  • Due to the waxy surface, sanding with normal sandpaper does not work, as it will clog up immediately. Amine redness is not a problem in itself: it is the effect of it that is the problem. If you continue to work without removing this layer, it will prevent lacquers, other epoxy coatings, and other substances from bonding effectively and ensuring adhesion. The surface should therefore definitely be cleaned. Here is a great method for removing amine blush from your resin projects: - Source: Internet
  • Wet sanding resin would be significantly more difficult if you were to use traditional sandpaper. Normal sandpaper would become soggy and fall apart with extended exposure to water. As such, if you are going to wet sand epoxy, we suggest using waterproof sandpaper. Waterproof sandpaper is made from a closed layer of silicon carbide that resists the effects of water. - Source: Internet
  • When sanding epoxy resin, you’re going to want to do it either by hand with a sanding block, sanding paper, or with an orbital sander. If you’re working with a larger workpiece, the orbital sander might be the better choice considering the amount of elbow grease you’re about to sink into this process. We do not recommend using a belt sander as it will chew up your workpiece. - Source: Internet
  • First things first, put on a dust mask. Sanding produces resin dust which can be quite hazardous when inhaled. Make sure that resin is completely dried before sanding. - Source: Internet
  • During curing, especially at fluctuating temperatures, a slightly sticky, waxy layer may form on the surface. Its appearance changes depending on the moisture content of the air, but it is usually more noticeable in cool, humid conditions. It may be difficult to see at all, or it may appear as a thin, greasy, or dull layer. However, this so-called amine redness can be removed and underneath it, the epoxy resin should be intact. - Source: Internet
  • What is the best polishing compound for resin? This is a bit of a tricky question to answer considering that most polishing compounds, whether they have been specifically designed for use with resin or not, tend to do a pretty good job. This being said, using an epoxy resin polish will do an objectively better job, create less residue, and produce a superior sheen finish. We think that this product nails down all of these characteristics and even a bit more. - Source: Internet
  • Wet sanding is also easy to do. All you do is get the surface wet and sand. You can also use waterproof hand-grade sandpaper to smooth down any rough spots. - Source: Internet
  • We always recommend that you sand epoxy resin wet with waterproof sandpaper. Wet sanding is by far the best way to remove any uneven areas and it reduces the clogging of your sandpaper by the resin dust particles.

  • Use a paper towel to dry your workpiece frequently during wet sanding. Dry sanding can produce heat. So, make sure you take breaks in between to ensure that high temperature doesn’t cause the resin to melt. - Source: Internet
  • Epoxy resin has many different uses in the construction industry. One of the most common uses for epoxy resin is as a coating or sealant. Once the epoxy resin coats or seals the surface, it will be difficult for glue, adhesive, and other substances to stick to because of its high rigidity and strength. - Source: Internet
  • Thankfully, wet sanding reduces the amount of dust produced during the process. Moreover, water collects the dust produced. This helps you to accurately ascertain your progress rate. - Source: Internet
  • Once you’ve settled on which sanding method you’d like to go with, pick a grit anywhere between 120 to 1000 and start sanding. One of the best ways to go about sanding resin is by working in a circular motion, this will ensure that no lines or accidental recesses are created during the sanding process. Once you’re happy with your sanding job, ensure that your surface is flat before moving on to the next step in the process. - Source: Internet
  • You should avoid using a dry paper or steel-grade abrasive. When using wet sandpaper, use an extra heavy grade of 150-grit or higher. Epoxy resin is a material that is often used in a variety of different applications. - Source: Internet
  • The single most important aspect with sanding and polishing is to be consistent and systematic in the chosen approach. Without the systematic and consistent method, it is easy to miss steps and undo all the hard work. Often it is only later in the sanding and polishing process that the shortfalls show through so using a good method from the start will save time later on. - Source: Internet
  • When wet sanding the idea is to use progressively finer grits of sandpaper until the grit that you’re using is so fine that it leaves behind virtually no evidence of sanding. You could start with 400 grit, then move to 600 grit, then to 800 grit, and then eventually to 1000 grit. Wet sanding is usually reserved for larger resin surfaces as it reduces the amount of dust produced in the sanding process, or at the very least ensures that it doesn’t become airborne. - Source: Internet
