Impasto gel, texture paste, modelling paste + oil paint?

I'm a beginner and would like to paint a texturized, rough surface, rich colour painting. I was given Impasto Gel Gloss, Texture Paste (both from Daler - Browney) and Modelling Paste (Amsterdam brand?). My question is, can I use these with oil paint or do I have to use acrylic? I have zero experience using acrylic, so far only oil and only on canvas. Can anybody give me advises on these question and some basic technique or maybe a good website to look? Thank's a lot.Impasto gel, texture paste, modelling paste + oil paint?
A quick look through Daler-Rowney's catalogue shows they do not make an impasto or texture gel for oils - their gels are for acrylics. Also, Royal Talens who make Amsterdam Oils do not make a modeling paste for oils. Please check the labels on the products you have - if it says anywhere on the label ';Acrylic Polymer'; then you must not use it with oils.





Grumbacher makes a product called ';Zec'; which is a fast-drying impasto gel for mixing with oils (sorry can't find a link). Winsor %26amp; Newton also makes two fast-drying gels called ';Liquin Impasto'; and ';Liquin Oleopasto';. http://www.winsornewton.com/products.asp鈥?/a>





I believe you can mix any amount of paint to gel ratio - more gel = more transparent, more paint = more opaque. Mixing with a palette knife first, instead of a brush, gives you the best blending capabilities. Apply with stiff (hog bristle) brush or painting knife. Do a search for impasto or knife painting and you should be able to find some great techniques.

the gel mediums are usually for acrylic paints. you can definitely not mix a gel medium for acrylic with oil paints. they just wont mix properly and it will lead to problems once you start painting. oil paint doesnt really require the mediums because it is so thick. you can just use that thick body of oil paint to create all sorts of texture. you can also mix things in your oil paint like sand or crushed material to give it an interesting texture.
products that are designed for use with acrylics rarely mix with oils because they are water based.


to add texture you can use pencil shavings, shredded paper, sand... just about anything. mix it directly into your paint. you don't need to spend a fortune. just make sure it's dry.
For a texturized painting, especially for a beginner, I recommend you use acrylics. I know, you only know oil, but cheer up!





Oil painting is not nearly as easy as acrylic painting when it comes to clean up, drying time, etc. Also, you have much less problems deciding whether to use various types of additives to achieve certain effects, AND it is less expensive.





Acrylics work the same as oils when actually painting, in that you mix the same colors to get the same effects. The paint itself can be made thin or thick just as in oils, but with much less fuss. You can simply add water to thin it out, or gel medium to thin out the color without thinning out the texture.





If you want your acrylic paints to dry more slowly, just add something called ';Retardant.'; The more you add, the more slowly your paint will dry.





And best of all, acrylics clean up easily with soap and water!





When I allow my students to begin doing pictures in color, I always suggest that if they choose to use paint, they use acrylics as they are the easiest and cheapest. I have them buy one or two smallish canvas boards (around the 9';X12'; size) and practice on those. When your board is used up, you can always paint it white and start again in a few minutes. This way you save time and money practicing your skills.





You may use the brushes you already have for oils, but you can also buy a few more for fine details or large effects. And best of all, every brush I've seen, whether it says so or not, works with acrylics.





And two more things: instead of buying and cleaning palettes, I use a regular dinner plate that I've covered with aluminum foil. It makes a great palette and when you're done you can throw the foil away and your plate is clean.





I also use an ice cube tray to mix up colors I want to save and use another day. When I'm finished for the day I just put a few drops of water on top of each compartment that has paint in it, stick the tray in a zip lock bag and put it somewhere that the dog can't reach.





Offhand, I cannot recommend a particular instructional website, but I'm sure that if you do a web search, you will come up with many links.





However, since you already know a bit about painting, and since I've told you most of what you need to know about what to mix to thin acrylics out or make them dry more slowly, you are actually ready to start. Just do those practice boards first to make yourself feel more confident and you'll do fine.





Since you can achieve any effect with acrylics that you can with oils, plus you actually have a wider and brighter color range, and since they are easier and cheaper to work with, I'll bet that once you try acrylics you'll stick with them.
