Review of Dunlop Pro Decor Flexible Acrylic Filler caulk

I recently received a tube of Dunlop Pro Decor Flexible Acrylic Filler to try and review, there has been a bit of a buzz over this product from professional decorators like myself, why, you ask, well because of its claims not to crack and its anti crazing properties. Now unless you use caulk daily like us decorators you may not know the ongoing problem we have when we use caulk and paint over it.

I have written about this problem before on this blog, Tips on using decorator’s caulk, also on Rayfields Interiors, How to use decorators caulk and also Fillers – knowing which one to use and on the Improving Your Property blog, What is decorators caulk / filler.

So when I got this opportunity to try this product and give a review I was very keen to do so, could this really be the end to cracking and crazing filer?

The tubes are filled with a white acrylic filler and come in a 310ml tube, allowing easy application by using a caulking gun.

I have tried the product and here is my review.

My review of Dunlop Pro Decor Flexible Acrylic Filler

On the Dunlop Decorators website it says this about the product:

FLEXIBLE ACRYLIC FILLER™

A high performance gunnable filler which can be used internally and externally for filling skirting boards, window and door frames as well as repairing cracks and damage to walls and ceilings.

  • Paintable in 60 minutes
  • No Crazing
  • Ultra smooth
  • Anti-Crack

I was very keen to test the no crazing and anti-cracking claims.

I tried the acrylic filler on my last two jobs, I have used it around skirting boards and ceilings, and painted over it with different types of paint, including water based primer /undercoat, gloss, satinwood and emulsion. I also noted the drying time and smoothness once dried.

The result

I was pleased to be able to try this acrylic filler and see if it met all of it’s claims, which for me it did. It seemed to dry fast allowing me to paint over it quickly. For the normal troublesome emulsion crazing / cracking issue I can say I didn’t come across any of this issue so was really impressed. Once dry the filler left a smooth surface that didn’t show once pained. I also didn’t see any cracking once it dried, I tried this product in both small and large gaps and had the same results.

In conclusion

I was very please with this acrylic filler, and from a professional decorators point of view the fact it stand up to it’s claims and doesn’t crack or craze like many other brands of decorator caulk, this is something we have been waiting for for years.
Now that I have used this product I will certainly be changing over to use this acrylic filler all the time and will certainly be wanting to try Dunlop Pro Decor’s other fillers such as deep hole filler and fine and lightweight fillers in the future.

    Thank you for doing this. I’m a decorator and the crazing of emulsions has been driving me insane. It IS a serious issue with massive implications (i.e. an awful finish) and yet nothing seems to change. The caulk manufacturers blame the paint and the paint manufacturers blame the caulk.

    I thought I’d found a caulk/filler that didn’t craze but last week I had horrendous results (crazing) with Dulux Trade Flat Matt. Crazing all over after 1 hour of paint application on caulk that had dried overnight.

    Hi, I just wanted to say thank you. This has really helped me out.
    I too was so annoyed at the crazing and cracking after painting the caulk, when complaining to manufacturers they simply said spray it with zinsser cover stain prior to emulsioning, well this would be costly in both time and money.
    I saw an ad for the dunlop acrylic filler but was unsure about trying yet another brand of caulk.
    But after reading this, I am going to find out where I can buy it from, as the continuing crazing and cracking on present caulk has cost me hours on previous jobs trying different methods to get the paint settled.

    Really appreciate this Adrian

    Hi, does anyone know if this product could be rubbed down?

    @John

    No it can not. It is a flexible filler and will rub off rather than rub down, like all caulk.