  • Wondering how to polish epoxy resin? The process of polishing epoxy resin is pretty much the same one you would follow when polishing any other surface, and it even uses similar (if not the exact same) polishing products that you would use when polishing things like wood and metal. This being said, let’s have a look at what you need to do to ensure that you get the best finish possible when polishing your epoxy resin workpiece. Here are some of the things you will need: - Source: Internet
  • To get professional results, it’s always good to gather the necessary supplies before you do any task. The same case applies when you want to sand your resin crafts. But what are some of these tools? Here they are; - Source: Internet
  • Let’s assume that you’re sanding from left to right. Once you see the edges turn white, stop sanding and make your resin wet. Use a paper towel to dry it partially. - Source: Internet
  • Step-1: Arrange tools and materials for dry sanding epoxy Before starting epoxy sanding resin, you should collect all the required equipment. You need sandpaper, an electric sander or battery-operated sander, breathing protection, a couple of gloves, a pair of glasses, and a rag for dry epoxy sand. A random orbital sander is the best option for removing epoxy resin. With its high-speed and dustless qualities, this tool can work with little or no mess on any surface (even polyester). By using different orbits during your cycle as needed you will get perfect results every time! - Source: Internet
  • The compound will contain abrasives that will work to smooth out the surface of the resin. The polishing process may need to be repeated several times in order to achieve the desired results. After the resin has been polished, it should have a smooth and shiny surface. - Source: Internet
  • There are two essential things to note when dry sanding. First, dry sanding epoxy resin produces more dust, so a face mask is required to prevent inhalation. A mask should always be worn when sanding resin since the particles can be toxic and carcinogenic if inhaled. The second consideration is the heat buildup from dry sanding. This heat can actually dissolve the resin, causing a cloudy finish that is difficult to fix. - Source: Internet
  • You just need to get your hands on the required sandpaper and sand. Wet sanding includes pouring water on the surface and sanding with waterproof sandpaper. As you guessed, dry sanding needs no water or waterproof sandpaper. - Source: Internet
  • What is wet sanding? Well, it’s pretty much exactly what it sounds like. It involves using water and sanding paper graded for use on wet surfaces to prepare your resin workpieces. All that you need to do is ensure that your workpiece or sandpaper is wet and ensure that you follow the same process we mentioned previously. - Source: Internet
  • When working with casting resin that is greatly affected by high temperatures, you should definitely go for wet sanding (dry sanding is a big NO in this case). This is because dry sanding produces a lot of heat which can cause the resin to melt. Wet sanding makes use of water as a lubricant which makes it less abrasive. This property of wet sanding greatly adds to the final finish of resin making it smooth and shiny. - Source: Internet
  • To prepare the surface for subsequent epoxy coats or painting, wipe the dry surface with a paper towel to loosen any remaining debris and then sweep it with a bench brush. Don’t use rags—they may contaminate the surface. Follow with an electrostatic dust cloth, such as a Pledge Grab-it®. We use a tack cloth prior to painting, but not for subsequent epoxy coats because the tack cloth is resinous saturated cheesecloth which can contaminate the substrate and interfere with epoxy adhesion. - Source: Internet
  • Wet sanding can make a mess. All the cut debris in the solution with water ends up on the floor. This is difficult to sweep up when dry. But the advantage, as mentioned before, is that wet sanding produces no dust. - Source: Internet
  • If you have a large divot in your epoxy, then you’ll want to fill it in before beginning the second coat. Thoroughly mix a new bit of epoxy, and only cover that spot. Use something self-leveling, like this epoxy, so that you can spread properly and even out the surface! You can also utilize a trowel to help spread the epoxy across the project. Some projects are more porous than others and may need help spreading the epoxy effectively. - Source: Internet
  • The technique is pretty much identical regardless of the grit used and should remain consistent throughout. The only real variable is the starting grit used which is determined by how rough the surface of the resin is. Rough surfaces or freshly machined surfaces will need to start very coarse at a 120 grit level to remove the machining marks, however minor scratches or surface defects will only need a starting grit of 800 grit. - Source: Internet
