I think it is a function of the bonding materials ( adhesive glue). Since this glue looses its binding property under the influence of constant water

you have a point. The white glue is poly vinyl alcohol. The alcohol has affinity for water and isn't as durable as acrylic binder used in quality paint.
All in all, it's not expected for screeding to be left unpainted entirely or over a long time.

@bold Meaning if one has no intention of painting on time, screeding is not advsable?

yes sir. Over a year plus.
The ideal thing is to paint within a couple of months. The screeding won't fail that fast, but the more it dries out, the more paint it consumes.
In fact for best result, the pop emulsion paint can be replaced with a medium quality acrylic paint.
The acrylic binder withstands weathering as is designed for exterior coating.
you can also use the color you would want to use for the finishing so that the screeded wall looks similar to the final color intended to use.
In the picture attached below, the acrylic paint was tinted to match the color they want to use.
The building hasn't been painted, that's screeding with cement.

Rubbiish:

Why do u say so sir?
I think this issue is still open to debate.
It has not really been ascertained which is best, some may say A cement is good for concrete works, B cement for block work & so on....But no outweighing reason so far why one should be the best. I will say dangote is widely accepted & used because of its availability, not necessarily because it is the best.

Dangote is the first 42.5R that set faster than other with much long lasting durability. If you observe, contruction companies prefer dangote to other cements.

spyder880:

Very well explained.
Very clear. A picture of wall screeding in progress. I have an observation, cement brands has something to add to screeding. If you are using Dangote cement to screed, your work will tend to be of a lighter shade of grey when completed, but if you are using Unicem, Bua or Ibeto, the work looks a darker shade of grey.

Oga Spyder. Thank you for the usual and immense contributions. You are highly regarded.

I wish I knew about adding color binder to the cement, I thought that was just for POP screeding...
I have gray cement screed as you have seen too.

white portland cement can be used to give white finish like pop screeding.
cement can also be mixed with the regular colored emulsion to give it the color on screeding.

The 42.5R is the cement grade & setting rate which all cement products has. Are u suggesting a building constructed with BUA or Elephant will wane or collapse before dangote? I don't think so sir.
It is true dangote is mostly used by construction companies & individuals, but my point is it widely used is more of its availability, because his trucks dominates major highways, so no cement dealer will want to stress seeking products limited to certain region.

You are just too sound with what you do!

Would you say that it is better to use an Acrylic-based paint, for the outside walls of a building, than any other type of paint, due to its adherence and weather resistance properties?

Can you or anyone in the house give us an idea about the average price per meter/square, of Screeding?

Thank you for the compliment sir.
I don't have idea of how screeding is charged.
Most architectural paints are acrylic based. The pop emulsion paint and some paints make use of vinyl based binder which isn't as good as the acrylic based.
I think what you meant to ask is the best type of acrylic paint best suited to withstand exterior weathering conditions since there are grades of acrylic emulsion paints also.
The best acrylic paint suited for exterior use is the matte emulsion paint. it withstands moisture better, protects the building against weathering process and aging but still allows the building to breathe through water vapor escape.
many brands name the matte finish weather shield or weather related name to indicate it's ability to protect building against damaging effect of weathering on the building.

Na wa for you oga gbadexy, the way you spill out tiniest details of painting makes you “ oga Spyder” of your own area of work (painting). Same way he details building process.
I wish you can extend your services down East (Abia,Anambra,Rivers). I didn’t know an iota of these but have learned a lot from you. you are indeed a blessing to us. I appreciate.

Oga mi, you are an asset to the academic world. So lucid and seamless explanations. We are really grateful for these in-depth and apt explanations.
Please for layman like us who doesn't know technical terms, which paint is acrylic paint? If possible give brand names please.
Again do you advice applying this same formular you explained to internal walls which are not exposed to vagaries of weather?

Thanks for your kind words sir.
it's mostly outside walls that faces screeding degradation due to the effect of weathering.
You could also do it for the interior if you want a still stronger screeding, since the problem with interior screeding is mostly wear due to constant physical contact.
Most brands would inscribe acrylic on their container but the best way to identify Vinyl based paint is the smell. vinyl binders have sweet smelling odor, so the paint would smell pleasantly.
acrylic binder is mostly odorless, so the only odor emanating from the paint would be additives like the preservatives which doesn't have nice odors.

it's a great honor to be likened to the legend of building on nairaland, @oga spyder.
I have supplied quite a number of projects in the east sir. I have a couple of threads on them and an ongoing one presently at owerri with an interesting story.
The painters said a woman nearby gives them all the ingredients needed to cook when she learnt they were buying food and the children were crying when they wanted to leave.
generally, it's been a pleasant experience that influence my outlook and perspective on life.

