For corners and edges the Mirka® DEOS 3x4 or the Mirka® DEOS 3x5 sanders, as well as the Mirka® DEOS Delta can help you reach even the most difficult spots. In addition, Mirka Handy hand sanding kit is a useful and ergonomic choice when there is no electricity available.
Net plus
Mirka offers a wide range of effective abrasives for different applications. When sanding putty on walls, we recommend choosing the Mirka Abranet® range of products. The ground-breaking Abranet abrasive is fully formed out of mesh, meaning the entire surface area can be used for dust extraction. Abranet is available in different grits and strengths. For hand sanding, Mirka Gold Proflex is a flexible and efficient sandpaper that works perfectly on paint, wood and fillers.
Dust removal
Dust removal is essential when you want to gain a perfect wall sanding result without the mess. And what about the ceiling! When using a hose to combine the efficient sanding tool with a dust extractor, the dust created from sanding can be removed by 99.7%. Dust is placed in the dust bag of the vacuum cleaner instead of remaining in the air and your surroundings. Don’t forget, we recommend using a mask and other protective gear when sanding.
Take care of your health
When you want to perform better and as efficiently as possible, but don't want to inhale dust, Mirka's three-step dust-free solutions are your best friend. When the dust is directed to a dust bag, it doesn't enter your or your customer's lungs.
Decorative Painter, France
Having the right tools for the right sanding application is crucial if you want to exceed expectations in the finish, whether you work on something new or doing renovation work. For Alexandre Lardy, plasterer and decorative painter from France, choosing a dust-free solution from Mirka was an easy choice.
"One thing I’ve really liked and that struck me immediately is the dust extraction aspect.
I have the impression that I’m not sanding at all, so effective is the extraction – I get absolutely no dust."
It's not only great for myself, it's also great for my customers.

Paint fails when applied over uneven, dusty, or poorly repaired surfaces. In construction and renovation projects, this leads to visible defects, weak adhesion, and increased material waste. Uneven walls also demand more coats, raising both cost and completion time.
On commercial sites where speed and quality must align, skipping proper surface prep introduces risk across every phase.
Wall preparation also affects finish consistency across multiple rooms or units. Surfaces with patched areas, joint lines, or rough textures reflect light unevenly after paint. These visual inconsistencies are common on large-scale drywall installations or renovation sites where different substrates meet.
Without uniform sanding and cleaning, even high-quality paint systems will show imperfections under lighting.
Increasing sanding coverage reduces time spent on corrections. According to field data, spending 20% more time on sanding cuts finishing work by 30%. In practical terms, this means fewer return visits to fix surface issues, faster handover, and lower total labor costs per unit. For construction crews managing volume-based timelines, this trade-off ensures better margins and fewer delays.
Start by identifying wall conditions that will affect the paint finish. Look for cracks, peeling paint, joint bulges, water stains, and surface contamination. These issues must be corrected before further steps are taken.
On active job sites, use consistent lighting angles to detect surface irregularities across drywall seams and large wall spans.
Clean the surface using a mild detergent solution and a sponge. Remove oils, handprints, dust, and adhesive residues. In commercial kitchens or industrial interiors, degreasing agents may be necessary to eliminate smoke or oil buildup.
Ensure surfaces dry completely before repair or sanding, especially in moisture-prone zones like restrooms or stairwells.
Fill visible holes, seams, and damaged sections using joint compound or patching materials suitable for the wall type. For renovation projects involving drywall transitions or heavy wear, reinforce seams with paper or mesh tape. Smooth compound application using a wide taping knife prevents buildup and reduces sanding time.
Use fast-set joint compounds when timelines require same-day sanding and priming. Avoid overfilling or uneven layering, as these will show through after painting. Consistency in repair across units or rooms ensures a uniform surface finish after painting, regardless of project size or setting.
Let the compound fully cure. Partial drying leads to bubbling or peeling after paint application, especially on exterior-facing walls or walls near HVAC outlets.
