Looking to renovate a merbau deck that was done with Sikkens about 5 years ago, can I use Intergrain DWD over the sikkens product?
Hi Keith, DWD won't be compatible with Sikkens straight over the top but if the Sikkens is in sound condition i.e. not peeling etc. you can follow the below method to coat over the top to ensure it will properly adhere. It's a bit of a process but allows you to avoid sanding to change the coating:
1. Intergrain UltraPrep Tannin & Oil Remover
2. Intergrain UltraPrep Timber Cleaner
3. Intergrain UltraPrimer
4. Intergrain DWD
If the Sikkens is peeling off, best to sand it back before coating with something new.
I have a very large decking area that is finished in DWD. A very large Eucalyptus overhangs a large portion of the deck and consequently the dropped eucalyptus oil has stained the DWD black. Other areas of the decking, in the sun, have worn, bare patches.
Q1/ Can the eucalyptus oil stains be removed with any of your products ( even Napisan...?? ) If no,
Q2/ For the sun-worn, bare patches and the oil stained section what is the recommended removal method for the existing DWD prior to recoating using your three step method: sanding with a belt sander, PowerPrep or Intergrain Timber Stripper ... ??
Hi Duncan, we don't have a recommendation for stain removal however if the alternative is to remove the coating I would suggest trying any stain removers you might have first. If there are sections of coating worn back to bare timber and you are planning to re-coat, we recommend to sand the area, clean with UltraPrep Timber Cleaner and then apply. A bit of a process but you'll get great life out of it when it's done properly.
I’ve sanded deck back, used ultra prep timber cleaner and a flood coat of ultra primer and it has dried uneven particularly where brush strokes stop and start. Can I give it another coat to even it out?
This is a terrible web site. All I get is re type your message or resubmit your reply. For god sake I’m waiting for you to reply.
Hi Bazz, good question, it depends on whether it's the coating that has dried unevenly or if the bare timber has absorbed the coating unevenly. If the first coat was absorbed unevenly, you can certainly give it another coat to help even it out, now that the timber has been sealed, the top coats of DWD will apply evenly. If it's the actual film that has been applied that has imperfections in it, we would recommend giving it a light sand then apply a second coat of primer to get the best results.
I’ve already submitted but not sure it went through. Anyway, prepared my deck with deck wash as I have done before. Used this intergrain Ultra Deck Timber Stain Drift Wood. Applied at lunch time and looked great. This morning I’ve gone out to look and it’s all gone a weird mottled effect and looks awful. I’m not sure what has gone wrong overnight. What can be done? Really disappointed. Thanks. John
Hi John, sorry to hear it's not looking right. Is it only the first coat that has gone down? Sometimes the first coat is absorbed unevenly by the timber and it evens out on the 2nd and 3rd coat. I'd suggest giving our technical team a call on 1800 630 285 so they can ask you some follow up questions and help to quickly problem solve. The Intergrain Team
I’ve used Timber deck with driftwood tint. Prepared the deck with a deck wash and applied the timber deck driftwood at 2pm. It dried and looked great. I wake up and this morning it’s now got a sort of mottled effect and looks terrible. Why? What can I do? I’m really disappointed. Thanks. John
Are there test pots available for DWD? I only found 1L, which is a bit pricey for a test. Would like to see the look on my timber prior to committing.
Hi Scott, sorry a 1L is the smallest size for DWD. Many stores will have brush outs which will hopefully help you decide if you like the general look of the coating however I appreciate the colour that it ends up will be specific to your exact timber.
I have numerous deck in the back yard, mostly in the shade. They were built about 12 years ago and professionally painted with Intergrain DWD. Some years ago I thought they needed refreshing and I belt sanded the surface and then applied DWD again. The result is patchy and not great. I now want to ry and fix it and want to ask how to go about it. Gerry
Hi Gerry, if the finish is patchy we would suggest getting the timber back to bare with a sander to start again. Once it's sanded, clean with UltraPrep Timber Cleaner to get the surface ready to accept the new coating. Putting in the proper preparation will give you the long life and beautiful finish you've had in the past. If you'd like some detailed help & advice please give us a call on 1800 630 285 and our team would be happy to assist you including providing a technical data sheet or a spec for your job.

