Cement Retarder

Can this product be used in Portland and lime mixes?

Yes, it reacts with the Portland.

How long to get shipped

Generally ships next day

do you have this in stock?

Yes

How much extra time will my 226 ounces to 10 yards give me before It starts to setup?

Here are the dosage rates:
Dosage per 100 lbs/100 kg cement:
Air Temperature
40 to 69 °F ( 4 to 20 °C) 2 fl oz (130 mL)
70 to 79 °F (21 to 26 °C) 3 fl oz (196 mL)
80 to 89 °F (27 to 32 °C) 4 fl oz (260 mL)
>90 °F (>32 °C) 5 fl oz (326 mL)

The dosage will vary with temperature, density, and ratio of cement in the batch mix. 3 fl oz/100 lbs (196 mL/100
kg) of cement will extend the initial setting time of portland cement concrete by approximately 2 to 3 hours at 70
°F (21 °C). For longer setting times or in higher temperatures, additional retarder may be needed. For shorter set
times or in cooler weather, use less.

Can I add this along with my powdered color to the cement truck which I have delivering 10 yards. I figure I’ll need 226 ounces of retarder

Yes

can this be used for exposded aggreate concrete

absolutely

Can the cement retarder be used with Type S mortar to increase working time?

Yes it can!

Can this be used on vertical surfaces?

This can be used on any cementious product you wish to slow cure time.

can this be used with 80lbs. bags of Sakcrete concrete mix to slow setting time

Yes, however you need to figure out the actual cement weight in the Sakrete to figure out your dosage.

How much do you add to 1 yard of concrete?

3 oz per 100 lbs of concrete.

can this be used in quikrok..a hydraulic fast set cement grout to slow the set time......what would the amount used be for 90 degree and above temp. ..we only mix about 1 lb at a time ...and use in dry glazing for glass track

Dosage per 100 lbs/100 kg cement:
Air Temperature
40 to 69 °F ( 4 to 20 °C) 2 fl oz (130 mL)
70 to 79 °F (21 to 26 °C) 3 fl oz (196 mL)
80 to 89 °F (27 to 32 °C) 4 fl oz (260 mL)
>90 °F (>32 °C) 5 fl oz (326 mL)

For 90 degrees and above, you would be using .05 oz

will this be ok to use in quikrok a fast set cement grout to slow set time

Yes, this will slow the cure of any cement based product.

How much per yard for 1hr delay

The dosage will vary with temperature, density, and ratio of cement in the batch mix. 3 fl oz/100 lbs (196 mL/100

°F (21 °C). For longer setting times or in higher temperatures, additional retarder may be needed. For shorter set

>90 °F (>32 °C) 5 fl oz (326 mL)

1. Does this work with plaster? 2. Will this maintain cement in a liquid condition for longer time? Or it will maintain cement in a paste condition for longer time?

It will not work with plaster as it reacts with the cement itself.

It will slow the set time of cement and allow for longer working time.

I am planning on buying this if I can also find some HRWR or plasticizers. It seems to be generally unavailable to the public. Do you know where I can find or what I can use as a substitute. I have mediocre knowledge in concrete but I'm a part time sculptor and am interested in attempting "stamp concrete" or "vertical concrete". "Faux brick carving, Etc... I have spent weeks studying and have found it to be a trade secret on the special mixture. Not only that, the ingredients are almost impossible to find.

Issue :I have a large patio that has a lot of slate inbeded in a 5 inch thick slabs of concrete. The top 2 inches of the slabs are a sand mix. The patio is about 40 years old and the concrete is rough porous and and needs some sort of a top coat. I need a product that I can brush on between the slate . The average distance of concrete between slate is 6 inches and the thickness of the new top coat will vary from 1/2 inch to feather edge. This job will be time consuming as I need to brush product around each piece of slate. Each section is 18 x 18 feet with an average of 40 pieces of slate in each section. . I have 6 sections. Questions: What product do you recommend that will allow me the time to complete one section at a time that doesn't have a fast cure time. I have used top and bond on much smaller similar projects before and it worked very well , and I could keep up with the cure time.... My main question is can I add a retarding agent to top and bond to give me the necessary time I need to complete a much larger project and if I can what do you recommend. I spoke to sakrete and the said they had no recommendations on the use of retarding agent. Thanks Pete

Give us a call at 888-391-2227 and ask for Josh. I want to make sure I am understanding your question before I make a suggestion.

If too much retarder is used, will it kill the set? Looking to use this when mixing single 60 pound bags.

I wouldn't say it would kill it, but you don't want to use more than needed based on temperature and how long you are looking to delay. Consult the tech data sheet at the bottom of the product page for recommended dosage.  Keep in mind it is for the pounds of cement,  not the concrete mix

will cement retarder additive reduce the final strength of quick set mortar mix when used as recommended here?

When used as recommended,  the retarder does not have a significant impact on final strength.

what are the ingredients in the cement retarder?

We don't have a list of ingredients however the safety data sheets says all the components are non hazardous.

What is the solution ratio for spray application in exposed aggregate? Square footage rate ? Thanks for your time, Eric

This is not a topical retarder, this is mixed with the concrete.   From the tech data:
The dosage will vary with temperature, density, and ratio of cement in the batch mix. 3 fl oz/100 lbs (196 mL/100

When will you have this product back in?
