Poor preparation leads to uneven coverage, peeling paint, and costly rework. Whether you’re spraying a new build, refurbishment, or commercial space, taking the time to prep walls correctly is essential for achieving a professional result. [![Learn More](https://no-cache.hubspot.com/cta/default/20165488/e2fb2c59-8f95-4014-8c0c-8d51b015c445.png)](https://cta-redirect.hubspot.com/cta/redirect/20165488/e2fb2c59-8f95-4014-8c0c-8d51b015c445) At CES Hire, we’ve spent over 40 years supporting painters and contractors with reliable equipment and expert advice. This guide breaks down the key steps on **how to prep walls for painting** before using a paint spray machine. ## 1. Assess the Wall Condition First Before any preparation begins, take a close look at the surface you’ll be spraying. Check for: - Cracks, dents, or damaged plaster[![cracked concrete wall](https://blog.ces-hire.com/hs-fs/hubfs/cracked-concrete.jpg?width=375&height=125&name=cracked-concrete.jpg)](https://ces-hire.com/) - Damp patches or staining - Flaking or peeling paint - Uneven or glossy surfaces Identifying issues early allows you to fix them properly before spraying, preventing defects from showing through the final coat. [![Airless Paint Sprayers For Hire](https://no-cache.hubspot.com/cta/default/20165488/8c019385-788f-4d1b-885d-a3a0231f98c0.png)](https://cta-redirect.hubspot.com/cta/redirect/20165488/8c019385-788f-4d1b-885d-a3a0231f98c0) ## 2. Repair and Make Good Any imperfections will be highlighted when using a paint spray machine, so repairs are non-negotiable. Best practice includes:[![Repairing wall cracks and holes with filler before paint spraying](https://blog.ces-hire.com/hs-fs/hubfs/reparing%20crack.jpg?width=217&height=259&name=reparing%20crack.jpg)](https://ces-hire.com/) - Filling cracks and holes with suitable filler - Repairing damaged plaster or render - Sanding repairs flush once dry - Removing loose or flaking paint completely Taking care at this stage ensures a smooth, uniform surface ready for spraying. ## 3. Clean the Surface Thoroughly Clean walls are essential for good paint adhesion. Dust, grease, and residue can all affect how paint bonds to the surface. Before spraying, you should: - Brush or vacuum walls to remove dust - Wash down greasy or contaminated areas - Allow surfaces to dry fully This step is especially important in kitchens, commercial units, and refurbishment projects where surfaces may be heavily soiled. [![Airless Paint Sprayers For Sale](https://no-cache.hubspot.com/cta/default/20165488/67e97de8-c28d-449a-8635-293997a67059.png)](https://cta-redirect.hubspot.com/cta/redirect/20165488/67e97de8-c28d-449a-8635-293997a67059) ## 4. Sand for a Consistent Finish Sanding helps create a consistent surface and improves paint adhesion. Key sanding tips:[![Sanding repaired wall surfaces to ensure an even finish before spraying paint](https://blog.ces-hire.com/hs-fs/hubfs/sanding%20wall.png?width=319&height=215&name=sanding%20wall.png)](https://ces-hire.com/) - Lightly sand previously painted walls - De-gloss shiny surfaces - Feather edges around repairs Using the correct grit sandpaper will help avoid scratches while still providing enough key for the paint to bond effectively. ## 5. Protect the Surrounding Area Paint spraying is fast and efficient, but overspray can travel further than expected.[![protective mask tape](https://blog.ces-hire.com/hs-fs/hubfs/protective%20mask%20tape.png?width=202&height=325&name=protective%20mask%20tape.png)](https://ces-hire.com/product-category/consumables/tapes-masking-films/) Before you start spraying: - Mask windows, doors, and fixtures - Use painters tape on edges and trims - Lay protective sheeting or floor coverings Good protection saves time on clean-up and prevents damage to finished areas. [![Paint and Render Protection Bundle, Protecting floors, fixtures, and trims before using a paint spray machine (3)](https://blog.ces-hire.com/hs-fs/hubfs/Paint%20and%20Render%20Protection%20Bundle%20(3).jpg?width=236&height=177&name=Paint%20and%20Render%20Protection%20Bundle%20(3).jpg)](https://ces-hire.com/product/render-and-paint-protection-bundle/?cgkit_search_word=bund) ## 6. Prime Where Necessary Priming is often overlooked, but it plays a crucial role in achieving an even finish. You should apply a primer when: - Painting bare plaster or drywall - Covering repairs or patches - Changing from dark to light colours - Spraying over porous or uneven surfaces A suitable primer helps regulate suction and ensures the topcoat sprays evenly.

Check Your Equipment Setup Wall preparation goes hand-in-hand with correct equipment setup.
