  • Primers ?

    Should a primer be used before painting with acrylic or latex ?

    Personally I seldom use a primer when painting wood with acrylics. It generally depends on what you want to cover. I like to use several wash coats of acrylic as opposed to one heavy coat and let the color "build" with each additional coat. If there are blemishes in the wood that you need to hide then a primer would be in order. If you use a good sanding sealer first and then paint with wash coats you can control how much, if any, wood grain is visible in the finished piece. Additionally, the luster of the finished product is nicer with wash coats than with one heavy coat. When I do use a primer I use Gesso mixed about 50/50 with the acrylic color I intend to use on the project. Wash a few thin coats of that on and let each coat dry before applying the next. Then, build the color you want using several wash coats of acrylic thinned with water. Also let each coat dry before applying the next until you get the depth of color you're looking for.
    If it don't fit, don't force it....get a bigger hammer!!

          Charlie,
          It may depend on the look you are trying to achieve. A primer should sort of seal the wood, allowing the paint or stain or whatever comes next to sit right up there and show - if it is paint, and you want crisp lines or fine detail, then a primer (or, as I sometimes prefer, sanding sealer) will allow you that precision. If, on the other hand, you are just sort of tinting the wood with light dilute coats, then no sealer lets it soak in a bit, and gives you a softer, "woodier" look. And if you're using a wood with ugly or no grain or character, then prime with a dilute coat, follow with more coats of thinned paint, and you've got it.
          In most cases, a thick or heavy coat of paint gives a "plastic-y" look to the project - and that is better left for - well - plastics. (In my humble opinion.)
          I usually have similarly strong opinions on high gloss finishes.

              Dewaxed shellac

              If the wood you want to cover with paint is pine, use one coat white dewaxed white shellac mixed at a rate of 2 pounds cut. (You can buy it pre-mixed in any D.I.Y center). Put 2-3 coats over the knots. Pine is a resinous wood and the resins bleed and blend into the paint (oil base or latex) EVEN IF YOU PUT PRIMER specially over the knots.

              Shellac dries in a few minutes and requires only 45 minutes between coats. Lightly sand between coats with a 200 grits sand paper.

              Don't use foam paintbrush. Clean brushes with denatured alcohol.

                  pre-mixed shellac

                  Following up on Bugatoo's suggestion, I would specifically recommend Zinsser Bulls Eye SealCoat as the pre-mixed dewaxed shellac. Note that they also have a canned shellac that is labeled just as shellac (which I also like, but for other purposes) that is not dewaxed and is a stronger mix. It has a 3 year shelf life and the date is stamped on the bottom of the can.

                      One more thing to mention about shellac

                      You MUST use dewaxed if you intend to use shellac as a primer.
                      If is is not written DEWAXED on the can or bottle, it is NOT dewaxed. Therefore you can't use it as a primer.

                      Amber and Dark shellac are usualy not dewaxed.

                      Also, I forgot to tell that you should slightly sand the shellac between coat or before to apply another finish on top.

                        That's whay I explicitly recommended SealCoat. There may be another pre-mix that is dewaxed, but I don't know of it. I have decanted shellac that wasn't dewaxed and used it under paint (the wax settles) but I wouldn't recommend it as SOP because it is very inneficent (you half to toss out the bottom third or so) and easy to mess up.

                          Great designe! I would have gone a bit further than Linda, Scott and Gladefade I would cut it into more pieces to make shaping easier. Taper the clouds from right to left, taper the wings so that they are lower where they attach to the body. Taper the neck so that it looks like it is going into the...

                          The never ending dilemma. I only get two magazines SSWWC and Wood carving Illustrated. Even if I don't make something in every issue there is usually something in each one that I have never tried and that will either challenge or inspire me. Yes I know that I do test cutting for them and they have occasionally...

                          I would start by tracing your piece on a piece of 1/8" (3mm) material and then cut the back our such that it is a fraction smaller that your project. Then I would cut your piece into two pieces. I mean cut the angel from the cloud. I would then put the cloud on the 1.8" backer and then with...

                          I understand supporting the magazine and agree. I just do not find many projects that fit my desires.

                          I would like to see them do a poll with subscribers to find out what type projects people want to see....

                          First off how thick is the board you cut?
                          When I want something to stand out I use backer-boards 1/8 thick to get the depth.
                          that means you would have to cut the big cutting into pieces to put the spacer behind.
                          for instance the cloud bottom right which his hand is on I would put maybe...
