Hi guys,
I was just reading a post by another member "dsc" and he mentioned that hed had problems getting things to stick on to his plaster made building.
I work as an interior painter and i have to do alot of plastering.There is a product that we use to treat plastered walls before painting or wallpapering that can be bought from just about every hardware or D.I.Y shop for little money.
The substance usually comes in a litre bottle(or larger) white and milky in apperance and has to be thinned down with water before applying to any plaster.Can be applied with a brush or even a small pump spray.
Anyways if you ask at your local store for a product that leaves walls non porous they will know what i'm talking about.
It's great not only for plaster buildings but can also be used to seal any dio which has been coated with plaster etc. before painting.
Have a good w'end!
Cheers,Shay

Hi
Yes, I must agree with Shay on this topic.

There are a number of sealing agents (some called bonding liquids) which seal loose and flaky plaster finishes. Most work quite well on sealing plaster finishes. Definitely agree, they work quite well.

I found when sealing a wall in my home that the stuff that you dilute smells just like PVA [white] glue, so this is what I have used with water as a dilutant on a number of plaster buildings and it seems to have done the job, with no problems later.

In England the product is known as unibond available in nearly all the DIY stores, White glue or PVA is exactly what it is just thinned down.

Ordinary white glue thinned with water will do the same job.

I use thinned white glue all the time on bases. Over plaster, and over bases that include polystyrene foam, as I use thinners that could melt the soft polystyrene. Just a large soft brush, and brush it in well. It means less paint will soak in and also does away with any scribing dust, that may be left.

Hi all

By the way, for a really neat plaster finish, to scale, I suggest the following:

1. Coat polystyrene foam with tetrion, plaster, polyfill base.
2. While still wet, brush over with PVA / water mix.
3. Sift over dry plaster powder and shake off excess.
4. Let dry for 24 hours.Takes any paint well.

Looks great and gives realistic texture for drybrushing etc.

Cheers
