Ronseal Wood Filler and Ronseal Wet Rot Hardener for rotten wood 

I’ve applied the wet rot hardener with a hand held spray gun. The type used to spray indoor plants with a mist of water. Works fine and you can spray into really awkward places where you can’t get a brush into.

You’ve done a great DIY there, bundles better than it was before! Thanks for taking the time to do this, I will be buying both for a used garden table just purchased! Thanks.

i used both in the past, the harder defo works. the filler was only half a tin , grrr. set to quickly, very little working time, grrr. but it sanded down easy and left a smooth finish. Yeah. Yes i will buy and use again... thank you, for your video.

Thanks make! That is just what I needed to know so I can do a temporary repair on a wooden door sill! Next year I will be putting in better doors so I only need a quick repair for now! Thanks! :)

LOVELY END PRODUCT...I used BONDO for car repair on a section of wood on my front door. It has worked like a charm (with a bit of work and sanding and painting)

Great video. Telling me all I need to know about this particular product. Thank you!

Wow, this is great.. I did not know they made a wet rot hardener.. Thank you for this video. God bless.

Really helpful vid; liked your additional text comments. Thank you! Oh, and I love the marigolds, mate! 😉

Dear Lord people give him a break. He said this film was just to let us know if the product works & it does. I thank him for this. I’m sure you all were watching it for the same reason as me.

Thanks for this video mate, I think my house has been built exactly the same as yours with the same wood and paint, it's about 20 years old and I need to do something but cannot afford new windows etc, it's just some of the outer frames bits, inside they are ok, I think I'll give this stuff a go, testing on my garage side door first lol! :) Edit: I'd avoid expanding foam for most external things as it will soak up water, but as long as it's then sealed from the outside using another product I see no problem with it! :)

Mix in wood shavings to fill the larger holes as the foam will not last as long as you would like

Great job

Hi there how is it going with the foam after 6 years? Did it prove long lasting?

Do you need to strip all peeling paint off first to bare wood before using this product?

Thankyou! Looks terrific 😀

Brilliant video

Thanks for this video , you did a decent job I think .

Great effort

thank you for this!

Kinda looks like auto body repair putty. Used to use it to repair dorm furniture at the university where I worked.

Can I use this to fill a rotted part of a teak garden bench?

great video. thanks for uploading.

thank you so helpful.

Looks nice!

you can also use car body filler if you got some laying around saves buying the wood filler then lol

Helpful video! Thanks

Well done.

should have done more prep mate,

Thank you :)

Oh dear.

These fillers are never a success long term. suitable timber is best repair.

Who in the Hell does not replace the board?

Nice video but not the neatest of jobs.

This is a foam job not wood filler review. How much do you want to bet you have rot again with all the foam you put lol.

Looks like bondo. Bondo is cheap...

What a bloody cowboy, looks shocking. Stevie wonder would like it

Not a handyman then?

Good job but painting red? After all that work to maintain the natural wood instead of upvc u make it look like red upvc? Really? 😂

This dude is missing part of a finger.

Could of done a better job than that with my eyes closed

Just use car body filler cheaper !

Would love to see some photos of this work two or three years later to see if it's cracked and opened out?

YOUR JUST MISSING A HAT & A HORSE. THEN YOU’LL BE A PROPER COWBOY 🤠🐎

I had some really big holes (much bigger than that) so in the end I put pieces of wood into the holes to save on filler.

Wow. "Tubular Bells". I was educated and terrified at the same time. Thanks for the video!

I would love to see what it looks like now after 7 years .... I have enormous mis - givings, but, who am I .... Uhhh I would though, i'm in usa and Joe Biden is president .... so i have mis givings about everything here right now!!~

Really useful to see it being done by a layperson and not an ‘expert’. Given me confidence to have a go!

you will need cellulose thinners to clean this out 2 pack filler isnt the best option outside i bet this repair lasted 3 years top as a painter by trade i normally use toupret wood repair but timberbuild is the best stuff if you want extra expense will last forever

Splice new timber in ,faster and cheaper !

