Safe Paint Stripping

How To Do Safe Paint Stripping?

A major concern when renovating our home was the removal of old paint on doors, windows, skirting boards, staircase and fireplaces. We had many layers of old paint on basically every surface in the house! Because the house was built so long ago, and because any previous updating work was probably done in the 1950s, 1960s and 1970s, we can be fairly certain that all of the paint is lead based.

Toxic Chemicals in Paints

A lot of people may not really believe that lead in paint is especially toxic or harmful as you would probably have to eat the paint to ingest any lead. But do you really want to take the risk? If we have children in the house in years to come why would we want to take the risk of them becoming ill? Chemicals in lead in paint are also potentially harmful to pregnant women – again why take the risk if it can be safely removed?

DIY-VOC

Over the years, due to regulations, paint strippers have become less toxic, removing some solvents and lowering toxicity. But of all of the paint strippers I looked at in builders merchants and DIY stores I was only able to find one other (DIY store own-branded) paint stripper that contained anything less than high VOC (volatile organic compounds) content. As regulations have changed, manufacturers have often simply removed one banned solvent, or substance, and replaced it with another that was probably just as bad and was probably banned at a later date.

I won’t claim to know all of the science and technical information involved in the dangers of lead paint but I know that I have the chance to be rid of these dangers now, whilst the house is being renovated. I would encourage anyone else, who is also renovating, and reading this blog, to give serious consideration to taking steps to remove any (even potentially) lead-based paint from their homes.

We decided that it would be best to remove all of the old lead paint, if possible, and re-paint with non-toxic paints. But it was always going to be a difficult task. As we’re trying to create an eco-friendly home, free from VOCs, we didn’t want to use any aggressive paint removal products as most of the off-the-shelf paint removal products are themselves very high in VOCs so using them would be counterproductive.

We wanted a paint remover that was solvent-free, non-hazardous and suitable for DIY use. It needed to be suitable for indoor use as we’re stripping lots of surfaces such as door frames or skirting boards that will remain in-situ. Also, as some of the work was done over winter it would have been cold outside. Whatever you’re doing, who wants to be outside or have the windows open if it’s cold or raining? So it had to be suitable for indoor use, without a nasty, toxic smell.

When you read on a label “use only in a well-ventilated area” what do you think? I think that if the manufacturers don’t believe that I should be able to breathe in the fumes of their product, then it can’t be safe can it? There must be a better, safer and more environmentally friendly answer. I simply refuse to use toxic products if at all possible. A little research of all of the different products that I could find resulted in nothing suitable until I found Eco Solutions Home Strip. Straight away I knew that I had found a safer, more eco-friendly alternative. It’s just down to how much time do you have? Are you willing to potentially pay more for eco-friendly products? Are you prepared to work a little harder if necessary? Hopefully, if you’re reading this I’m making this decision easier for you.

Eco-Products Home Strip removes lead-based paints, oil-based paints, solvent-based paints, water-based paints and emulsions as well as varnishes, waxes, fire-resistant paints and rust-preventative surface coatings. It’s suitable for use on many surfaces including hard and soft woods, marble, stone, brick, concrete, plaster, ceramic tiles, UPVC, GRP, aluminium, brass and other soft metals.

The VOC content is 0.000004% so you can work with it for as long as you like without ever fearing that you’re going to do yourself any harm and you needn’t have the windows open. Do you really want to burn your skin or breathe in hazardous fumes? I don’t. Certainly, we all get lazy and sometimes we forget to wear gloves or a face mask, but you should always work from the outset with a genuine good intention to work as safely as possible.

When removing lead paint, it is important not to simply try to sand it off by hand using sandpaper or by using an electric sanding tool as this creates dust with lead in it and this can be inhaled. In order to safely remove lead-based paint, you should keep it wet. Home Strip is similar in consistency to a gel. Once it has been spread onto the surface it keeps the paint wet. In order to ensure this, you can wrap the object being stripped in cling film – although this can be more difficult for things like door frames for example.