Sanding removes surface irregularities and creates the texture needed for paint to stick properly. For new drywall, smooth out joint compound transitions, tape seams, and any tool marks. For repaints, lightly sand the surface to remove minor defects and dull any sheen that could prevent paint from bonding.
Contractors should avoid sanding too aggressively on drywall edges or over corners, as this can damage the paper layer. Always use a sanding pole or sander with a soft interface to maintain uniform pressure across flat surfaces. In commercial spaces, move in consistent horizontal or vertical patterns to maintain even surface prep across wall sections.
Avoid skipping grits when preparing heavily patched walls. Start with a medium-grade abrasive and work toward a finer one if needed. Spot-check patched areas to ensure they blend smoothly into the surrounding surface. Uneven sanding patterns can result in visible lines or sheen differences after painting.
Inspect surfaces under angled lighting to catch any remaining ridges or bumps before moving forward. Proper sanding at this stage helps reduce paint touch-ups later and ensures a professional-level finish on large surface areas.
Residual dust from sanding can compromise paint adhesion and cause surface defects. Even fine dust left behind will show through paint as a rough texture or uneven coverage. Removing it completely is essential before applying primer.
Start by vacuuming the wall surface using a HEPA-equipped vacuum or a dust extractor system suited for job site use. Focus on baseboards, electrical box edges, and corners where dust tends to settle. Avoid using dry brushes or sweeping, as this just recirculates the particles.
Wipe down the entire surface with a clean, lint-free microfiber cloth. Work in sections to avoid missing spots. If available, use a work light placed at a shallow angle to the wall. This helps detect residual dust or minor sanding imperfections that may need attention.
In larger projects or unit-based renovations, this step ensures consistent quality across multiple rooms. It also supports workplace cleanliness standards and minimizes delays caused by repainting or additional prep.
Primer improves paint adhesion and helps achieve an even finish. It’s necessary on new drywall, bare patches, stained areas, or when applying a lighter color over a dark one. Skipping primer in these cases may result in uneven absorption and reduced durability of the final coat.
Select a primer designed for the wall material. Use drywall primer for gypsum surfaces and masonry primer for concrete or block walls. Stir the primer well and apply with consistent pressure using a roller suited for smooth surfaces. In renovation work, prime all patched or repaired areas, even if the entire wall isn’t being primed.
After the primer dries completely, run a hand over the surface to check for any raised fibers or grit. If needed, lightly sand the surface to remove imperfections. This is especially important for areas where the final finish will be glossy or under strong lighting.
Taking time to prime properly reduces the number of paint coats required and ensures long-term durability, especially critical in commercial interiors where surfaces experience frequent contact or cleaning.

The shorter length and low weight reduce muscle strain, especially in tasks that involve closets, bathrooms, or corridor walls.
For wall prep, LEROS-S offers the same dust-free performance and surface quality as the full-size LEROS but is better suited for tight zones where larger tools cannot operate efficiently. It allows renovation crews to maintain high finish standards throughout the entire space, without switching to manual tools in narrow or awkward areas.
Mirka Dust Extractors are designed to support a fully dust-free sanding process. These units feature high-performance suction, automatic filter cleaning, and low noise output. Select models include HEPA filtration, which captures fine particles and meets air quality standards for indoor construction and renovation environments.
When paired with Mirka tools like DEROS or LEROS, these extractors remove sanding dust at the source. This improves air quality, extends abrasive life, and eliminates the need for secondary cleaning before priming.
In multi-room or high-traffic projects, using a dust extractor ensures cleaner workflows, minimizes delays, and supports consistent prep standards across all surfaces.
Wall preparation affects paint quality, project speed, and long-term performance. Skipping or rushing this step leads to poor coverage, surface flaws, and extra labor. Each part of the process, such as cleaning, repairing, sanding, and dust removal, directly supports better results. For construction and renovation teams, investing in proper prep reduces delays, improves consistency, and lowers rework across jobs. To finish stronger and faster, start with the surface. Prep it right, and every coat that follows will perform better.
