Customer Reviews for Ronseal Wet Rot Wood Hardener 500ml
"Used this some 6 years ago on a scabby garage window sill, so rotten and wet it should really have been replaced. Dug out the rot and soaked the remains in this, sure enough once it had cured it was solid enough to fill."
"Hardens wood like nothing else. Used it many times in various situations. Works well, but if you are working above your head, using a brush will allow the thin liquid to run off (down your arm). Instead I have found spraying using a syringe to be effective, if the wood is very porous you get little or no run off and plenty goes into the wood."
"Quite simply one of (if not) the best wood fillers you can buy and use on the commercial market. I have used this product for over 25 years and trust me it has withstood south facing sun on the exterior of buildings incredibly well where as timber hasn't. This is a fantastic product although it is expensive for a 2 part catalyst reaction substance - hence 3 stars. Reliability gets 4 stars because on exterior woodwork the wood-filler slightly expands over time and can "blow" paint work, otherwise fantastic."
"this product has been used to repair dried out floorboards under bath with poor shower water spill protection having removed all bad wood. It will provide many more years of life in this 1930 house, and will be fitting a screwfix shower screen for future use"
"Used to repair the legs on an arbor, then filled with Ronseal's 2 part wood filler. Arbor now as good as new. The only difficulty with this product is having to clean brushes with cellulose thinners; so I used a cheap brush which I'll eventually bin."
"does what it says on the t**. Needs a few applications but very good. I have some bricks in the house that have become soft enough to gouge out with a fingernail. This product did a nice job of giving the brick a hard weather proof coating. Well impressed"
"Reasonable price, seems to work ok only been down a few weeks but smell from wet wood near a shower leak has gone and wood has lost its sponginess. A lot quicker and easier than cutting out and replacing the wood. Time will tell if it is excellent but no initial problems or complaints."
"wet rot wood preserver soaks in well and cures to give "spongy " timber a solid and sound feel so that you can splice a new piece or fill any gaps or holes created by rot. Have used it on a few occasions now and am never dissapointed."
"Never used a product like this before, but redecorating a wooden conservatory and there was wood going quite soft around the sills. Admittedly I didn't read the instructions properly to start with and merrily slapped it all over anyparts I thought were remotely soft. BIG MISTAKE. Yes it dried hard and seemed to be penetrating well, but then I read any surface needs sanding back again before you paint which is a absolute disaster. Power tools are a no no as its resiny and quickly glues up due to heat from sanding. And its pretty tough to get off by hand esp in difficult to reach places. It seems ridiculous to need to sand it off as soon as you've put it on, but I could also see that as its resin based water based paints wont penetrate/adhere properly. After lots of swearing and sanding the paint went on ok and I hope it will do the trick in terms of reinforcing the wood. But I'll be very grumpy if the paint flakes off in a few months!!!!!"