Great idea, thank you for sharing. I was looking something like that because I have the same situation!!!!!

The lid you took off with screwdriver is to mix in

Very helpful video. Using expanded foam for larger holes has saved me a fortune! Thanks again.

Well, removing all compromised wood should be done first. Prep, to get a good base, is vital in any repair.

Perfect color choice! It stands out and matches at the same time!

Thank you for the video,it was very informative, I have a wooden conservatory with a lot of rot to repair. I read online that you should drill holes in the non rotten wood to help the filler and hardener adhere, did you not find this necessary?

Great , been using this on my windows, my neighbours must think I am mad , my bay windows are 6 windows each, total 12 up and downstairs, I remove each window restore and put back, including bathing the original iron cast hinges in paint stripper and then clear lacquer them. Takes me ages but when it is done looks great , all other neighbours have white plastic windows !

Good honest review, I’ll be trying this on parts of my shed. Thanks for sharing

You need to leave the brush in white spirit for sometime if you want to reuse it but probably no longer a good brush for normal painting anymore.... Using small bits of wood seems better than foam as the filler is designed to adhere to wood not squashy foam for large holes....

Thanks, this was really helpful and informative.

Filler Foams a no no. If it’s that bad cut out the rotten wood and fill with treated wood.

Well done. Infinitely more pleasing than those upvc replacements that seem de rigour these days.saving £ as well. Iain w in glasgow

Try soaking your brush in paint stripper mate see if it sorts brushes like that out

Use car body filter it’s just as good and it’s cheap

I was told by a friend who does professional commercial rehab jobs that it's a well known fact in his circles that there are a lot of types of bugs that LOVE expanding foam insulation. He told me they burrow into it, use it for nests and end up having large colonies or nests. He said he wouldn't use it anywhere insects may have access to it.

good god bodge it and scarper !!!!! just cut out the effected wood and replace with a section of hard wood or tantalised pine , then shape to size , expanded foam will absorb moisture and you will be back to square one al

So your saying nobody will ever know about the bodies under the floor board I love the Amityville horror soundtrack at the end

As for cleaning brushes, I used Hammerite brush cleaner for Hammerite paint and it wouldn't touch it. I also lost a couple of brushes!

If you’ve a home workshop, with a table saw etc., save your sawdust! Especially if you use a dado set! Mix this with 5 minute epoxy to fill the worst of the holes. The sawdust leaves a very rough surface to which these fillers will adhere well. Then apply a finish layer and smooth according to manufacturers recommendation. (The product I used called for using denatured alcohol as a solvent to lightly smooth the finish, with your finger.) Makes sanding a whole lot easier! And a big THANK YOU to the author of this video! Gives me another product to try.

Perhaps wet the putty knife blade before applying the filler. It makes the filler slide off the knife much easier.

The front edge of that sill is angled up, you might want to add a bit more filler underneath to stop water running down to the good wood. Also, avoid using foam filler wherever possible for this sort of thing as it collects water. Good video though! :o)

Amateur at work! The expandable foam should not have been used on this repair as a filler. Too soft to hold its shape and will suck up moisture, leading to more wood rot.

The foam is not sun friendly. Doesn' t llive too much exposed to the direct sunlight. Even being covered by a thin layer of ssomething (except somthing metalic, because it is absolutely opaque). I have a similar problem, but I dont like the idea to aply this foam.

I would recommend car body filler rather than the Ronseal product, if it is being painted over it will be more than man enough for the job and much cheaper, it's a shame you didn't cover the wood hardener in more detail, but on the really bad wood before you scraped it all out.

A very well made video... As I do this sort of work I could point out a couple places that could have been done different to give a better longer lasting finish but really I am impressed with your video making skills and wish I was able to do that.

Wow, I'm impressed with your work and the product.

B+

Good work. Thanks for the info. Very helpful.

