I painted some interior wooden doors with emulsion to contest the walls and used a clear satin varnish (that looked like treacle surrounded by the pot) over the top so the emulsion would not get dirty near fingerprints.
The result is dark and bedside light patches. I wonder if it is because the satin varnish wasn't completely mixed when it go on. However, how do I rectify this? I was wondering if the varnish have messed with the emulsion section below hence the seeming uneven distribution of colour. Should I turn over it with a clear add footnotes to varnish or will the patches remain?
Answers: Emulsioning wood is incorrect. And if your varnish be oil-based then it may hold burned into the weaker emulsion and caused the patching. You could enjoy used a water-based acylic varnish over your emulsion (polyvine is the best), but even a matt varnish would have departed it a little shiny - It would own been quicker and cheaper to acquire the colour you wanted within a satin wood paint. And that is what I would do immediately. Rub down and paint over the lot with a proper wood paint - Dulux Satinwood for example.
There is nought to stop you painting over emulsion beside clear varnish,however ,if you emulsioned over an oil base paint that was already on the door it will not grip properly and will start blistering within 6 months,the single way you could grasp patches next to a clear varnish is if there be a contaminant in the brush or the varnish, excluding that you have put the varnish on thicker surrounded by some places giving the illusion of patch. sand off and start again, personlly i would procure the same color within oil basd eggshell.
