What You'll Learn
Grit depends on the material being painted
The grit of sandpaper used depends on the type of material being painted. For instance, if you're working with wood, a coarser grit sandpaper is more suitable for removing flaws and shaping the material. Finer grits are then used to smooth the surface and can be used for wet sanding, which creates a gritty slurry that aids in achieving an even smoother finish. A final sanding with 150-grit paper is commonly recommended for wood surfaces to leave a slight texture for the paint to grip onto.
When working with metal, the grit selection depends on the condition of the metal surface. If the metal is coated with paint or other substances, a coarser grit is initially needed to remove these layers. Finer grits can then be used to refine the surface and achieve the desired smoothness. For bare metal surfaces, less aggressive grits may be used, depending on the smoothness required.
For surfaces like drywall, a medium grit sandpaper is recommended for smoothing, while a coarse grit is more suitable for refinishing furniture. If you're aiming for a polished finish, finer grits are needed to achieve a sleek look.
It's important to note that the grit selection also depends on the extent of repairs or touch-ups required. Extensive repairs typically call for coarser grits, while touch-ups may only need medium or fine grits. The desired finish, such as a textured or polished look, will also influence the grit choice.

Sanding between coats is generally recommended
When sanding between coats of Benjamin Moore Advance, it is essential to use a fine grit sandpaper. The recommended grit is typically between 320 and 400, as this will provide a light sanding without causing damage to the previous coat of paint. The higher the grit number, the finer the sandpaper, creating a smoother surface for the next coat. It is also important to use a high-quality sandpaper designed for wet sanding, which will reduce the risk of leaving scratches or marks on the surface.
Sanding between coats helps to create a smooth and even finish. By lightly sanding the surface, you can remove any imperfections, such as brush strokes, runs, or bumps, that may have occurred during the previous coat's application. This step ensures that each subsequent layer adheres properly and creates a uniform appearance. It is crucial to sand in the direction of the wood grain, if applicable, to achieve the smoothest possible finish.
Additionally, sanding between coats promotes better adhesion. Benjamin Moore Advance is a water-based paint, and light sanding creates a surface that the next coat can effectively adhere to. This step helps to ensure that the paint layers bond strongly and reduces the risk of peeling or flaking over time. It is essential to remove any dust particles after sanding with a tack cloth or a damp cloth to ensure a clean surface for the next coat.
It is also worth noting that while sanding between coats is recommended, it is crucial not to over-sand. Over-sanding can cut through the layers of paint, exposing the previous coat or even the bare surface. This can lead to an uneven finish and require additional coats to achieve the desired coverage. A light sanding with the appropriate grit sandpaper should be sufficient to provide a proper surface for the next coat of paint.
Finally, proper preparation is key to achieving the best results. Before applying the first coat of Benjamin Moore Advance, it is essential to start with a clean and lightly sanded surface. This initial sanding step will help the paint adhere properly and create a smooth base. Then, by following the recommended process of light sanding between coats, you will achieve a professional and durable finish. Remember to allow sufficient drying time between coats, typically 16 hours, for optimal results.

Sanding before priming is essential for some materials
Benjamin Moore Advance Paint is an alkyd paint that does not require a top coat. It can be used for painting furniture and kitchen cabinets. While the paint itself does not require sanding, the surface to be painted may need to be sanded and primed before painting.
The type of grit sandpaper you use will depend on the material you are preparing to prime. For wood, start with coarse sandpaper, such as 80-grit, and gradually increase in fineness to 150-grit or 220-grit. For softer surfaces, such as plastic, start with a higher grit size, such as 120, to avoid excessive scratching. For metal, start with 60-grit paper if you need to sand down below rust or repair deep scars. Then increase the grit to 120 and finally to 320 before applying primer. For drywall, 100-grit sandpaper will do, and 120 at the most. For furniture, use 320-grit.
Sanding before priming is also important for removing fibres from rollers or other debris that may end up in the finish. It will also help to smooth down the grain of the wood, which can rise due to the paint interacting with the wood and swelling the fibres. This can cause a raised grain appearance, which can result in a duller finish. Sanding after priming will also help to smooth the surface and eliminate brush marks, dents, and leftover bumps.

Sanding tools vary depending on the material
Benjamin Moore Advance paint is an alkyd paint that doesn't require a topcoat. When using this paint, you don't need to sand the surface after applying it. However, if you're working with a darker colour, you should use a primer first. After priming, use 220-grit sandpaper or a sanding block to lightly sand all surfaces, ensuring you don't remove the primer coat.
Hand sanders are manual tools that require physical effort and are ideal for small, detailed work where precision is key. They are often used for finishing touches and work well on surfaces that need a light touch. Orbital sanders, on the other hand, are electric tools that move in small circles or orbits, making them versatile and suitable for a wide range of projects. They are perfect for smoothing rough surfaces and preparing surfaces for painting, and their random motion helps avoid leaving swirl marks. Belt sanders are designed for rapid material removal from large, flat surfaces and are often used in the initial stages of sanding to remove old finishes. Random orbit sanders combine the speed of a belt sander with the finish quality of an orbital sander, making them versatile for both coarse and fine sanding tasks.
Detail sanders are designed for sanding in tight corners and intricate spaces, while dustless sanders are powered sanders with integrated dust collection systems, making them ideal for interior construction where dust control is important. Additionally, the pressure applied during sanding impacts the speed and quality of the process. Applying too much pressure can slow down the process, increase tool wear and tear, and cause issues on the finished surface.

Sanding direction should be with the grain
Benjamin Moore Advance Paint is an alkyd paint that can be used on kitchen cabinets and furniture. It does not require a topcoat and can be applied between 50°F and 90°F. Before painting, the surface should be prepared by removing old hardware, filling in old hardware holes, and cleaning with a grease remover. For any scratches, sand them down with medium-grit sandpaper (100-150 grit) and fill them with wood filler. After the filler dries, sand the areas again with fine-grit sandpaper (220 grit) and wipe away the dust with a damp cloth.
Sanding direction should always be with the grain of the wood. Sanding with the grain will result in a nicer finish as the scratches will be less visible and will blend in better with the wood grain. Sanding against the grain can leave visible marks and deeper gouges in the wood. It is also important to use increasingly finer grits of sandpaper as you sand to achieve a smooth finish. While orbital sanders can leave swirls, these can be minimised by using a block sander or by hand-sanding the final pass with the grain.
