Drywall repair and painting/texturing questions...?

Question

Here's the deal...a couple years ago I had my garage insulated with the blown-in type stuff...as a result there were holes in the wall about every 4 feet. I used some mesh tape to cover them and then used joint compound on top of the tape. I plan on using a spray texture to retexture the entire garage to hide the holes. Questions:
1) Do I need to use a primer before spraying on the texture (like over the repaired areas)?
2) After spraying on the texture do I need to use a primer or can I just use a latex paint and go for it?
3) I also plan on spraying the ceiling as some of the "popcorn" is coming loose....can I spray over the old stuff?
Keep in mind this IS a garage but I would like it to look decent as I run a small business out of my garage and have people over to look at products every few weeks. Thanks a TON in advance!

Answer 1

No offense, but BIG sigh!!!

I get it,,, that texturing HIDES a lot of faults,,, but reconsider texturing anything that isn't currently.

After installing Thousands of sq. ft. of drywall, and applying Thousands of gallons of paint, I think I know of what I speak.

I'll give you my thoughts, with respect, and you decide the effort you wish to engage in.

Are the holes all at a same level? IE: 7 ft off the floor?

Easy way out,,, Decide where your studs are, and use 1 x whatever, pine, screwed into the wall appropriately,,, As molding kinda, then paint to match the wall. That way it won't strictly matter how sloppy a patch job is.

OR,,,, Forget mesh tape. Depending on the size of the holes, patch them with drywall patches and mud, sand, paint.

You do not need primer,,, unless you plan to go from a Dark wall to a lighter color.

Latex satin or semi gloss in a garage is acceptable.

Again, and with no offense,,, The popcorn may not be your fault, but gads it's so 1970's,, even in a garage. Do not waste cash and effort redoing the entire ceiling if you don't have to... Aerosol cans for patching can be found in a decent Home DIY store. BTW,,, Do the ceiling before you do anything else. Remove the vehicles tarp the area and do the patches.

Answer 2

question 1 yes use primer it lets the dry wall soak it in and not your paint less expensive that way, more than likely in my past experience u cant get two paints that are paint on different times to mach up best is to paint the whole room again might seem like alto of work but if u don't u will notice the difference in the long run.
For question 2 i am not for sure on what ur meaning sorry
For question 3 it is best to scrape off the old popcorn it will come off with easy, re prime the ceiling with primer, and be very careful when spraying the Spackle on it is very easy to get it think in one area and thin in another it is hard to get an even amount cover and if u don't get an even amount cover it will have a shadow effect to it. Hope this is helpful.

Answer 3

Q1) no the mud or Spackle will last longer if you sand and dust the touch ups.
Q2) You should prime it all so that you do not waste paint and time.
Q3) If you spray over the old it will fall, to look right just spend a day gently scraping the old down and lightly sand the rough spots
and paint the hole thing at the same time.
PS I would scrape and clean and sand be for anything ells.

Answer 4

It would be a good idea to prime your patches with a flat latex,ceiling white is fine.After spraying texture you can use latex paint and go for it.And on the ceiling take a broom and sweep the cobwebs off then where its comming off knock off the loose stuff ,then spray those areas first, let them dry a while ,then do the whole thing

Answer 5

Just an idea. As I cant see your remodel space. You may want to consider Screwing 1"x4" BOARDS perpendicular to the 24"O.C. direction. Put these boards 16" ON CENTER. Use Screws on the boards...Fine Thread 2 to 2/1/4inch plus phillips head screws. You may also want to soak the screws in a light oil before installing in the old dry ceil truss. Or maybe even predrill. but it is just doing this right to give your sheet rock a good solid support. Then install 1/2 sheet rock using sheet rock screws with a screw gun...you can either rent one or buy one online used??? Tearing out the old sheet rock is a mess, Plus the insulation above it? Best to just seal it off and start with a good installation. Good Luck.

Answer 6

dont take this the wrong way pal but every can explains what to do prior to performing the work.
answer #1- prime it IF the instructions on the texture say to do it
answer #2- Primer it IF the paint you plan on using says to or the texture instructions say to prime it
answer #3- Spray over it only IF the instructions on the material say you can otherwise prime it...
your asking us questions only YOU can answer with the materials you use on hand