  • I use a hard rubber sanding block like the one in the photo to hold the paper when smoothing and abrading most surfaces. A curved or soft pad may be necessary on curved surfaces, but you can wet sand without a block or pad by simply folding the cloth to fit your hand and dipping the paper in water. On heavily irregular or textured surfaces such as a sculpture, the waterproof paper won’t contour enough, so use an abrasive pad like 3M Scotch Brite® with water. - Source: Internet
  • Make sure that resin is completely dried before sanding. Wet sanding can get quite messy. So, if you opt for that, ensure that your workspace is covered properly with a newspaper or tarpaulin. - Source: Internet
  • Epoxy ripples can form when the epoxy resin hardens unevenly. Luckily, sanding will enable you to fix this problem. But first, let the epoxy fully cure. Once that happens, lightly sand the surfaces with fine-grit wet sandpaper. Lastly, wipe down the items to remove any dust and debris. - Source: Internet
  • After turning on the sand, place its bottom on the rough surface, then pull the trigger. You need to be very cautious though since sanders tend to vibrate a lot. For that reason, we suggest that you start pulling the trigger slowly. Also, avoid applying too much weight on your sander to avoid over-sanding the resin surface. - Source: Internet
  • For a finer and smooth finish, you should gradually go from lower to higher grit sandpapers. Low grit sandpapers are coarser, while higher ones are finer and are used later for a smooth finish. Start sanding your resin with 150 grit sandpaper and gradually move towards higher ones. It is preferred to start with this grit size because a lower grit size can put deep scratches on the surface. - Source: Internet
    1. Make use of a hard rubber sanding block. As stated above, using an electric sander is dangerous if you are wet sanding. Also, wear eye and mask protection. Switch to a curved sanding block when you need to sand curved surfaces. - Source: Internet
  • Dry sanding can produce heat. So, make sure you take breaks in between to ensure that high temperature doesn’t cause the resin to melt. Go from the lowest grit size of sandpaper to the highest grit size gradually. - Source: Internet
  • Dry sanding is a better option when you are sanding a large area and when time and effort are your prime concerns. While dry sanding, there is going to be a lot of dust involved. So, we strongly suggest you wear a respiratory mask while you are dry sanding. As we have already mentioned before, you must work in an open area or at least in a well-ventilated room. - Source: Internet
  • The other benefit of wet sanding is that it prevents the abrasive paper from getting clogged. On top of that, this approach produces less heat. These factors make the sandpaper last longer and protect the surface finish. - Source: Internet
  • Dry sanding tends to produce a lot of dust. This dust covers your pieces, making it difficult to determine your progress. Worst of all, dust from epoxy resin can have harmful effects on your health. So, always wear a breathing mask for safety purposes. - Source: Internet
  • Before you start the process, apply water to your resin objects. To do this, put cold water in a spray bottle. Alternatively, you can get a bucket or bowl of water readily available. - Source: Internet
  • Considering its versatility, epoxy resin can adhere to most surfaces out there. Although this is a great thing, some of these materials are susceptible to water damage. A good example of a moisture-susceptible material is wood. - Source: Internet
  • Orbital sanders are very aggressive in their mode and should be used carefully with attention to the type of disc, pressure, and even movements. Dry sanding epoxy resin with an orbital sander risks dissolving the material and should be carefully performed. Wet sanding is not common with an orbital sander but can be accomplished. - Source: Internet
  • When it comes to sanding epoxy resin, there are a few things that you should be aware of. Epoxy resin can be tricky and a little risky to sand, but with the right tips and tricks, you will be able to sand epoxy safely. The main difficulty when sanding resin lies in the hardness of the surface. The main safety concern when sanding epoxy lies in the toxicity of the particles. - Source: Internet
  • But, there are several occasions where dry sanding proves to be more beneficial. For instance, dry sanding works best on materials that are partially made of wood or other similar materials that are moisture sensitive. If you wet sand wooden materials, it would cause the wood to swell up and may also cause hideous stains on the surface. - Source: Internet
  • The dust produced when sanding resin can cause serious health problems if inhaled. The small resin particles are carcinogenic and can damage your lungs, so it is always recommended that you wear some sort of mask when you sand epoxy.