Home Strip eats away at the layers of paint and all of the lead content is encapsulated in the gel. It is then important to dispose of the waste correctly, at a local refuse centre that are able to handle lead paint products. You could safely wash Home Strip down the drain as it’s water-based, but the problem with this is that the lead-based paint that you have stripped is still toxic if released into the drains, so it should be disposed of carefully.

In my experience using Home Strip does require a little more time and effort than using a more aggressive, less eco-friendly product, but I was willing to take the extra time and put in the extra effort knowing that the result would be more environmentally friendly. I didn’t want to simply resort to using the easiest, most aggressive product that I could find to get the job done as quickly as possible – to the detriment of indoor air quality and the wider environment.

Home Strip did a quality, eco-friendly, job and did so without filling my home with toxic smells. I would happily use Home Strip in the same room as children, or in a room where I intended to sleep that same night, with the windows closed. I wouldn’t do this with other products. I felt no need to open a window or to ventilate the house whilst using Home Strip. It was almost totally odourless, in fact, what faint odour it did have I actually thought was quite pleasant and whilst the instructions did suggest using gloves I didn’t feel any real need to do so. I wouldn’t even consider using other paint stripping products without some sort of face mask, a fully ventilated room and gloves. We recently had some work done where a very commonly used adhesive was used and the whole first floor of the house smelled awful for several days, to the point where we didn’t want to be in the house. Home Strip does not create any toxic or unpleasant odour.

Types of Paint Strippers

Types of strippers: Strippers fall into three categories: caustic, solvent, and biochemical. There is no shortage of strippers to choose from. Many painters are loyal to one brand. If you’re not yet one of them, consult your dealer, quiz other painters, and experiment.

Here’s the range of answers I got when I asked several painters if they used chemical paint strippers:

  • “Never! Ever! It gives you brain damage!”
  • “Never! Well, except on concrete. Outdoors. And first, I get most of the paint off with a heat gun.”
  • “Occasionally, but only when I have to.”

After more conversations with painters and paint dealers, I found that many painters don’t understand how strippers work, or how to match a stripper to a job. Although many painters prefer to minimise their use of these chemicals, most painters must use them occasionally. So unless you’re a hard-core “Never! Ever!” painter, take the next few minutes to learn how to use strippers safely and productively.

Types of Strippers

Strippers fall into three categories: caustic, solvent, and biochemical.

Caustic strippers are water-based solutions with a pH of 13 to 14. Their active ingredient is lye, which may be either potassium hydroxide (known as caustic potash) or sodium hydroxide (caustic soda). When carrying out caustic paint stripping the lye reacts with the oily component of the paint film, turning it into soap. This reaction with the paint loosens it from the surface. The health risks of caustic strippers include skin burns and lung irritation.

Solvent strippers remove paint by dissolving or softening the bond between the film and substrate, causing the coating to bubble up. The most common solvent is methylene chloride (also called dichloromethane), but alcohol, toluene, acetone, and ketones are often also present.

Methylene chloride based strippers work very well. However, they pose more potent health risks than caustic strippers do. They temporarily reduce the blood’s capacity to carry oxygen and may cause permanent liver and kidney damage and cancer.

Another solvent is N-methyl-2-pyrrolidone (NMP), often used in combination with dibasic esters (DBE). Although these strippers are promoted as a safer alternative to methylene chloride, their health effects are not yet completely understood. According to the EPA, NMP causes skin swelling, irritation, and blisters. Dibasic esters cling nicely to vertical surfaces, but they work slowly and have been reported to fuzz the surface of the wood.

Yet another solvent system is a combination of alcohol, toluene, and methanol. This cocktail works quickly, but it evaporates quickly and is highly flammable. Breathing it can give you brain damage. The fact that it evaporates quickly reduces somewhat the volume of waste you must dispose of.

