Is it OK to use Grout Boost with Polyblend sanded grout. The grout package only mentions water as an addative.

I try to keep products from the same company together. It should work .
It slows the curing time so as to add strength... if you spray it with water it will help also.

Hi,

No you shouldn't. The instructions clearly tells us to use only with "standard cement grout". Polyblend as well as most other grouts available already have an additive in them. A dry latex/polymer that only requires mixing with water. You'll have to search for a brand that does not have the latex in it.

Having said that, We have heard of several complaints with Grout Boost. Mainly with blotchy coloring. You may want to do a search on the product. I'd be afraid of it unless some one will guarantee good results and is willing for you to withhold a large chunk of cash for a period. No reason for anyone to agree to that. So, I would pass.

Thanks jaz... is polyblend a home depot line?. I thought(incorrectly) that you can use a latex add mix with all..
Thanks for the info

THANKS, BOTH. I used it before I had answers, so I'll let you know how it works out, both short and long-term. It mixed well and went on fine, so we'll see. I was using Oyster colered grout, so maybe the potential discoloration won't be much of an issue. Would have used epoxy, but the store was out and the grouting had to get done today so that the counters can go in Wednesday. Fingers crossed. I can't stand dirty gout lines--we won't tell my husband that I may have just made a mess of the kitchen floor! Kitchengrout.

I've used grout boost a few times when I wanted Tec's Accucolor XT series but would have to wait for a special order to arrive or if the color from tec's accucolor pallet was not made in the XT variety. I have had nothing but exceptional results. That being said, Boos tis made by Tec's parent company and the warranty from boost only covers the boost should their be a problem, their only limitation is to refund the cost of the liquid, not the replacement of the grout and the labor to do so and that adding anything but water to an already polymer modified grout kills the manufacturer's warranty (the exception being laticrete's 1776 additive with their sandard protland modified grouts or 4237 additive to make the grout into colord thnset for glass installations). However, when Boost refers to standard grouts, they are not referring to the limited number of unmodifed grouts on the market, they are referring to not adding it to the already "stain free/highly resistant" designer grouts on the market such as Tec's XT series, Custom's Prism, Mapei's Opticolor and Laticrete's Permacolor series of grouts.

I've used it once with polyblend charcoal with nothing short of perfect results, but once again, I am using my experience and judgement in that application and understand the ramifications of my decision upon the warranty provided from Custom and will stand behind my work should the product have an issue later on. Being the original tile was installed on Nobleseal TS with a latictrete thinset, Custom would only stand behind the grout for 1 year anyway. And I knew how I prepared everything, it's drive a tank on it proof.

Thanks, Bljack. It's been 72 hours and the grout lines look great. They haven't been sealed yet, but have stood up to a fridge move (wheel tracks wiped up) and dog paws. Seem solid as a rock. No discoloration noted, so far, all is well!

They haven't been sealed yet


And they won't be. You do not apply a sealer when you have used grout boost. Very important is to keep the installation dry for the first 10 days. If any cleaning is needed, use a dampened rag, no mopping or you will eliminate the effects of the expensive additive you used.

After 10 days of cure time, you can mop as normal.

The above statement is where most people have problems with grout cleanliness. When most people mop a tiled floor, they mop the floor, sometimes they leave it at that, some people wils also go over it with clean water to rinse it but either way, you will have clean tile and dirty grout joints.

Your mop water and even your rinse water will have dirt left in it no latter what you do. The grout joints are usually just below the tile surface , in plain with the pillowed edge of the tile and the dirt left in the slurry of the mop or rinse water dries in to grout lines, over time it builds up or with a traditional grout, soaks in and stains the top layer.

Whenever you clean your floor, throw a towel down and dry the floor right away. Whether you step on it and skate across the floor on it or push it around the floor with your mop or do it on your hands and knees, unless you dry it when done, you are just moving the dirt form the tile surface to an evenly distributed layer over the grout lines.
