I was volunteered to help with a small remodeling project in my family. This house has 6 panel oak doors and oak trim that I installed 10 -12 years ago. They are custom stained to the Honey Oak/provincial style that was popular then. She did not change out the closet bi-fold doors until now. Back then, I stained everything and brushed on a oil based poly then the final coats were a wipe on poly.

My question is I now spray a water based poly….knowing that oil based is “warmer” in tone than water base…do you think that it will be noticable difference that I use water base this time? I really like the ease of the clean up of water and do not want to use an oil base unless I have to!

Thanks in advance…..I will be out of town most of next week so I will not respond until Thursday or so, but I need to start upon my return.

Yes, you will probably see the difference (and so will she…).

Fix the problem by using a stain or dye to correct the color under the poly so the finished product will match the existing doors. Experiment with scraps until you get it right.

Good Luck!

Trans Tint liquid dyes can be added to water base poly, I have done it to give it the warm oil look, it was an experiment on a shop project, cant remember if I added yellow, or one of the maples, and I am not at home for a few weeks to look in my finish note book.

Moke, take a look at Target’s Emtech coatings. The WR4000 is a linseed oil emulsion that you can use as a base to give the oil look you achieved originally. It is very user friendly. If you have questions, call Jeff Weiss at Target Coatings, he is a great guy and a wonderful resource. HTH

Agree with using Target’s WR4000 stain base if you want a WB dye, and highly recommend their 9000 WB poly. As for warming up a WB poly, use Transtint Honey Amber to get the OB poly look. You will have to test with your WB poly to find the right mix. I tested by getting some small clear plastic cups and putting in OB poly and let cure, then different intensities of HA TT in WB poly to see what the cured finishes looked like.

They always suggest sneaking up on it, I would a piece of wood, the same as you are working on and start sampling. I think with the Trans tint the mix for the color is 1oz per quart, it you go to there sight they have it and a color chart.

Remember with a colored finish, it is the last coat that counts.

Moke, I use 1ml/ounce ( almost the same as 1 oz/qt) of TT to water when making samples. I get 5ml syringes in pharmacies. They usually give them away for free when selling liquid meds for kids. HTH

See post #4 :>) the amber is a bit too yellow, the HA is slightly darker and a better match for OB poly.

Update….
I once again want to thank everyone for their help with coloring poly and for using my earlex 5500 in general.
I have sprayed a multitude of projects all with great success, it is very easy and I have had nothing but good results since recieving some starting help a year ago or so. This last request of help tinting was easy and after some tests was a great match and consistantcy.

I started with 1 ml per oz of TT and found it to be too much….I finally settled on 1 ml per 4 oz. I used the Trams tint Honey Amber and small little plastic vials that I picked up at Walgreens that also came with an eye dropper for 2.95 for mixing.
It truly couldnt be easier to match the color of water born Poly to an oil based poly…...

For those of you that are considering using an Earlex, buy the 5500 or better…..don’t be cheap!!! LOL….It is so easy….but I did have some advice from a local cabinet shop…make sure that your material that you are spraying and the items to be sprayed are above 70 degrees and given time to acclimate to that warmer temp…...I have been bringing my shop up to 72, 4 to 5 hours before I spray, and I have brought the poly in the house to warm up the night before. While a few successes do not make me an expert, several folks on here have had issues at lower temps and I wonder if the temperture of the material and products to recieve it are at fault.

Any way, thanks to the folks here for helping me…If I can pass on any help that I have recieved I would surely help..
Mike
