What's the difference of White Cement vs Plaster Filler Putty? Are they same?

Best ask shop that got sell them

Depends on the putty materials. Usually filler putty is just for filling any small holes or cracks, it's not meant to repair, it's just for anesthetics purposes. No strength

White cement is well white colored cement. If mixed with water with proper water cement ratio, it will be as strong as normal cement cube. You can even mix with clean sand to make mortar and gravel to make concrete just like a regular grey cement.

different function.
putty filler as the name implies are used more as a filler to fill the gaps.
where white cement usually people used when they want to make the wall texture to be smooth, it need a lot of work cause you need to do alot of skimming after applying it

So. It's just a regular cement as what grey does?

Oh, so white cement could be used for coating or skimming? But can it apply on Plaster Board like Plaster Ceiling?
Besides, the Filler Putty can't function as coating and skimming surface (Plaster Ceiling or Board)?

plasterboard for partition/office wall?i always use flaxi brand stopping compound..can be use on gypsum partition n plaster ceiling..go to plaster ceiling shop they sell 1kg/pack..the tricky part is to mix the compound n water..

Appreciate your kind reply!
I'm new, and normally grabbed those PYE Filler powder to fill-up some holes and cracks on Plaster Ceiling (Toilet). I know nothing about Coating or Skimming products! So just thinking of whether the PYE Filler Powder could be used as Coating or Skimming product? Or, it's different material?

i think PYE is for skimming on cemented wall and those flaxi for partition/plaster ceiling board..i think diff material as those pye if already harden u can soften it back using water if not mistaken..flaxi cannot.

Oh...so, Flaxi is White Cement, which is Cement, once got Hard, it fixed, unless drill or hammer to break it?

After reading your explanation, it seems I have received the wrong advice. I have spralling concrete on my bathroom ceiling and I was told to use putty. Another shop recommended using Davco k11 rapid plug. I have a 1kg white cement at hand. What should I use? I have already applied anti rust coating on the exposed bars.

spalling concrete, need to make mortar mix rather than just white cement. use 3 parts sand to 1 part cement. then patch over the exposed bars. its not easy work, you better get a handyman to do this if you no experience. you need to apply quite a lot of pressure when troweling/pressing in the cement or it will be weak.

that shop is recommending you a premixed rapid setting mortar mix (means already have sand mixed in with cement), good for sealing leaking walls and wet places.



most importantly, have you checked why your ceiling is spalling concrete? normally it means you have water leaking from above.

Is davco k11 a non shrink grout cement? Your case, use only non shrink grout cement to trowel over.

You can buy it in prepacked.

Watching this video makes me understand why the previous repair in 2011 by the contractor failed so miserably. I didn't do my homework then and trusted him. What is the yellow tube thing that was used to seal cracks?
I was told to use sealer paint and Jotun Majestic Sense to cover hairline cracks on the wall.And if the hairline crack is too wide, use putty first. Now I know I have to stand 3 feet away before I call it a hairline crack!

The actual label on the Davco tin doesn't have this description "non shrink grout cement".
....will try to upload a low resolution image tomorrow....I have just found ANOTHER two problem areas:
1) one tiny section of spralling concrete in one bedroom
2) a section of the wall in the sitting room is partially plastered because it was hidden by two cabinets.

That davco will work as it is a type of cement mortar mix that is used to seal leaking holes very quickly ( the cement hardens within five minutes). However it is expensive and you need a lot of it To patch your spalling cement since your rebar is visible.

Just call a contractor. Tell him/show him the video and tell him you want that kind of repair. But also ask him to check the roof above to make sure there is no water leaking.

This tiny one in the bedroom, I can patch it myself? Putty, white cement or Davco?

scrap out all the surrounding paint, and any loose plaster, beginner can use putty if the patch of plaster that came out is not too thick (< 5mm). apply in thin layers as the first layer will likely have cracks after it dries. sponge it with a car wash hard sponge that is just damp to smoothen it and conceal any fine cracks after.

but to me, the problem looks like you might have a leak from above as the loose plaster is only at the edge of the ceiling/wall. touch the ceiling see if its damp after rain.

Sorry, I am a novice here. You mean scrap off the loose portion and touch the ceiling to see if it is damp after rain (it's raining everyday now) before doing any mending?

This one can DIY with white cement or putty right? Sitting room wall partially plastered. The unplastered wall held remnants of the old wallpaper. I have washed out the glue with hot water and left it to dry for 2days.

High spot or remnants.. use a block of wood and 80 grit rough sandpaper remove excess material dulu.
Wipe down w damp rag remove loose dust.
The roughage is good for putty to adhere to.

Putty has expiry date so chk when buying.
If u open up the putty tub let it breathe 5 min like wine then it stick better and more pliable when compressed with metal scraper.

White cement need to cure longer. Otherwise when u paint over uncured part the gassing off makes pimples on the paint.

looks to be the same thickness as the pink part, just unpainted. paint it pink instead of plastering.

Unless the whole house is under renovation and the workman is always there, all repair work on minor ceiling spralling are completed in one visit. There is no luxury of time for the coating on the rebar to dry or the concrete to set. The contractor will just paint over and move to the next job. This is what I have heard from friends who hire contractor to fix their bathroom ceiling.

You are right. That Davco is 7X the price of white cement and putty. My first attempt to prepare the mix was too slow and the whole mixture turned into a rock before i could apply on the ceiling. Yes, it sets in five minutes. There was no time for proper skimming. I am using Davco now for the bathroom ceiling that has an exposed rebar.

The other cracked ceiling in the bedroom was thankfully just the plastered celing coming off. It wasn't damp. I patched it with putty.....will spread another layer of putty tomorrow before painting over with Vinelex and antimould paint the next day.

Good to hear that, normally i use davco type products to seal gaps in drains and joints where water is flowing, thus the need for a very quick setting mortar. The other use for that type of cement is to “hold” rebar or some other pieces of item i need to place on concrete before applying the main concrete. It sets so fast that you can use it like an extra pair of hands.

Many thanks to diffyhelman2, ceo684 and jojolicia for your advice and reassurance. I got the job done. It was the most difficult part of the painting job.
My apology for a late greeting......Happy New Year, everyone!

depends on what u use for. small internal wall cracks or holes use putty. bigger cracks use cement
