Paraffin wax

Firstly, the surface has to be well prepared to accept a liquid coating. Where a bitumen coating is already down it should be thoroughly brushed/scrubbed to remove any loose or blown bitumen. Some of it will still be bonded very well and that is fine. It should also be jet washed to be clean and free of dust and dirt. This is a bitumen like substance that was commonly used around edges of rooms and then the central area of the room would have rugs, during Victorian times. As you have discovered it is difficult to remove and my best advice would be to scrub with cellulose thinner and then sand.

We get a steady stream of customers asking us for advice about paint stripper use and how to remove paint and varnish from wood. Thankfully contemporary stripping products are relatively simple, effective and safe to use. Much better than the bad old days when your only choice was pure caustic soda, nasty stuff!

You can strip any kind of wood, even heavily-carved wood, as long as you use the right products and materials and follow the instructions meticulously, particularly if you want to strip something expensive, rare or precious.

There are three ways of removing paint from wood: sanding, using a hot air gun and chemical paint strippers. Protect the floor with dust sheets or thick newspaper. To get a chemical stripper into nooks and crannies on intricate woodwork, use wire how to make a supercomputer at home. Solvent paint removers take off all kinds of finishes, even contemporary ones.

On the downside, you tend to use more of it, so it can end up more expensive than a caustic stripper. Solvents can also have a strong odour and must only be used in very well-ventilated areas. Last how many pounds make one ton all, you might have to work a bit harder to remove heavy paint build-ups than with a caustic paint stripper.

So to sum up, solvent strippers are:. Caustic paint removers take off most finishes and are particularly good at getting rid of thick layers of paint and varnish.

They give off fewer fumes than solvent-based paint strippers, are cheaper and tend to work faster. On the other hand, caustic products usually contain a very strong alkaline which may react with chemicals in the wood resulting in staining or scorching of the how to make fabric rose buds. This is more common with dense woods such as mahogany and some types of Oak, especially old Oak.

In summary, caustic removers are:. You can always test drive a few different products to see which stripper best suits the job and matches your capabilities. Just carry out testing in inconspicuous areas and keep your test areas small. You can pick up a lead testing kit at your local decorating centre or DIY store. Chemical paint stripping and varnish stripping products partially dissolve the paint or varnish. Paints and varnishes have evolved over the years, so have their formulations and chemical make-up.

Paint strippers and removers have how to install j-molding around windows had to evolve to keep pace with these new formulations.

The same applies the other way round, where strippers that are effective against old paints may not be as effective on new paints and varnishes. So what is the answer? Paint strippers and varnish removers are usually available in sample or small tin sizes of between ml to ml.

Our recommendation is to buy a sample or small tin and to trial the effectiveness of a product before committing to buying the quantity of wood stripper needed what can 1 year old babies eat the project.

This could save time and money in the long run. We highly recommend Paint Panther Paint and Varnish Removerone of the best wood strippers on the market for day to day paint and varnish removal.

We also love PeelAway 1 and PeelAway 7which are both used to restore antiques and items like decorative or carved fireplaces, wooden or plaster coving, cornices and ceiling roses. Left for a period of between 12 and 48 hours, the PeelAway poultice dissolves the many layers of paint accumulated over the years. The dried poultice is then removed with a spatula, pulling out the dissolved paint from deep detailing, nooks and crannies to restore the intricate detail and design of the original piece.

For some projects you how to remove bitumen from plastic need to bring both into play, using PeelAway 7 on the newer layers and PeelAway 1 on the deeper layers. PeelAway 1 is caustic-based, so always try a test patch first.

Remember, caustic-based strippers can scorch the surface of some woods, such as old Oak and Mahogany. Both PeelAway products are available in a handy PeelAway 1 and 7 Sample Twin Packmaking it easier to test each product to find out which works best for your paint removal project.

All PeelAway products are supplied as a kit including an application spatula and protective blankets, to prevent the applied poultice or paste from drying out too quickly and before it has dissolved the paint or varnish. These are useful if the protective blankets need to be cut to shape or into strips for metal pipes, table legs or other required shapes. See our full range of paint, varnish, wax, stain and polish removers to find the product for your interior, exterior restoration or renovation project.

