3 questions, 1:mexican builder's website

volcano - 12-17-2010 at 08:05 AM

1)I had seen a website previously mentioned here of terms and procedures in Spanish to help with dealing with builders, products and tools. Can't find it now....can anyone point me to it?

2)also, advise on a good water based concrete floorsealer, interior?

3) I had been advised to look for an exterior sealer "5 in 1" to seal stucco prior to painting. (and use at 3 to 1 ratio)
Is this product used at different ratios for different purposes?

WOW...I thought you would be buried with answers from all of our experts. Here's something I found that might be fun to use:

I do not know which site you refer to for construction terms, though you can simply start your own guide, by writing down words and their translated counterparts.

The 5x1 is a sealer-it has a milky quality that creates a complete seal, it is generally required for sealing concrete prior to painting. The mix ration creates a more complete or heavy seal, the material dries almost like plastic so, it can cover horrible messes and close it, temporarily. If it's your techo or ceiling, if water is pooling above eventually the sealer will break apart.

Many or most Baja homes are suffering from pealing paint generally caused by poorly sealed concrete overly poorly mixed cement with poor quality materials. Additionally salt can travel through the unsealed concrete.

I have used 5x1 with a 3x1 mixture and it has served me well over a proper mix, some neighbors have endless peeling paint, they mixed it 5x1 and their walls were a mess prior to application.

Another concern is how clean is the water and sand you are using, the dirt in the sand and salt in the sand and water can have greatly reduce the adhesion of the cement. A test can be done with a cup of sand in a glass jar, pour in water and shake and see how the sand settles out. Taste the water? is is salty. Clean sand from up the arroyo the mountaintop is preferred over beach sand. A better option is to not paint at all, instead use cement colors or stains or nothing at all.

There are concrete sealers for sale at most cement stores, they are pricey, about 1000mn for 5 gallons. Though they are used with water, they are not water based, I mean I doubt you can clean the brushes with water or remove the material with water, I don't think. You must use only one brand/type throughout for best application.

Was it Rolly's site?

I've sprayed this waterbased sealer on to protect stucco and it worked well:

Glaze N Seal "Natural Look" . Very easy to use but not available in Baja. Put it in a garden sprayer and don't dilute. http://www.glaze-n-seal.com/sealers.html




For colored concrete interior floors I used this penetrating sealer, which is not waterbased because I mop often. It's been on the floors for 5 yrs and holding up well. The only touch up I have to do is where the desk chair wheels roll over the floor.

I would recommend PPG Plex-Seal 4-6200 interior/exterior clear sealer. It is a water based acrylic, quick drying, durable and easy to apply product. They sell it at FAMSA in La Paz. I believe I paid around 1800 pesos for 5 gal. I don't think that the Comex 5 in 1 sealer is a good choice for exterior use.

an old fella is doing the stucco for me down there now..I believe it is arroyo sand. So colorant won't be included. Great idea on test for beach sand/salt.
Will look for Monoloco's sealer product in San Jose.

What about cement floor sealer?

Just to clarify, the product I recommended is a floor sealer.

so, do you use the same product for stucco sealing, and floor sealing? if so, different mixes? It sound as though that is how the 5 in 1 is used?
(I need interior wall, exterior stucco, and interior cement floor sealers.)

monoloco - 12-18-2010 at 07:06 AM

Use the plex-seal on the floors, the 5in 1 is good for interior walls and is much cheaper, as for exterior stucco, you could use the plex-seal or a product like Thompson's Water Seal.

thank you so much for the thorough advice. I feel I'm in very good hands with it. Have to buy products there this time and avoid shipping fees, budget is very tight.

monoloco - 12-18-2010 at 08:27 AM

Before you use the Plex-Seal on the floor make sure the concrete has cured for at least 30 days and scrub the floor with 30% muriatic acid in water solution.

well, what I was planning on doing, is a couple of very thin skim coats of piso sobre piso with colorant, to simulate the Skimstone product in the usa. I have an existing rough cement slab as a floor now. i had been asking advice here on microtoppings available down there. Found advice that little is available. Researched alternatives. Like the look and ease of the Skimstone (they have a website). then funds got more difficult, and i'm left with simulating the product with alternatives avail there. The instructions for that product is to cure 8 hrs befor sealing. The coats are no more than 1/32 in.
I was assuming I would probably have to use the piso sobre piso at a thicker rate because of it's consistency. does this all sound ludicris for a diy on a permanently small budget?
Really ust want to get some sort of finsh on for now as living in cement dust is nasty. Thanks for your thought and time Monoloco

monoloco - 12-18-2010 at 10:59 AM

I think you wold be pushing it to apply any kind of sealer after only 8 hours. I think that I would coat the existing floor with pegacreto then apply the piso sobre piso in one coat, but I don't have any experience using that product. You may want to try it on a small area before doing the entire floor.

the pegacreto is the cement glue, right? to help layers adhere? What sort of drying time , if any, does it need? Coverage range? thanks
And yes, I will do trials for sure..

monoloco - 12-18-2010 at 04:02 PM

Yeah, pegacreto is the glue, paint it on full strength and then do the piso sobre piso right away, no drying time needed.

monoloco - 12-22-2010 at 08:05 AM

I used Glaze N Seal, the green metal can, to seal my saltillo tile and found that it is nearly half the price in AZ as it is in CA, due to VOC fee's. I wouldn't think that the water based would make any difference, since VOC isn't an issue.

gnukid advice is very good

Old fashion way of doing things...I do it that way in Baja and Sacramento!

A test can be done with a cup of sand in a glass jar, pour in water and shake and see how the sand settles out. Taste the water? is is salty. Clean sand from up the arroyo the mountaintop is preferred over beach sand. A better option is to not paint at all, instead use cement colors or stains or nothing at all.
