Why Roller Filler Works So Well for DIY Beginners
Traditional plastering (such as using multi-finish backing plaster) is highly technical. It requires mixing dry powders to exact water ratios, managing rapid setting times, and using highly coordinated trowel sweeps to get a flat finish before the mix hardens.
If you are currently weighing up whether to tackle your walls yourself or hire professional help, taking a look at our guide comparing DIY vs hiring builders cost and risk can help put your project scope into perspective.
Dalapro Roll Nova completely simplifies this process because it is:
- Pre-mixed and ready to apply: There is no dust, no mixing drills, and no water-ratio guesswork.
- Roller-applied: True to its name, you can roll this filler directly onto the wall using a heavy-duty plaster roller, which naturally keeps the thickness consistent.
- Highly sandable: If your trowel work leaves a few ridges or high spots, the dried material is incredibly soft and easy to hand-sand back to a flat surface.
- Longer open time: It does not set chemically like plaster, meaning you have plenty of time to work the material, adjust your edges, and smooth out imperfections without rushing.
Prepping your walls is a major cosmetic task. Depending on your wider project goals, it is worth understanding the differences between a structural vs cosmetic renovation to prioritize your budget correctly.
Step-by-Step: How to Skim Walls with Dalapro Roll Nova
Here is the exact step-by-step method I used to prep, apply, and finish the walls on my own renovation project:
1. Prepare the Wall Surface
Before opening your tub of filler, the secret to a flawless finish lies in your preparation.
- Scrap away loose paint, peeling wallpaper, and crumbling plaster.
- Wash the wall down with a damp cloth or sponge to remove structural dust and debris that could weaken the bond.
- Fill deep structural holes (greater than 5 mm) with a dedicated deep-fill patching compound first, as Roll Nova is designed for thin skimming rather than deep structural repairs.
- Optional: Apply a high-quality plaster bonding agent (like blue grit or PVA) if your underlying plaster is highly porous or polished.
2. Apply the Filler (The Roller Method)
Although you can scoop Dalapro Roll Nova directly from the tub using a filling knife, it is designed to be rolled.
- Insert a medium-pile or specialized plaster roller sleeve directly into the tub.
- Roll the grey paste onto the wall in vertical strips, working in manageable sections of about 1 m² at a time.
- Ensure an even, generous coat of filler across the section. The grey color is highly practical here: it allows you to easily spot dry patches or uneven areas on the wall.
3. Smooth and Level the Surface
Once a section is rolled on, you must flatten it before it begins to skin over.
- Hold a flexible steel plastering trowel or wide filling spatula at an angle of roughly 20 to 30 degrees against the wall.
- Lightly drag the trowel vertically across the rolled filler to flatten the ridges and push the paste into any underlying hollows.
- Wipe excess buildup off your blade regularly with a clean rag.
- My Real-World Lesson: Some DIY guides recommend using a wide Speedskim rule. However, if your underlying walls are severely warped or uneven, a massive rule can be incredibly awkward to control, often making it harder to get a flat finish. I stopped using mine and went back to a standard hand trowel.
- A Quick Tip on Water: Spraying a very fine mist of water onto the surface can sometimes help glide your blade, but I found that letting the filler dry slightly on the wall actually made it much easier to smooth out without dragging the product off.
4. Let It Dry (Patience is Key)
Because Dalapro Roll Nova is ready-mixed, it relies on evaporation to dry rather than a chemical reaction.
- Allow at least 8 to 12 hours for the coat to dry completely.
- Ensure the room is well-ventilated and kept warm to assist drying.
- A Critical Warning: If you applied a thick coat, the surface may look completely dry and light grey, but it might still be damp underneath. If you begin sanding or painting too early, the damp filler will peel, clog your sandpaper, or ruin your paint finish.
5. Sand and Feather
Sanding is where you turn a rough DIY attempt into a highly polished finish.
- Use a fine 120 to 240 grit sandpaper.
- Use light, circular motions to feather out the edges where your trowel left lines, blending the filled areas seamlessly into the surrounding wall.
- Avoid aggressive sanding: because this filler is incredibly soft, hard sanding can accidentally gouge out new low spots, forcing you to apply another coat.
The Toolkit: Supporting Products I Personally Used
Having the right prep, application, and finishing tools will make your project run infinitely smoother. Here are the exact tools I used to get the job done:
For Stripping Back Old Walls
- Wallpaper Stripper: The Titan TTB926STM electric wallpaper stripper on Screwfix is fantastic for removing stubborn layers quickly.
- Heat Gun: The Wagner Furno 300 electric heat gun on Screwfix works brilliantly on old, stubborn paint layers.
- Heavy-Duty Scraper: Use a rugged long-handled wall scraper on Screwfix to clear off debris without destroying your wrists.
For Applying and Smoothing
- Standard Trowel: The Magnusson plastering trowel on Screwfix is highly balanced and perfect for beginners to hold.
- Speedskim Option: If you want to try a larger skimming tool, the OX Speedskim plastering finishing rule on Screwfix is the industry standard.
For Dustless Sanding
- Hand Sander: The DeWalt XR brushless cordless random orbital sander on Screwfix is excellent for tight corners and high-precision sanding.
- Drywall Sander: To tackle entire walls without exhausting yourself, I highly recommend using the Evolution Power Tools R225DWS Telescopic Dry Wall Sander on Amazon, which features built-in LED lighting to highlight hidden shadows and high spots on your wall.
When to Use Dalapro Roll Nova vs. Traditional Plastering
To keep your project cost-efficient, it is helpful to know when roller filler is the correct choice:
| Use Dalapro Roll Nova When: | Use Traditional Plaster When: |
|---|---|
| Your walls only have light to medium cosmetic damage | You are skim-coating brand new bare plasterboards |
| You want an easy DIY project with zero mixing or cleanup | You need to build up thick layers (over 5 mm deep) |
| You want to work slowly and have time to correct mistakes | You have a tight schedule and need the walls dry in 24 hours |
Plastering is notoriously messy. For an honest look at what you are signing up for, read our guide on how messy a home renovation is before you begin sanding.
If your walls are in terrible shape and need more than a light cosmetic refresh, you might want to look into the average plastering cost per room in the UK to decide if hiring a professional plasterer is a better use of your overall renovation budget.

Using Dalapro Roll Nova on my own walls taught me that you do not need to be a trade professional to achieve high-quality results. However, you do need to follow the rules of prep, patience, and gentle sanding.
