HB42 Ultimate Wood Filler Review - the best 2-pack filler on the market

HB42 Ultimate Wood Filler Review

By Mike Gregory


If you’re a regular reader of my reviews, you’ll already know I’m a professional decorator, product geek, and I only really write about the products I think are of note. This time, I thought I’d touch on the HB42 Ultimate wood filler, which I have used regularly for some time now.


This is a resin-based wood filler. You take the required amount from the tin, add the hardener, then apply it to any imperfection on timber. Once dry, simply sand smooth and paint over, simple.


You can buy HB42 Ultimate wood filler from various stockists. I tend to buy mine online, but there are plenty of trade counters who stock it. You can also buy it in different sizes and colours. The beauty of using a resin-based filler, is it will expand and contract with the timber. It is waterproof in 30 minutes, and you can even screw holes in it!! In other words, it behaves just like the timber around it.


Are All Resin Based Fillers the Same?


Right, let’s get onto why I thought it was worth putting pen to paper about the HB42 Ultimate wood filler, and not one of the other options. I have used loads of different resin-based fillers in the past. Some of you may think they’re all the same, but if you’ve tried a few, you’ll know they’re not! The gulf in quality is down to the amount of filler in the product, compared to resin and other components. As a rule, the more fillers that are used, the lower the quality of the overall product.


I’ll go a step further and say it is easy for a manufacturer to produce a great product that costs a lot of money. (Oxera products being a prime example). It is also easy for a manufacturer to produce a cheap, low-quality product. The ultimate task is to produce a low-cost option that will also perform well in the real world. That is where HB42 Ultimate wood filler comes in


HB42 wood filler is one of the only products of its kind to be manufactured without a chemical called Styrene. Styrene is quite a nasty substance which can go on to cause health problems. It will probably go on to be regulated in the coming years.


Instead, HB42 use a co-polymer which is structurally related to ABS plastic. The upshot of this, other than avoiding a nasty substance, is the filler is a lot tougher when set.


My HB42 Ultimate Wood Filler Review


OK, I’m finally going to talk about this filler and explain why I like it so much. HB42 Ultimate wood filler is very smooth to use and doesn’t sag at all, which is unlike any other standard resin-based filler I’ve used to date. This makes it easy to use and shape, and you can cover quite large repairs without issue.


It isn’t grainy either, which again, is unlike most other resin-based wood fillers. This means you can use HB42 to surface fill minor imperfections.


The flexibility is also great!! I have used this filler externally on multiple occasions and it just doesn’t fail over any amount of time. A lot of decorators use car body filler, which just doesn’t last.


And finally, the price!! You can spend big money on Oxera products, then invest in specialist tools and go for extra training, but for most instances, this just isn’t needed. If you want a standard resin-based filler which is dependable and easy to use, go for HB42 Ultimate wood filler. It is the best product of its type on the market!