Hi Erin, I did not think sanding the timber down was an option but I did some sanding in the last hour and decided; hey, I can't go anywhere so I will do it. Once I have used Ultraprep Timber Cleaner, how do I go about it? Do I need a primer and do I have to use DWD or can I use some of the other Intergrain product that is available from Bunnings
Hi Gerry, if you are sanding back to bare timber you can use the Timber Cleaner and then use any coating of your choice as the timber will be fresh. If you like DWD and would like to use it again, definitely recommend the primer first to help seal the surface and get the longest life out of your coating. Or, if you've just sanded back the top surface of the coating (not back to bare timber) and it looks nice and even again (no patchiness) you can use the Timber Cleaner and just coat with DWD, no need to use the primer.

Will Dimension 4 seal cedar coated in Weatheroil? Or should it be removed somehow with a prep solution
Can I apply DWD straight onto bare cedar, say three coats? Why is the primer necessary?
my house is clad Western Red Cedar boards and I used DWD about 10 years ago and now wish to repaint. The coating is still in good condition except for patches. Can I just coat with DWD or do I still need to do the 3 phase system on the whole lot...very expensive. This area only gets morning sun
Hi, best to speak with Intergrain Tech support but based on my experience a light sand and couple of coats of DWD will be fine. If you have patches that are water damaged with black stains I'd sand these back, use reviva, primer then DWD
Hi Deb and Kim, to ensure your new coating adheres, give the existing coating a light sand, decontaminate the surface with UltraPrep Timber Cleaner (previously known as Reviva) and then apply maintenance coats of DWD. Cleaning the surface with the oxalic acid cleaner is a really important step to ensure the new coat adheres and you get the longest life out of your top coat. Use of the primer will extend the life of the top coat further. The Intergrain Team
I have some external windows that are in fairly good condition with a previous coating of a stain varnish, is it ok to just scrub down with reviva, prime over the varnish with dimension 4 then coat with DWD or will I have to strip the previous coating off first? (I've tried it on a beam and looks ok just wondering if it will affect performance down the track)
Hi Darren, best to give intergrain a call they are the experts. For best result I’d recommend sanding back and then revive, dimension 4 and dwd. I normally put 4 to 5 coats of dwd to give maximum protection and will last 10 years at least. 1 or 2 coats of anything just doesn’t last especially if it’s direct sun and exposed to rain. It’s a brilliant product but a little bit of work to apply properly.
We oiled our merbau deck on a warm sunny day. Two days later it rained and the deck now has streaky milky stains across sections of the deck - can you pls advise what this is and how it can be fixed?
Can intergrain dwd be applied with a roller
Hi Julie, we recommend that you do not use a roller to apply DWD. Instead apply with a quality brush or spray. If you are coating a horizontal surface like a deck, use the Intergrain DeckBrush or a flat deck applicator.
Hi I have a lot of hardwood doors and windows that have been varnished and are now peeling and going black with weather damage and was wanting to know what would be better to put on them after we sand them to try and remove some staining either Reviva or the vertical timber cleaner?
Hi Ian, it's difficult to say exactly what products to use without knowing a little more about the surface you're dealing with. I'd suggest after sanding the timber back to bare, to clean the timber with Intergrain UltraPrep Timber Cleaner (formerly known as Reviva) before applying a new coating. Please contact us on 1800 630 285 to get more detailed advice on your specific project.
I have moved in to a house that has had dwd coated on all the decking. When it rains or I hose it down it leaves a layer of dirt which I cannot budge. How do I clean this layer of dirt off?
Two coats of dwd after inter grain prep
Each time it rains it goes milky
Now two weeks in Queensland
Will it settle eventually?
Glad to read the comments....Same experience here, 2 hours north of Cairns in the Daintree. We used Intergrain 20 years plus ago, and never had these problems, and I do NOT hint on climate changes.... I am advised to wait one more week for the 3.coat to cure- just lucky we don't have guests right now who would use the steps.....
Can tinted natural stain go over DWD
Hi Paul, we would not usually recommend this system, if you are changing coatings it is recommended to remove the existing coating first. If you'd like more information specific to your project, we would encourage you to contact our technical help & advice team on 1800 630 285. The Intergrain Team
We haveJust laid in a black but deck about four weeks ago.
Im wanting to keep the timber as natural as possible while still protecting the timber.
I was thinking about using the DWD, however I read some reviews that said it was not best for lighter timber.
Could you suggest the best product for use
