more effective or easier to use than the other. Trial packs of all our products are available from our online shop.

Tip

Whitewashed beams (i.e. whitewash, not limewash) do not need any sort of paint remover: whitewash is water-soluble, it will come off very easily with a scrubbing brush, water and a sponge. We have often seen builders spending frustrating hours with a wire brush trying to clean beams exposed in renovation work. The wood is dusty and dirty; it needs a good wash. An ordinary scrubbing brush, water and a sponge will do a much better job in a fraction of the time and, unlike a wire brush, don't leave scratch marks in the timber! See Basic Principles.

How Long Will the Job Take?

For the average beamed ceiling with, say, a central beam with 12-14 joists on either side, the work on each joist, applying and washing off, will take approximately 1 hour's work from start to completely paint-free finish.

Will the Process Darken the Wood?

After washing off the dissolved paint, give the wood time to dry to allow its true colour to show. Medieval timbers are not generally darkened, although the colour of any timber may be altered by any paint-removal process. Old beams may naturally be any colour from grey to almost black. Often the colour of the wood can be lightened considerably with our Woodbleach A-B. The basic rule applies: do a test on a small area first with a trial pack available from our online shop.

Removing Paint or Other Coatings from Brickwork

With our products you can completely remove the paint or coating, even from soft red bricks, without marking, damaging or removing the face of the brick. The dissolved paint is simply washed from the pores of the brick. With no abrasives to pit the surface, no wire brushes to scratch it, brickwork can be left looking completely original, as if it had never been painted.

Which Product?

If the coating is very thick or is overlaid with other types of coatings, try different dwell times, including applying as thickly as possible and leaving overnight. Ambient conditions need to be cool and windless. Do a test patch first - trial packs are available from our online shop.

See also Limewash.

Important Points

  • Do tests first. On larger projects, make sure as far as possible that the area tested is representative of the whole area.
  • The basic principle when removing paint, coatings or grime from brickwork is that the coating or dirt should be dissolved or softened and then washed off.
  • Dirt and grime can often be softened adequately with water, while special products are available for stubborn or sulphated dirt (Please enquire).
  • For washing off use a pressure-washer, but only hold the lance close enough to the surface to wash it, not so near that it damages the brick.
  • The use of any sort of blasting, abrasives, wire brushes etc. for removing paint will cause irreparable damage to brickwork.
  • The paint/coating layer may comprise coats of different types of paint/coating, necessitating the use of more than one paint-remover (e.g. masonry paint over oil-based paint would require Solvistrip followed by Stripper 4-F or Kling-Strip).

Tips

  • Stripper 4-F can be spray applied, dramatically reducing application time, with suitable airless spray equipment. (Please ask for details of specifications for airless sprayers).
  • For internal work on small areas, Kling-Strip is usually easier to use than Stripper 4-F
  • Our VACWASH washer/vacuum cleaner attachment makes it possible to use a pressure washer in areas where the spray and runoff from a normal pressure-washer lance would be unacceptable.
  • Impervious exterior paint coatings are a common cause of what is often alarmingly rapid decay of exterior building surfaces, also of damp problems internally.
  • If it is essential to repaint, consider using limewash or lime paint, which are highly vapour permeable. For details of limewash and lime paint. Visit www.anglialime.com

Removing Coatings from Floor Bricks, Flagstones, Quarry Tiles etc

Which Product?

Tip

When using Adhesive Remover 510 or Solvistrip on floors, pour the product over a small area, let it find its own level and leave it to work. When it has done so, use a bit of cardboard to squeegee the product to the next area - only a little of it has been in contact with the floor, the bulk of it was simply preventing drying out, so most of it is still reactive. Then immediately clean up the dissolved coatings with hot soapy water, a scrubbing brush and sponge. This washing element of the process is quicker with a hot water pressure-washer, where it is possible to use one. Where it is not, our Vacwash attachment can often make it possible. See Basic Principles.

Removing Coatings from Glazed Tiles, Faience, Terracotta, etc

With our products, the dissolved coating is simply washed from the surface; so dense, smooth or glazed surfaces are particularly easy to strip.

Which Product?

Important Point

Do a test on a small area first - try a couple of products and see which one works best. Trial packs are available from our online shop .

Removing Paint or Other Coatings from "Modern" Plaster - Gypsum, Board Finish etc

Which Product?

Try applying as thickly as possible and leaving overnight - ambient conditions need to be cool. It will often come off as a sheet. Do a test patch first!

Tips

  • Do a test on a small area first. Try a couple of different products with different dwell times. See Basic Principles.
  • On flat surfaces, if preferred, the bulk of the dissolved paint can often be removed with a piece of stiff cardboard.
  • If using a metal scraper, be careful not to gouge tracks in the plaster - the paint-remover should do the work!
  • On flat surfaces, wash off with warm water (soapy for the solvent-based products, plain for Kling-Strip), scouring cloths ("Scotchbrite" etc), and a sponge. See Basic Principles.

Important Points

Do not try to remove paint or coatings from "dry lining" - plasterboard which does not have a finishing coat of plaster - it will go very soggy!

Removing Paint from Ornate Plasterwork

Which Product?