  • In most cases, wet sanding is preferred as it’s considered to provide more effective results. This, however, doesn’t mean that you can’t dry sand your crafts. Indeed, this technique is more suitable in certain circumstances. It’s very effective when you’re working with moisture-sensitive materials. - Source: Internet
  • In this part, we are going to take a look at how you can efficiently perform the process of wet sanding epoxy resin. Wet sanding is mainly performed by hand. We strongly advise you against using electrical equipment as it can give out electric shock because of the water used. You can consider using an air-power sander to work on large surfaces. - Source: Internet
  • Using a spray bottle, spray some water on your resin pieces. If the water is in a bucket, pour some water on the items with a bowl. Alternatively, you can soak the sandpaper in the water and use it to sand the items. - Source: Internet
  • All room temperature cure amine-base hardening epoxies are susceptible to amine blush to some degree. This amine blush is soft and can be a little greasy or gooey; it doesn’t cut, but clogs or balls up so you can go through a lot of paper with little progress. (When epoxy balls up it’s an indicator that the epoxy isn’t fully cured.) Amine blush should be removed to prevent interference with subsequent coats of epoxy, paint, or varnish. - Source: Internet
  • When wood comes into contact with water, it tends to swell. For this reason, you should protect wooden pieces from water. One way to accomplish this is to dry sand instead wet sanding. - Source: Internet
  • Remember, you have an array of 400 to 1000-grit sandpaper. But which one do you use? Simple! Start with the 400-grit sandpaper and work your way up to the 1000-grit sandpaper. Make sure you cover the entire surface before you move to the next grit. Also, take note of the spot you’ve already sanded to avoid over-sanding. - Source: Internet
  • Use a paper towel or a clean rag to clean the epoxy surface. Luckily, this step will be quite simple since you’re wet sanding. Once you’ve achieved the desired smoothness level, the process is complete. However, if the surface doesn’t have the perfect smoothness, continue the process. Afterward, clean the items again and leave them to dry immediately. - Source: Internet

As a result, there is virtually no secondary surface scratching with wet sanding, and the sandpaper lasts longer due to less clogging of residue. - Source: Internet
  • Waterproof sandpaper is usually a closed coat, silicon carbide. It’s available from most automotive paint and supply stores. Grits from 60 to 1000 are available, although you should only need 60 to 80 grit for initial abrasion, and 180 to 220 grit or maybe 320 for final sanding prior to priming or varnish. If your cured epoxy has runs and irregularities, I suggest starting with 60 or 80 grit sandpaper. Work your way up until you get the degree of finish you’re after. - Source: Internet
  • While we typically do not recommend it, you absolutely can dry sand resin, and there are a few instances where it is your best option. When you are working with a combination of epoxy and wood, wet sanding can cause the wood to swell which is not ideal. On the whole, it is not recommended to dry sand. The heat caused by dry sanding with an orbital sander can actually dissolve the epoxy resin. The dissolved resin will become matt, and it will take a great deal of effort to restore the luster. - Source: Internet
  • If the irritation persists, you may want to consult a doctor or dermatologist for further treatment. Next, you can use a solvent-based cleaner to remove the resin. This can be as simple as using water, or you can use denatured alcohol to help neutralize the resin. - Source: Internet