I think here in the US things are cheaper. Everything with the word WOOD on it will cost more, just get the Bondo in the red gallon can. Couple of my projects take a whole gallon can or more althouigh I wanted to replace with wood but some cases not practical tearing everything down. If its structural than you do not have a choice. I don't know about using foam. That is at the intersection of filler, foam and wood where there are three expansion and contraction rates. Clean my small brush like yours with lacquer cleaner, an once should do it. BTW excellent job.

05:14 This stuff stinks but does a good job

Good job the filler worked.

I made a table from palet woods can I use hardener to make wood stronger or what would you suggest

Good honest account and very helpful. Thanks.

This was really interesting to watch. Can anyone tell me, what to do in the early stages of wet wood rot? A small area at the bottom of my summer house has started to feel soft as a bucket was placed next to it. The cause of the problem has obviously been removed and I can't see any visible rot as it is beneath the painted surface, but I worry that it may get worse over time? Should I use something like the ronseal wood hardener over the top of the painted wood where I can feel it rotting?

Very useful video. Personally, I have found the Ronseal hardener a little too sticky to penetrate the wood well enough and the filler to go off ( hard) too soon.

I'm building a subwoofer box from mdf, unfortunately due to my own ineptitude and using power tools I have no place to I've ended up with a gap of about 3-4mm x about 4inches and 18mm deep. Will this stuff work for my problem?

Great vid! Realistic result, which is refreshing.

Thank you, this was very informative.

Yes ...Very good I like this vid ,just about to use some of the wood hardener, so this has helped me a great deal thanks for this I think th music to go with it is weird ( in a good way) It's Mike oldfield ,from Tubular bells album .and it was used as as the music for the film The Excorsist. In the 70s , thanks again :-)

As with working on an automobile body. Its best to go light on the filler and layer it in. They do sell a bondo brand wood filler and I know as a fact, it works great! When I worked at an old school, we filled window sills and door jams and sanded them down. Then painted them to match the surrounding wood. Problem is, they tore the whole building down 4 years later.

Can you show us how it's held up over these years?

GLoves! Don't touch white spirit without gloves!

Thanks! Wasn’t even looking for such a solution, but I have such an issue to resolve, door frame rot from the weather over years, and it’s good to know of these products. I would also use the expanding foam and the two products used here…I might use an oscillating cutter (the tiny saw tool, some people call a “multifunction” tool, it’s definitely not the old-school definition of one), to precision-cut away the worst of the rot if it is significant, then either set a new piece of wood in while setting the rot as shown here, and fill to a uniform shape or nearly so, and where possible, patch it with a solid new piece, screwing it into wood that is stable, sinking the screw just enough, cover the sunken screw, and patch amd sand the difference to get a clean corner, or a clean line even if if doesn’t come to a corner, and paint it all up. But every situation is a different, with its own little nuances. A new little piece of wood to help fill major gaps or make a clean corner may or may not fit the situation. Just, for when I could, I’d use all this and patch in a new piece of wood for big gaps, when rot has done serious damage…though lumber prices are high, the product is surely even higher, 😉and I keep nearly all my scrap, it is useful for something eventually. Even today I used some scrap on a project. It’s all I needed. I know the info here is going to help fix 3 exterior door issues for me, so thanks! 🙏🏼😊💕

An excellent demonstration - thank you. I'm having to build up the bottom legs of a number of MDF radiator covers (why are they all 82 cm high?) by about 7 cm. I was thinking of either using MDF or simply creating a former for a 2-part wood filler to create the extra high - I know this can be readily sanded down to a very smooth finish. I will be doing this before assembling them as they come in a flat-pack - any suggestions on the viability of using a former that will be easy to remove from the wood filler once it is dry?

great video

So it's basically a brown car body filler?

Thank you so much for informational video.

Mr botchit

WOW! Great video. I was actually looking for a video of someone using the expanding foam and applying wood filler over it. Wasn't sure if it was just some crazy idea I had that wouldn't work but this looks great! Cant wait to give it a go myself.

never would have thought of using expanding foam. Good tip!