The thick layers of distemper and emulsion, which often completely clog and obscure the fine detail of ornate plaster cornices, friezes, ceiling roses etc., can be very effectively removed with Kling-Strip.

Tips

  • Because the coating layer to be removed is often in excess of 12mm (1/2") thick in the crevices, contractors involved in this sort of job tend to give Kling-Strip a dwell time of 5 to 7 days to work through.
  • With such coating thicknesses it is important to ensure that the product is applied particularly thickly.
  • Before repainting, make sure that the surface is completely dry and free from any efflorescence. The appearance of efflorescence usually indicates that the washing off of dissolved paint residues has not been thorough enough. Use an alkali-resistant primer.

Important Point

Plaster types can vary considerably. As always, do a test on a small area first to ensure that there are no ill effects. Make sure that the substrate (the surface underneath the paint) is indeed plaster and not "gesso" or "compo", "papier mach", "Lincrusta". etc. "Gesso" and "compo" will be softened by Kling-Strip. See Basic Principles. Papier maché, "Lincrusta" and embossed paper cannot be economically stripped.

Removing Paint and Other Coatings from Render

Our products enable the removal of multiple coats of paint from render and stucco without the use of damaging abrasives. The dissolved paint is simply washed from the surface, leaving it completely free of paint.

Which Product?

If the coating is very thick or is overlaid with other types of paint, try different dwell times, including applying as thickly as possible and leaving overnight -ambient conditions need to be cool and windless. Do a test patch first! See Limewash in Basic Principles.

Important Point

  • Do tests first. Trial packs are available from our online shop.
  • On larger projects, make sure that the area tested is representative of the whole area.

The paint layer may comprise coats of different types of paint or coatings, necessitating the use of more than one product. (e.g. masonry paint over oil-based paint would require Solvistrip followed by Kling-Strip).

Tips

  • Our Vacwash pressure - washer/vacuum cleaner attachment makes it possible to use a pressure washer in areas where the spray and runoff from a normal pressure-washer lance would be unacceptable.
  • Impervious exterior paint coatings are a common cause of what is often alarmingly rapid decay of exterior building surfaces, also of damp problems internally.
  • If it is essential to repaint, consider using limewash or lime paint, which are highly vapour permeable. For details of limewash and lime paint visit www.anglialime.com

Removing Paint from Steel Windows

The often heavy encrustation of paint on steel windows, being usually oil-based, is easily removed with Kling-Strip to give a completely paint-free finish.

Much quicker than the hours of tedious scraping necessary with other methods, and avoids the broken panes which inevitably accompany the use of blowlamps and hot air-guns!

Removing Paint or Other Coatings from Stonework

Unlike abrasive or mechanical systems, our products are well suited to removing paint from internal and external stonework. Only the paint is removed, not the surface of the stonework. The dissolved paint is simply washed from the pores of the surface, leaving it completely free of paint, so the surface is left intact. Our paint-removers are used on all sorts of stonework, from columns to quoins, from staircases to fireplaces, from vaults to windows, in everything from limestone to marble, slate to sandstone.

Which Product?

Tips

  • With coarse stonework, it is more difficult to wash off the dissolved paint with a scrubbing brush - the bristles skate over the pores of the surface. A pump-up garden sprayer often gives enough of a jet to help when doing the job by hand. A pressure washer will, of course, give rapid results where it is possible to use one. Where it is not, our Vacwash attachment can often make it possible. See Basic Principles .
  • Marble fireplaces are most rewarding items to remove paint from. The dense, smooth nature of the surface makes them particularly easy to strip provided, as always, that you use the right product for the paint you are trying to remove! They are usually coated with oil-based paint, so Kling-Strip is usually the product to use. Washing off the dissolved paint residues usually requires little more than a wipe with the sponge! The above applies equally to slate fireplaces. Cast iron ones come up well too.

Removing Paint from Woodwork

Using our products, you can completely remove paint from the grain of the wood. No scraping or sanding is necessary, so fine detail is not damaged.

Which Product?

  • A layer of old oil-based gloss paint up to 2mm thick can be removed with one application of Kling-Strip, making it possible to efficiently strip architraves, skirting boards, stairs, bannisters, panelling, doors, windows etc.
  • Old beams can be stripped very effectively with Kling-Strip where they are coated with "old" paint. Some emulsion paints can also be removed with Kling-Strip, especially where there is an underlying coat of oil-based paint. Kling-Strip also provides a safer system of removing paints containing lead. "Old" varnish, scrumble glaze etc. are readily removed with Kling-Strip.
  • For thin layers of old varnish from most types of solid wood paneling try Stripper 4-A.
  • Woodstain can be in many forms and is usually removable with Kling-Strip.

Do the tests in an inconspicuous area in case of discolouration of the wood.

Important Points

  • Always do a test on a small area first.
  • Trial packs are available from our online shop.
  • Enrichment or relief decoration on architectural woodwork, picture frames etc, is often gesso.
  • Such woodwork is generally coated with oil-based paint which would be effectively removed with Kling-Strip however gesso is also oil-bound so will be softened by the process.
  • The colour of some timbers may be affected by the paint-removal process.
  • If tests prove successful in removing the paint but you are unhappy with the colour, try our 'A&B' Woodbleach A-B.
