help needed oil based disaster!

[hollie1978]

Hi all! This is going to make me sound really dumb ...but here goes.

We have some kwila vertical privacy screens at the front of the house. They had very old water based stain on them that was chipping away. I sanded it back as much as I could with 80 grit sandpaper- scrubbed and scrubbed until no more would come off - some of the paint just wouldn't budge, but I thought it would be ok.

So I then coated it with Sikkens in the Teak stain. (it's oil based) and there are patches everywhere . Some of it looks blackish and other parts look red.

So now i have to get the Sikkens off and re-scrub the screen to get the remaining water based off

The question is....how? Is there a liquid solvent I can use to get the oil based off? Then re-sand the water based and hope it comes off?

I don't know!

Firstly welcome to the forum.

I have removed paint from metal surface using paint stripper. The brand that I used was by Diggers and can be purchased from Bunnings. I would suggest that you take a look at the can to ensure that you can use this to remove the oil based stain.

Otherwise you will be sanding again. One thing I might mention sand paper are not all the same quality and do clog up quite quickly. Also sand throught the grits that way you will get a better surface to start with.

Lots of Turpentine, packet of those Nylon, ( kitchen ), scourers, and heaps of good ol' fashioned," Elbow Grease," along with a few choice descriptive words should solve the problem. Haven't been that dumb myself,- but know someone who did, and I got the horrid job of cleaning up their stuff-up, then recoating everything. From memory there were four window frames, and a complete front door, frame, & all. To make things worse, the culprit was a Professional Master Builder, who was doing a restoration contract job on an older style home some years ago in this area, and to top it off,- you can't do things like that in a side street,- it has to be in the main street, where everyone can see your monumental stuff-up. ( Murphy's Law ????? )
*** In younger days have worked with various builders, handymen, & painters,- AND believe me I have seen some absolute," Clangers " at times, which would make your problem small in comparison.

Ok great thanks - does the turps get the remnants of the water based off too? How should I get that off?

thanks

Now it gets interesting. Judging by what you have typed about your problem, it sounds like you are refering to Acrylic Paint which sits on the wood surface, and over the years has gradually cracked, & peeled away to become all," Yukky," and horrible-looking, as ordinary Water-based stain simply soaks into the timber surface, and over time simply fades away,- also water-based woodstains are not really meant for outdoor useage. That sound more like what your problem is to you ?

IF it is Acrylic House Paint / Acrylic Timber Finish residue you are dealing with,- Methylated Spirits will soften and disolve Acrylic House Paints / Acrylic Timber Finish,- Discovered THAT by accident Followed by scrubbing with a Nylon Scourer pad and hot water with double-strength/ triple-strength dishwashing detergent disolved in it, then hose off and allow to dry. To finish, sand off any remaining sections of the water-based product,- Begin with 80 grit, and work through to 120 grit; 180 grit, etc. Providing the timber surface is flat, use a sanding block, and if wide enough use an orbital power sander, ( if you have one ) to speed up the sanding process, and save aching hands, & arms.
Hope this info helps.
IF you are still having probs,- can you send me a photo of the problem, or even place a pic on this thread which will, ( or should ), help heaps.