Just contact our team of wood finishing experts. Alternatively, visit our wood stripper and remover FAQ page which covers many of our most commonly asked questions. We love to see before, during and after photos of any wood finishing project.

HiI have solid wood garden furniture and it has a few layers of paint which is looking bad and peeling off. What would be the quickest method to strip it down to its original wood colour. A common issue and can be tricky with garden furniture if it is slatted for example. Best method can depend on the extent of the peeling, a hard bristled brush can help to remove a lot or a pressure washer, although take care not to hold the nozzle too close to the wood, as it will cause damage.

And if all of that does not work then you could consider a stripper such as the Barrettine Paint Panther Paint and Varnish Remover a gel that makes paints bubble up to be scrapped off.

Depending on what you are looking to apply once stripped, and the condition of the wood, you may also need to consider some light sanding. And if you need any advice on products to retreat the furniture with please do get in touch via our contact us page.

Dear Samantha, I have recently been trying to strip paint from a staircase and have a problem. The staircase had only been painted down the sides, leaving a space in the centre of each step which would have been covered by the runner down the middle of the stairs. The problem is that the stripped section at the sides, having been blasted with paint stripper to get the paint off I estimate three coats is now a much lighter shade than the middle, which I think may have been darkened by the application of carpet glue when carpet was originally fitted.

I have called in reinforcements of paint stripper, backed up by the coarsest sandpaper known to humanity and vigorous use of a wire brush.

But I am still left with a clearly-visible phantom carpet running down the middle of the stairs. This is after three full days of work!! Is there anything I can do apart from applying dark stain? The wood is I think pine, or possibly deal. Many thanks, Douglas Evans. A common problem unfortunately. The carpet runner has a lot to answer for when it comes to wood staircases.

The wood being covered by carpet will age differently to the areas that are not covered, even if they have been painted. Contact with the air and UV, or lack of it, will mean that the wood ages differently and this is why you have such a difference in appearance.

If extensive sanding has not solved the problem I think you are unlikely to be able to get a more even finish. Many people try staining to bring the two areas closer in finish but this is also a difficult job and wood can be unpredictable. You could take a look at the Manns Classic Pine Stain its a very versatile stain that can be applied in a number of layers to intensify the colour, or it can be intermixed to create an alternate colour, it can even have water added to lighten the tone if needed.

Test area will be vital and that should include your topcoat product of oil or varnish as this will also impact on the final colour. Good luck and I hope you are able to get the look you want, if you have any further questions please do not hesitate to let me know. Hi, I have some really intricately carved wooden screens. What is the best way to strip them back to bare wood so that a finishing oil can be used?

We have a couple of stripper that you could consider, the first is the Peelway 1 and 7 Sample Pack The Peelaway 1 for older paints and the Peelaway 7 for the more modern finishes. The Sample pack is deal for trying a test area first to see if this is the right product for your project. It is a poultice that you leave on the surface for 24 Ч 48 hours, covered with a piece of paper.

This product is great for intricate areas the only warning will be that the Peelaway 1 is not suitable for use on some hardwoods such as Oak or Mahogany as it can burn the wood. This is another reason for test areas.

There is a great video on the product page to show how it is used. An alternate and quicker product to consider is the Paint Panther Paint and Varnish Remover this is a gel that makes the paint or varnish bubble up to be scraped off, could be difficult with intricate areas but is a quick and effective stripper.

Again a test area should be carried out. I hope that helps and if you have any questions at all please do not hesitate to get in touch via our contact us page.

Apologies if this is not the correct forum for my question. I need advice on how to remove paint from a ceramic butler sink sink is likely to be around 50 years old. There is an enormous build-up of mostly water-based paint as sink used in an art classroom and has years of paint build up. Any advice on the best method to remove would be greatly appreciated, or point me in the right direction of a specialist who could do this.

Thank you for getting in touch with your enquiry. You could consider the Peelaway 1 and 7 Sample Pack this is a stripper for a wide range of projects and surfaces. I have not had any feedback on use on Butler Sinks and so as always a test area is strongly recommended somewhere inconspicuous. To see how it works, my main concern would be if it impacts on the finishing glaze that is actually on the sink also being lifted away.