Biochemical-based stripping agents are another category. The solvents in them are derived from plants. Biochemical-based strippers may include terpenes, from pine or citrus; lactic acids, from corn sugars; dimethylsulfoxide (DMSO), from wood pulp and paper by-products; citric acid; and soy oil. Some of these materials can irritate your skin. In addition to the biochemical ingredients, most of these strippers contain NMP.

Although manufacturers of citrus-based products emphasise their suitability for commercial use, the paint stores in my town don’t report selling a lot of citrus-based strippers to professionals. If customers are concerned about odour, they may be happier if you use a citrus-based stripper. Remind them, though, that citrus-based strippers do contain harmful chemicals, and that the stripper will have to remain on the surface for a long time to work.

Strippers marketed as “safe” or “eco” don’t contain methylene chloride, but they may contain NMP, DBE, biochemical agents, or a combination.

Caustic Soda Paint Stripping

What is Caustic Soda?

Caustic soda (aka sodium hydroxide) is a very common chemical compound that is known to contain a very strong base, and as such could harm humans when mishandled. It has many uses for both industrial and domestic uses. However, due to its corrosive nature, it is best if Caustic soda, also known as lye, is handled by professionals.

Uses of Caustic Soda

Being a strong base, Caustic soda has many uses at the industrial level. It is used in the manufacture of cleaning agents such as soaps and toilet cleaners.

At home, it is used to unblock all drainage. A little quantity of caustic soda poured into blocked drainage pipes can clear the pipes of any blockages.

Caustic soda is also used as a paint stripper. When there is a need to remove paint on any surface including wood, metal, or any furniture caustic soda can come in handy when removing the old paint. When applied to the surface, it causes the paint on the surface to detach itself. This process is known as paint stripping. Caustic soda clears the surfaces of any paint.

Most people use caustic soda on door stripping. When they wish to change the paint on doors, they use caustic soda to remove the old paint from the doors. Caustic soda easily strips off paint from doors. However, handling caustic soda requires high levels of caution as it is a very corrosive chemical compound that is very hazardous to humans.

Health Dangers of Caustic soda to Humans

  • When caustic soda gets into contact with the skin, it causes serious burns to the skin. Therefore, protective rubber gloves should always be used when handling caustic soda.
  • When inhaled, caustic soda can cause serious respiratory problems.
  • When the vapours of caustic soda come into contact with the eyes, they irritate the eyes and in rare cases, can cause blindness.
  • When ingested, caustic soda can burn the digestive tract, causing serious health issues.

Since caustic soda can damage human’s health, it is best left to the professionals to handle it. Premium Door Stripping is a company that offers caustic soda paint stripping services. Our qualified experts have protective gear and are best qualified to handle caustic soda.

Accidents can happen anytime, and it is therefore not safe to have caustic soda at home. Contact Premium Door Stripping for all caustic soda paint stripping services. We remove paint on furniture, doors, metals, and any wood surfaces in a professional way, without causing any damages to the surface, or the people handling the caustic soda.

A caustic soda stripping tank is the most commonly used method to strip paint, lots of people say the stripping tank is an acid bath, in fact, it’s totally the opposite; caustic soda is an alkaline, it still burns like hell, as it’s highly corrosive but it’s not acid, therefore it doesn’t eat your doors.

There are two types of caustic tanks: Hot and cold.
The cold tank is only for metal items.
Metals can be stripped in a cold tank, as there is no risk of damage as these metals obviously aren’t porous. The hot tank can be used for both wooden items and metalwork.


Paint Stripping


Please note: you can not strip aluminium or aluminium alloys with a caustic stripping tank, it will damage it.

The heating of the caustic soda greatly accelerates the stripping process, making it a lot safer for the woodwork, as it’s in the solution for a lot less time.

Pine doors, windows, furniture, and woodwork strip really well, but these must be done in a hot tank, or there is a good chance the items will be damaged.

One of the most common asked questions to Premium Door Stripping is: does it loosen the joints or warp the doors?

