If there is only primer on sheetrock, is it ok to go back & add more coats of spackle to correct someones work

Question

The person who lived here before me did a HORRIBLE job spackling.

I can fix this by adding 2 more coats of mud, but the walls are already primered.

Is it ok to spackle on top of primered sheetrock?

I am trying to avoid having to sand away many walls full of primer.

Is it ok to do this?

Answer 1

Yes it is OK.The pros will use a top coat to mud after prime.You will still have to prime the new repairs.

Answer 2

The strict answer is yes.

After installing thousands of sq. ft. of drywall, and applying thousands of gallons of mud I have made it a habit to prime the mud areas at least; after the third application and sanding to show up any voids; etc. Mudding should always be a 3 step process anyway; especially for a DIY.

The more important question for you might be; How heavy is the primer coat and by HORRIBLE do you mean the mudding was never done to FLUSH? OR was actually Over applied and then not sanded FLUSH?

As much as I avoid the use of primer for the sake of time; energy; and often a lack of real need; most will say PRIME everything. To prime raw drywall will lessen the need for heavy coats or many multiple coats of the finish paint.

To further answer Is it OK? It's done all the time over finished paint coats for patching holes etc. and that works fine. No reason not to expect the same over primer.

Answer 3

Sure. That's fine. What I usually do in a situation like this is do a skim coat of mud on the whole wall using my broadest knife. Then a light sanding and see what I've got. You might have to go over it again. Don't forget your dust mask when you sand.

Answer 4

Contact a drywall professional to see if the spackle will stick and not show through the final coat of paint.

Answer 5

So long as it's not shiny and slick- go for it. Primer is meant to be a porous layer suitable for adhesion of the next coats, paint, or otherwise.

Your thinwall spackle'll stick fine.

Answer 6

yes, drywall only has to be sealed one time. If you need to patch , then you may want to spot prime, but not absolutely required. All of these questions are dependent on what type of sheen level you are going to be using, the higher the sheen level, the better the sanding of your patches, and I would definately spot prime if you are using a semi-gloss or greater.

Answer 7

--» 1. No. I can`t tell if someone is my exact opposite or not just by reading the "About Me" section. I don`t judge people. That`s pretty pathetic. 2. I don`t really have a reaction. I just go back to what I was doing. 3. .......... 4. No.

Answer 8

Totally fine...spackle away!

Answer 9

That's what spackling is for.
