What is Soudal Pro Gaps Light Speed Filler used for? 

Beyond basic hole filling, Light Speed is specifically designed for:

  • Plasterboard Repairs: Filling joint lines, scuffs, and impact damage on internal drywalls.
  • Ceiling Fixes: Because of its ultra-lightweight consistency, it is the ideal “non-slump” filler for overhead repairs.
  • Masonry & Concrete: Patching small chips or cracks in rendered walls, stone, or concrete blocks.
  • Pre-Paint Preparation: Smoothing out imperfections on skirting boards or architraves before the final topcoat.
  • Exterior Maintenance: Repairing cracks in eaves or protected outdoor surfaces before painting.

What are the features and benefits of Soudal Pro Gaps Light Speed Filler?

The primary benefit of Light Speed is its ability to redefine the “prep-to-paint” timeline. By utilising advanced binders and lightweight glass-bubble technology, it offers technical advantages that standard spackling compounds cannot match:

  • Rapid Workflow: Can be sanded in 5 minutes and is paintable in 15 minutes, allowing you to finish a room in a single session.
  • Ultra-Smooth Finish: Engineered for professional paint finishes with zero “mapping” or graininess.
  • Minimal Shrinkage: High-solids, low-density formula ensures the filler stays flush with the substrate, often removing the need for a second coat.
  • Easy Sanding: Requires only a light scuff with fine-grit sandpaper, protecting the surrounding paper on plasterboard from damage.
  • Ready-Mixed Convenience: No messy mixing or water ratios required; apply it straight from the tub for instant repairs.
  • Versatile Application: Suitable for both interior and exterior applications, providing a durable bond to almost any porous surface.
  • Non-Slump Formula: Stays exactly where it is applied, making it perfect for vertical cracks and ceiling holes.
  • Layering Capability: For deeper voids, the quick-dry nature allows for fast layering with only 5–10 minutes between coats.

FAQs

How soon can I sand and paint over Soudal Pro Gaps Light Speed?

Soudal Pro Gaps Light Speed is engineered for rapid turnarounds. You can typically sand the surface in just 5 minutes after application. Once sanded and dusted, the filler is ready for painting in as little as 15 minutes. In very cold or humid conditions, these times may extend slightly.

Does Light Speed filler shrink or crack after it dries?

No. Light Speed is formulated with high-solids technology and lightweight glass bubbles, resulting in minimal shrinkage. Unlike heavier compounds that recede as they lose moisture, Light Speed remains flush with the substrate, usually requiring only one application for standard holes.

Can I use this filler for deep holes in my wall?

Yes, you can use Light Speed for deeper cavities, but we recommend a layered application. For holes deeper than 5mm, apply the filler in stages, allowing approximately 10 minutes of drying time between each layer for a stable, flush finish.

Is Light Speed filler suitable for outdoor use?

Yes, Soudal Pro Gaps Light Speed is suitable for both interior and exterior applications. It provides excellent adhesion to stone, concrete, and exterior plaster. For all exterior repairs, the filler must be painted over once cured to protect it from direct weather exposure.

Do I need to prime the surface before applying Light Speed?

In most cases, no primer is required when applying Light Speed to porous surfaces like plasterboard, brick, or concrete. Simply ensure the area is dry and free of loose dust before you start filling to ensure maximum adhesion.