The answer is no, not if it’s done properly. The only problems you may find is that on some furniture where the wooden blocks they used in the construction were glued with animal glue, and these can come off through the temperature of the liquid, so if the wood has lots of woodworm or rot and is soft, it may take forever to dry out – saying that, if it has an average amount of woodworm, it will kill the woodworm and prevent re-infestation.

You hear all these horror stories about pine stripping, if it was that bad, why would you have hundreds of antique dealers up and down the country using this method.  To have a good paint stripping tank, you must keep your caustic fresh and heat your tank really hot and keep it that way, and this costs a lot of money, then  the doors aren’t in the tank for long periods at a time.

When you get a recession or so-called “credit crunch” it seems that every builder, plumber and whoever hasn’t got a lot of work on, sets up a tank in his shed, after a while the caustic is old, he’s getting a bad name and not much work coming in, and can’t afford to heat the tank properly so the doors are submerged in the tank for half a day or even more, and the doors are ruined.
At the end of the recession, they get back in their Transit van and are gone, and we’re left with “doesn’t it loosen the joints and warp the doors”.

So always try to go to an established company with some history.

10 Tips for Safer Paint Stripping

For a successful repainting project, it’s important to start with the removal of old paint that has peeled, chipped, or bubbled. However, in the past, products designed to strip paint have tended to contain a potent chemical cocktail that was dangerous to both human beings and the environment. Fortunately, there are alternative methods available these days. Some are based on modern technology and others on good old fashioned elbow grease.

General Tips

  1. Be patient. Expect that paint removal with the help of elbow grease and/or non-toxic products is likely to involve increased physical effort and take longer to work. The good news, according t professional painting contractors, is that although safer paint strippers work more slowly, they do remove more paint in a single application.
  2. Wear safety gear. Protect your eyes, nose, and hands from flying paint dust or chips by donning goggles, a breathing mask, and heavy work gloves.
  3. Protect the surrounding area when working outdoors. Paint removers that are safer for human beings may still be harmful to your flowers and shrubs.

Elbow Grease Methods

  1. Scrub small spots with a Magic Eraser. A lightly dampened Magic Eraser is excellent for easily removing small drips and spills caused by latex paint. Just be sure to test it first on an inconspicuous area, as it can dull surface finishes. Magic Erasers and similar sponge-type products are made of open-cell melamine foam. While they feel soft to the touch, they actually work to clean up via their abrasive action. (And that rumor about Magic Erasers containing formaldehyde? Snopes debunked it years ago. As with sandpaper, just don’t try to use them on your skin.)
  2. Use a paint scraper. Pressure Wash your surface first, followed by scraping large areas of peeling paint with a putty knife. Bring out the paint scraper once you are no longer getting successful results with the putty knife. Draw the paint scraper down gently in a vertical motion. Complete the task by sanding with fine sandpaper.

Sand. Strip paint by starting with coarse sandpaper (24-grit) and gradually progressing to extra fine 100- or 120-grit, as needed. Use an electric sander for large expanses. Hand

Commercial Paint Removers and Strippers

  1. Look for products free of potentially harmful chemicals. Avoid methylene chloride, formic acid, carbonic acid, xylene, and toluene.
  2. Read labels carefully. Make sure that the paint remover which you are considering is suitable for your intended use.
  3. Try a soy- or citrus-based gel product. These paint removers are biodegradable but they still pack a powerful punch. (They smell better than the toxic varieties, as well.) The products can be rolled, brushed or sprayed on and after they’ve performed their task, scraped or pressure washed off.
  4. Loosen paint with infrared heat. Loosening with an infrared heat device, followed by scraping, can be used to remove paint, glue, or varnish. The substance must be heat-sensitive (unlike, for example, milk-based paint, epoxy, or shellac) for treatment to be effective. In some cases, application of organic linseed oil the preceding day will prepare the paint adequately. The appliance is expensive to purchase but also available for rental. (Some DIYers claim that a blow dryer can be substituted to give a similar, but cheaper method of paint stripping.) The surface will be ready for repainting immediately.
