No. The spar varnish acts as the sealer. Apply a thin coat and allow it to dry. Apply a second coat and allow it to dry. These two coats should have sealed the pores of the wood. Apply the third coat slightly thicker, so you get a nice even "wet look" to the wood.
Seldom any need to seal any tile, certainly not Vitrified, what you will still want to seal is the grout..
Start with a primer, Perma Seal is great. then I would use oil based paint.
Yes, otherwise you will seal in moisture causing potential rot and mildew.
No, you need to remove the tacky coating before anything will stick properly.
I believe that you prime than paint than seal. It depends on the paint you are using and what you are painting A lot of the exterior paints used today don't require any undercoat. However if you are painting over a previously painted surface you must keep preparation in mind.

It is better just to varnish metal models but for all models that you are varnishing it is best to use Matt varnish or purity seal
Yes, plumbers putty typically needs to dry before it can effectively seal pipes.
To achieve a high-quality finish on your wooden project using gloss varnish, follow these steps: Sand the wood surface to a smooth finish. Apply a coat of primer to seal the wood. Apply the gloss varnish in thin, even coats using a brush or sprayer. Allow each coat to dry completely before applying the next coat. Sand lightly between coats for a smooth finish. Apply multiple coats for a deep, glossy finish. Allow the final coat to cure fully before handling the project.
Many artists seal oil paintings with varnish. Other artists use a mixture of varnish and turpentine. Oil paintings can take as long as six months to dry completely.
There are a few ways to seal a oak table depending on how it will be used. Some seal it with only baby oil while others coat it with varnish.
Handling and storing varnish is much less complicated than working with it. As long as you follow a few basic tips, your varnish will keep for extended periods and will be ready for use when you need it.Store at Moderate TemperaturesVarnish should be kept between 50 and 80 degrees F. If varnish gets too cold, it becomes difficult to brush or roll. If it gets too warm in a sealed can, the seal could disappear, and the container of varnish would go to waste.Store Upside DownTo protect the seal, store the can upside down. This practice will prevent air from getting into the container and hardening the varnish. If you need to store leftover paint, use this same trick. It may increase their shelf life up to several years.Avoid Direct SunlightDo not store varnish in direct sunlight. Ultraviolet light can cause chemical reactions in the varnish, and the reactions will affect its ability to cure properly. If you must transfer the varnish to another container, pour it through a paper strainer to prevent contaminants from being passed from one container to the next.
No. You seal the top part of travertine AFTER it's installed.
Seldom any need to seal any tile, certainly not Vitrified, what you will still want to seal is the grout..
If it is cut into the wood, you will need to sand down the entire top to a point below the cuts, being careful not to penetrate any wood veneer (if it is veneered), then stain if necessary, seal, and varnish.
Wood stain MUST penetrate the grain of the wood or it doesn't color. clear coats like Varnish or Urethaneare designed to seal over the stain "color" & keep the wood from being "stained" by all the dirt & spills it endures over time. If you don't sand the old finish off evenly it will keep the new stain from penetrating and it will also allow the stain to penetrate in areas where the old varnish was worn or damaged but not in others making the new stain blotchy & uneven. A good quality urethane is far better and easier to apply than Varnish. .
I would think it should be sealed with something. As a test, lick the slate and see if you get a mineral or dirt taste. If so, this could transfer to the cheese. I wonder if mineral oil applied and buffed off might not seal it well enough. You can mix varnish and lacquer thinner 50/50 and rub it on. This penetrates more and does not leave as much of a surface of varnish.
