House latex for filler
« on: January 31, 2016, 09:32:04 AM »

Did I mess up?


True to my signature and based on a tip, I tried house latex for filler on my ABS hull. Tamiya putty seemed too expensive and thick. I tried thinning the putty with hardware store lacquer thinner (white spirit) (I know, there's a Tamiya LT product, but costly), but the putty behaved weird - it went in to an awkward clumpy porridge.


The latex was easy to spread with a sponge-brush and with enough of elbow grease it was fairly easy to sand. It sticks well.
How does it work with Vallejo Model Color? I'm planning to apply a plastic primer before the Vallejo paint.

I am puzzled by what house latex is.
Could you provide a little more info please.

I was not sure about the English.
In Finland we typically use certain water-based paints ("latex") for e.g. walls of rooms indoors.
Hence "house latex".
I have read that the base substance of latex paints has something to do with rubber.
There is no rubbery feeling in the end result, though[size=78%].[/size]

Can you post up a pic of the packaging and maybe I can do a better translation :)


I would suggest a coat of isolator spray before doing any painting just to be certain


Something like U-Pol 720 (Hopefully you can find a cheaper one in Finland as the U-Pol stuff is very expensive over there)

Americans call 'Emulsion' paint 'Latex' paint, so perhaps the Finns call it that as well?  Being waterbased, I would have thought it needs a water based thinner, or maybe even just water to thin it.

I think he might be talking about 'painter's mate' - the acrylic gap-filler stuff in a tube used for decorating.

Sorry folks. I was hospitalised for a little stretch...


It's a proper paint - not a filler. Comes in paint cans that only come with Finnish and Swedish text.


Dispersion paint - thinned with water. Indoors. Not really meant for plastics.
Reaches final cure in 4 weeks (!). This means that it's chemical properties against solvents etc. are reached 4 weeks.


It seems just perfect in terms of handling. I will follow essex2visuvesi's suggestion to use an isolation spray (primer). Would a paint primer not do? See the latter two pics.


By googling "Tikkurila REMONTTIMAALI 20", you can find the data sheet. (Good for you e2v if you read Finnish!)

For the insulator, would a painting primer not do?

About my MOTIP plastic primer.
Is there a chance that Vallejo acrylics don't stick well to it?


I have made a test: by sanding, the paint came off very easy, but I thought I was being too rough and used too small-numbered a grit.

How long had the vellejo been left todry before sanding? I ask because my experience ith vellejo is that it has a flexible vinyl phase before fully curing when it can be a bit fragile.

I let it cure for 2-3 days after the 3rd coat. I hadn't used varnish, yet, when I decided to fix some flaws on the surface. My mistake really was that I didn't let it wait long enough between coats. I think that's it...