What if I choose to be the odd man out and use wall putty on the wall imperfections. Thereafter use a belt sander with 1000-2000 grit to smoothen the surface?

Just thinking.

we charge 6,000 per square meter. It includes both materials and labor. It's a casted concrete and it's very durable

iI guess you are referring to Stamped Concrete, and not Wall Screeding?

If so, how much do you charge "if" the materials are supplied (Sand, Cement, Wires, Granite) while you supply the Chemicals like Sealant, Color, e.t.c and your labour?


#Where are all the other Contractors, Painters and those who do Screeding, una nor wan tell us how much it costs per Meter-square?

Thanks so much for your expose so far on screeding and paints.
If our questions as students, are not considered too much and sometimes baseless, could you please throw much insight into the various materials needed for screeding and their mixing ratios. If possible any other issues that are yet to be discussed or asked on screeding.
This does not suggest that we would do the work ourselves but to put us on the know so as to understand what our screeders are quoting and doing.
Once again, your contributions are most appreciated.

I'm sorry I can't be of help here. I only have the basic idea of the setting process of the plasters having actually produced the pre mixed powdered form of both white cement and gypsum based screeding material packaged in dry form in sack. The spread of the product was low and doesn't last on storage so I phased it out.
It was in the course of the production that I researched and applied the various materials to study their setting characters and properties.
I could only hazard a guess based on the best ratio of aggregate to cement or gypsum to give best plaster if I knew the quantity of filler in the paint.
I do supply pop emulsion strictly on a commercial quantity to distributors and over the course of time, I get screeders to help me test for the drying time of the paint with gypsum powder. my observation of the mixing ratio from the sample quantity is usually mixing the paint to the consistency of regular emulsion and adding the gypsum into it while mixing to give a light paste.
pop emulsion is usually very thick here in lagos hence the need to thin it. but if the pop paint is light, then I assume it would be used like that.
If I were to do a screeding, I would also contact the screeders and go by the materials they quote since that's their area of expertise that they do constantly. you could only at best supervise or have someone reliable ensure all the materials are bought and used or accounted for if you are buying the materials.
The outcome would indicate if they didn't compromise on material.
As for adding binder, the ideal ratio is 3 part water to 1 part binder and used to mix cement and aggregate mix. I think 2 kg or roughly 2 liters of binder per drum of paint is ideal to be mixed with the cement or gypsum powder.
The screeders also do say a bag of gypsum powder can require 2 to 3 drums of paint. mixing with 2 drums paint would be stronger than with 3 drums of pop paint and using sufficient binder would also make significant difference.
I hope you can be able to make sense and pick points from my disjointed explanation.
I was recollecting from memory and typing them as I remember.

Am very grateful for this thread cos it has given a layman like me a lot of information that's very useful.

Capillary water rising.
You most likely didnt do a 'German floor'.
The wall looks plastered, not screeded.
Tiling a wall doesn't prevent upward movement of water.

Water from the bathroom is leaking through the joints on the tile. Unfortunately you have to stop the source of water before any remedy could be done to the plaster.
Even if the plaster is totally scraped off, (which is compulsory) and undercoat applied to seal it, water would still find another weak spot to escape.
I should be promoting my own product, so I won't name any brand. but you could get a gallon very good quality paint in the range of N2500 in the market and get J.k white cement in 1 kg pack and mix it with the paint to form paste and use trowel to apply it to till the joint on the tiles.
The quantity and quality of the binder in such paint would be sufficient with the cement to form a waterproof grout between the joints.
The jk cement in 1kg is preferable to the other kg rates except for the 40 kg pack.
The 2, 5 and 10kg in sacks are mostly repacked here and are full of filler. besides, they are able to absorb moisture in the air and weaken.

topsy23:


Maybe he used 1.5mm for all the lighting, socket, Water heater and AC

Even if, the cheapest and 'fakest' DB is about 27k.. Add labour of 25k. That's already about 50k. The remaining 50k for wires?

Let's assume No AC, no Water Heater just lighting and sockets. It's still impracticable.