So test should be done with care. What is multipart form data hope that helps and if you have any questions please do not hesitate to get in touch via our contact us page.

Hello there! I recently chalk painted an antique sewing table. The front door on the table has a beautiful herringbone design in the inset and I painted it without thinking new to painting furniture! Thank you so much! I really enjoyed your article! Bridgit Wallace. My apologies for the delay in getting back to you. Chalk paint, being water based will often come off with a good scrub with some soapy water, and perhaps some light sanding.

Its a great product for giving a matt coloured finish but in terms of protection is quite minimal. If scrubbing with warm water does not remove it all then you could have a look at a stripper such as the Barrettine Sample Twin Pack the Peelaway 7 is the one you want to try as it is for more modern paints.

Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal or oil shale that consists of a mixture of hydrocarbon molecules containing between twenty and forty carbon atoms. It is solid at room temperature and begins to melt above approximately 37 ∞C (99 ∞F), and its boiling point is above ∞C ( ∞F). Common applications for paraffin wax include lubrication.

Paraffin wax or petroleum wax is a soft colorless solid derived from petroleum , coal or oil shale that consists of a mixture of hydrocarbon molecules containing between twenty and forty carbon atoms. It is distinct from kerosene and other petroleum products that are sometimes called paraffin. Un-dyed, unscented paraffin candles are odorless and bluish-white. Paraffin wax was first created by Carl Reichenbach in Germany in and marked a major advancement in candlemaking technology, as it burned more cleanly and reliably than tallow candles and was cheaper to produce.

Paraffin is unaffected by most common chemical reagents but burns readily. Paraffin wax is an excellent electrical insulator , with a resistivity of between 10 13 and 10 17 ohm metre. It is an effective neutron moderator and was used in James Chadwick 's experiments to identify the neutron. Paraffin wax is an excellent material for storing heat , with a specific heat capacity of 2. Paraffin wax was first created in by the German chemist Karl von Reichenbach when he tried to develop the means to efficiently separate and refine the waxy substances naturally occurring in petroleum.

Paraffin represented a major advance in the candlemaking industry because it burned cleanly and reliably and was cheaper to manufacture than any other candle fuel. Paraffin wax initially suffered from a low melting point; however, this shortcoming was later remedied by the addition of harder stearic acid.

The production of paraffin wax enjoyed a boom in the early 20th century as a result of the growth of the meatpacking and oil industries which created paraffin and stearic acid as byproducts. The feedstock for paraffin is slack wax , which is a mixture of oil and wax, a byproduct from the refining of lubricating oil.

The first step in making paraffin wax is to remove the oil de-oiling or de-waxing from the slack wax. The oil is separated by crystallization. Most commonly, the slack wax is heated, mixed with one or more solvents such as a ketone and then cooled. As it cools, wax crystallizes out of the solution, leaving only oil.

This mixture is filtered into two streams: solid wax plus some solvent and liquid oil and solvent. After the solvent is recovered by distillation, the resulting products are called "product wax" or "press wax" and "foots oil". The lower the percentage of oil in the wax, the more refined it is considered semi-refined versus fully refined.

The wax may finally be blended together to give certain desired properties such as melt point and penetration. Paraffin wax is sold in either liquid or solid form. In industrial applications, it is often useful to modify the crystal properties of the paraffin wax, typically by adding branching to the existing carbon backbone chain.

The modification is usually done with additives, such as EVA copolymers , microcrystalline wax , or forms of polyethylene. The branched properties result in a modified paraffin with a higher viscosity, smaller crystalline structure, and modified functional properties. Pure paraffin wax is rarely used for carving original models for casting metal and other materials in the lost wax process , as it is relatively brittle at room temperature and presents the risks of chipping and breakage when worked.

Soft and pliable waxes, like beeswax , may be preferred for such sculpture, but " investment casting waxes," often paraffin-based, are expressly formulated for the purpose. In a histology or pathology laboratory, paraffin wax is used to impregnate tissue prior to sectioning thin samples of tissue. The tissue is then placed in paraffin wax for a number of hours and then set in a mold with wax to cool and solidify; sections are then cut on a microtome.

People can be exposed to paraffin in the workplace by breathing it in, skin contact, and eye contact. From Wikipedia, the free encyclopedia.
