Filling gap between molding pieces

Hi, all - this is my first post here (be nice). I have a 1921 "jumbo" Chicago style bungalow in Oak Park, Illinois. The dining and living rooms have the original plaster walls and (what I believe to be) original trim and molding.

My terminology on this is lacking (I lived in a new build condo until 2 years ago), but there is crown molding that starts very high on the wall and extends into the ceiling, giving a similar effect to that of a tray ceiling. I believe that part is original. Below that, on the wall, however, they then added another trip of molding about 4 inches tall. I think this was added later and I have no idea why. It seems to have been there for a very long time, I just don't think it's been there since 1921. Around most of the rooms, a gap has opened between these two moldings. In some spots, it's negligible, in others it's wide enough to slide my fingers in. I can see that behind the gap, the plaster is mostly crumbled and gone.

So that was a lot of words to ask - how do I fill this gap?? I think it's too big for a simple caulk job. And the lack of plaster behind it, makes it seem like it would be difficult to fill.

Thanks!

They make a product just for this called "backer rod" it comes in different widths, all about finger diameter, in 3 or 6 foot lengths or so. You can find it in the caulking aisle or the weather stripping aisle.

Shove is in just past the surface. Fill the remaining area with latex caulk. Let that cure a week or so. Caulk again if needed as latex caulk shrinks as it cures. Prime and paint when the level is as full as you'd like.

gizmo's right. you cant use latex caulk for anything bigger than 1/4".. it will shrink in no time and stick out like a sore thumb

bondo drys rock hard and wont shrink or flex.. only thing is it requires a fair amount of tooling why its active then sanding once cured to look right

Well, I only read the first reply before I was off the Lowes, so I got backer rod and caulk. Although, Lowes had no idea what backer rod was and I had to google it to for them to figure it out, LOL. So far though, it looks pretty darn good, if I do say so myself. Thanks!

Yay.

Bondo doesn't move like your house does. The latex will have some give.

Why aren't we surprised that LOWE'S employees don't even know what's in their store?

lol dj.. you couldnt be more right.. when i have to go into big box stores for materials its scary.. someone comes up to me and asks if i need anything.. "yes, for you to go away " unless its a old guy who's a retired tradesman whos working there now because their body is to broken down to do the work day in day out anymore

it really scares me when i see some of the young employees telling customers how to build something or what to use... 90% of the time it would never pass an inspection

This is why I tell folks to restrict their questions to ones that begin with,

"where can I find the...."

jkirk,

Now you are getting personal. That description of the "retired tradesman" hit too close to home! :)That other "big box" store has been a good fit for me.

You are correct about the public's perception. Unfortunately, it is still too often true, although the present CEO and administration has taken efforts to try to undo the damage done by the former.

Re: Filling gap between molding pieces

no worries. locally my hd has hired several guys who know their stuff, i have no quarrels asking them about tools but as for materials no thanks.. . most of the work i do is high end custom stuff which means not buying through big box stores.

the last thing i asked them was about the paslode 18 gauge nailers that were marked down in price quite substantially.. wondering if they were getting rid of the paslode line because id buy 2 of em right now if i had the cash on me...as the paslode f 18-200 18 gauge is easly the best mass produced pinner on the market.. all the other guns are junk.. basically said if i cant get that gun in 6 months im switching to the grex green buddy which ill have to buy ******.. he never heard of grex.. or occidental leather toolbelts or stilleto hammers .. (sorry im a hardcore tool junky)
