   resurfacing a project

   Did you take the finish right back to the timber on the entire surface? The prevoius laquer/paint etc must be totally removed giving the stain 100% chance to absorb into the wood. 

   How are you applying the stain? eg. brush, rag, spraying pre-mixed with laquer?

   Staining can be a bit tricky and pine is particuly thirsty, so you need to work fast and organized.

   If there was a prior finish on the wood, you must use a chemical paint stripper to remove the existing finsih.  Sanding will not do an adequate job getting the prior finish out of the pores of the wood.  Any residual finish will further the natural uneven coloring of pine when stained.  Pine is a very blotch prone wood--perhaps the most blotch prone.  You will need to us a pre-stain conditioner to have any chance at an even coloring.

   blotch problem

   Going to remove the stain that was applied,concidering about using light bleach soulition. Doing light sanding after it dryies. Then go looking for the pre-stain conditioner, that you suggested. I usually use a form brush,then wipe off excess. Howie mentioned that you have to do this in a quick time frame, about how much?

   Blotch

   Pine like maple and cherry are prone to blotching, which is caused by uneven absorption of the stain. Thoroughly removing the prior finish which I assume you will do anyway will not solve the problem. There are a number of ways to deal with this, the most common would be a wash coat such as a very thin coat of dewaxed shellac or glue size.

   Also, gel stains were developed for this reason, the viscosity is such that penetration is limited thus minimizing blotching- at least theoretically

   . There is a ton of info on the web addressing this issue so I won't go into detail. Couple words of advice: Your barrier coat should not be of the same solvent as the top coats, for example, if you use shellac over a shellac barrier coat the barrier coat will dissolve and the stain will leach through and  blotch so in this example a gluesize would be a better choice. It also goes without saying that whatever route you take, make samples before diving into the project at hand
