Useful for caravan floor repairs
I am a very proud caravan owner and I like to do my own patching up whenever I can. During a recent maintenence, I noticed that on one of the corners, underneath the caravan, the wood has got a bit spongy and I was thinking about repairing it by removing part of the floor and replacing it. I came across wet rot hardener and decided to give it a go, as it would save me a lot of work. Having carefully applied it, I was relly happy to discover that the wood has hardened to the point where I was able to paint over it and no longer worry about it. Recommended.

They leave out the warnings
They leave out the warnings on the listing about the harmful fumes, how you need to call poison control if you breath in the fumes and how it can irritate your eyes, throat so this nasty product is getting binned.contains High concentrations of Acetone

If you need to stabilise rotten wood, and can't replace it, this is the perfect solution
RONSEAL WOOD HARDENER AND FILLER review: I have used both the hardener and filler. The text of this review shows how I used both (I will post same text in each review) I have some decorative woodwork outside the front door which is rotting where water collects at the joints. After removing all the completely rotten material you are left with half rotted wood. If the wood is intact but you can easily push a fingernail into it you should consider using this stuff. It is effectively like glass fibre resin, using the rotten wood as the matrix and the hardener sets the matrix into a hard material. It takes quite a lot of this very runny liquid and you can't hope to brush it into the wood unless you have access to it from above. When I have raked out a hole in some wood I leave it to completely dry out, then I use a blunt hypodermic needle and syringe to inject/squirt the liquid into place. It takes several applications to work, leaving it to dry between applications. Once the wood is hardened, I back fill the hole with plastic wood filler, half a cm layer at a time. Eventually you will have a chunk of plasticised wood and plastic filler that is stronger than the original wood, which you can sand and paint the same as the original wood. This approach is NOT CHEAP, replacing wood would be much cheaper - but it is a a LOT CHEAPER than paying a carpenter to come and replace the wood.

Ich habe den Holzhärter verwendet, um die stark angegriffenen und bereits angegammelten Füße eines alten Schranks meiner Oma zu retten – und das Ergebnis hat mich wirklich überzeugt. Das Holz war weich, bröselig und an einigen Stellen schon deutlich beschädigt. Nach dem Auftragen des Holzhärters hat sich die Struktur spürbar stabilisiert. Das Mittel zieht gut ein, verfestigt das Holz nachhaltig und schafft eine solide Basis für weitere Arbeiten wie Schleifen, Spachteln oder Lackieren. Besonders positiv ist mir aufgefallen, dass sich das Produkt gut verarbeiten lässt. Es lässt sich gezielt auftragen, verläuft ausreichend, ohne komplett unkontrolliert wegzulaufen, und zieht tief ins Holz ein. Nach dem Aushärten war die behandelte Stelle deutlich robuster und wieder belastbar. Natürlich sollte man beachten, dass es sich hier nicht um ein Wundermittel handelt, das komplett zerstörtes Holz ersetzt – aber zur Stabilisierung und Rettung angegriffener Bereiche ist es ideal geeignet. Für mich hat sich der Einsatz absolut gelohnt: Der Schrank konnte erhalten werden und steht jetzt wieder stabil. Wer alte Möbel restaurieren oder zumindest retten möchte, findet hier ein sehr hilfreiches Produkt. Wird bei mir definitiv wieder zum Einsatz kommen.
