In a perfect world, walls would be flat, corners would be square, and scribing timber would be a quick job. But anyone who lives in a Victorian terrace in York knows that is rarely the case. When fitting bespoke alcove shelving or skirting boards, leaving a seamless finish often comes down to one thing: a decent decorators caulk.

Many homeowners make the mistake of buying the cheapest filler they find, only to watch it crack or craze within weeks. Joinery involves timber that expands and contracts, and the masonry in older properties moves too. You need a caulk that flexes without breaking the paint seal.

In this review, I'm looking at three options I've come across on site: a reliable budget tube for quick touch-ups, a complete kit for those starting from scratch, and a bulk option from a trade-trusted brand that solves the problem of running dry halfway through a large project.

Specs vs. The Real World

The Spec: "Paintable in 1 Hour"

The Theory

"Manufacturers claim you can paint over the caulk almost immediately to speed up the job."

The Reality

In York's often damp or cooler older houses, one hour is rarely enough. If you paint too soon, the paint will 'craze' (crack) as the caulk shrinks underneath. I always recommend leaving it overnight if time allows.

The Spec: "Non-Cracking / Flexible"

The Theory

"The product claims to withstand all movement without cracking."

The Reality

While modern acrylics are flexible, nothing performs miracles on a 10mm gap. For gaps larger than 4-5mm, you should be scribing the timber closer to the wall or using a backing rod, not just relying on caulk.

My Top 3 Recommendations

Three options to cover different needs and budgets

EVO-STIK Decorators Caulk White - 280ml

Budget Pick
EVO-STIK Decorators Caulk White - 280ml

EVO-STIK

For a simple, single tube to finish off a small job like a set of shelves or a new skirting board, this EVO-STIK option is reliable and affordable. It tools smoothly and is widely available, making it a staple in many toolboxes.

Price£4.42 (at time of writing)
BrandEVO-STIK
Dry TimeApprox. 1 hour (conditions dependent)
ApplicationInterior gaps around skirting & door frames
The Good
  • Very affordable for small repairs
  • Easy to smooth down with a wet finger or tool
  • Sanding capability helps achieve a smoother finish
The Bad
  • High shrinkage rate if applied too thickly
  • Truly needs longer than 1 hour to cure in cold houses

Installer Tip:

Cut the nozzle at a 45-degree angle, but keep the hole relatively small. It's easier to add a second bead than to clean up a messy, overflowing one. Perfect for shrinking the gap between a fitted alcove shelf and a wonky breast wall.

Decorators Caulk White Set - Bundle With Sealant Gun & Tools

Quality Pick
Decorators Caulk White Set - Bundle With Sealant Gun & Tools

Swiflee and Co

If you don't already have a skeleton gun in the van (or shed), this bundle is the quality choice. It pairs Soudal (a trade favourite brand) with the necessary application tools, ensuring you can get a professional finish without buying everything separately.

Price£16.99 (at time of writing)
Contents2x Soudal Caulk, 1x Gun, Tool Set
BrandSwiflee / Soudal
Best ForComplete beginners or fresh setups
The Good
  • Includes a sturdy steel caulking gun
  • Profiling tools help achieve a perfect radius on internal corners
  • Soudal caulk is generally higher quality than basic DIY store brands
The Bad
  • More expensive upfront if you already own a gun
  • Profiling tools require a bit of practice to use effectively

Installer Tip:

Use the smoothing tools included in this kit rather than your finger. The acid in your sweat can sometimes affect the paint finish later on, and the tools give a consistent profile that looks much sharper on fitted furniture.

When caulking long runs of skirting or shelving, keep a damp rag or sponge handy. Wipe the nozzle clean after every run to prevent dried crud from ruining your next bead. This bulk pack is perfect for doing the whole living room in one go.

Frequently Asked Questions

Why does my caulk crack after painting?
This is usually because the paint was applied before the caulk had fully cured, or the gap was too large for caulk alone. In York's moisture-prone terraces, caulk can take up to 24 hours to fully shrink back. If you paint too soon, the paint dries rigid while the caulk is still moving, causing 'crazing'.
Can I use decorators caulk as a glue?
No. Caulk is a filler, not an adhesive. It has very little structural strength. For fixing skirting boards or shelves, you need a high-grab adhesive (like Gripfill or Pinkgrip) or mechanical fixings. Caulk is purely cosmetic to hide the gap.
How do I get a neat finish on alcove shelves?
The secret is sparing application. Cut the nozzle small. Apply a thin bead. Smooth it once with a wet finger or profiling tool in one continuous motion. Don't keep playing with it, or you'll make a mess. If the gap is huge, scribe the timber first—don't rely on caulk to hide bad carpentry.
Do I need to sand decorators caulk?
Some modern caulks (like the EVO-STIK reviewed here) claim to be sandable, but in my experience, it's difficult to sand rubbery acrylic without it rolling up. It is much better to get the finish smooth while it is wet. If you need a perfectly flat, invisible joint that can be sanded glass-smooth, use a two-part wood filler instead of caulk.
What is the difference between caulk and silicone?
This is crucial: Caulk is paintable; silicone is not. Use caulk for skirting, architraves, and fitted furniture that will be painted. Use silicone for bathrooms and kitchens where you need a waterproof seal that won't be painted over. Never use silicone on your alcove shelves if you plan to paint them!
