Sairset 3000 - Refractory Mortar /also see Clayburn 50 HD-DC Mortar

The 3100°F HD-DC Clayburn 50 Refractory Mortar is one of our current favourite mortars.  Because it performs better than Sairset for surface coating & repair applications (less shrinkage and cracking when airdrying in surface exposure applications), which is a common use, and because we can sell it at a great value right now, its a good, newer consideration to Sairset.  

Both Sairset 3000 and Clayburn 50 HD-DC come in ready to use 55 lb pail 'wet' refractory (high temperature) preparations, each rated to over 3000°F and can be used interchangeably.  The Clayburn product is not as likely to settle in the pail during transit,  making remixing before use a breeze.

Sairset 3000 is a wet, high-strength, air-setting fireclay refractory mortar rated to 3100°F. 

While we used to keep Sairset in stock more regularly, most people who have compared the two products have transitioned to the Clayburn HD-DC 50 mortar, and, given the pricing is currently better, this is the product we are trying to maintain in stock.

Other Alternatives:

 Thermbond 915, though only rated to 2550°F, and not appropriate for HOT installations, is an economical options for fireplace, chimney and pizza oven repairs.  It is very fine and ships in a dry - just add water formulation.

By far the most abrasion resistant Refractory Mortar we've ever seen on the market is Resitect 45.  Rated to 3200°F in can provide a versatile durable coating in hostile environments.  We've stocked up on this product which is extremely difficult to source.

Sairset 3000 Features: 

• Color = Medium Grey.
• Ideal troweling characteristics for mortar joints in brick linings.
• Add water to the consistency desired (i.e., for dipping)

Common Applications:

• Laying high-duty, super-duty, high-fired super-duty, and alumina firebrick.
• Used as a brick joint mortar, repairing cracks/joints in boilers, industrial furnaces, kilns, flues, and stacks.
• Ideal as a general-purpose refractory mortar.

Application Methods:

• Ready to use/apply as is, or can be mixed with water to thin it out.
• Some will take a shallow container, mix a little water, and dip the bricks in to get a thin, even coating on contact surfaces before stacking.

Note:

• Only apply evenly to the contact surfaces of your refractory bricks, not the wall.
• Only apply a thin layer up to 1/16'' of depth max. It has a thinner consistency, not thick like regular mortar.
• When coating 5 of the six sides of a brick, plan on ~1/2 lb mortar per brick.
• Sairset 3000 can also be used to seal up cracks.

Domes:

When building a brick dome, like a Pizza Oven, many masons prefer a good medium-density refractory such as KS4V+ because it cures much stronger, filling deep wedges and not shrinking.  A castable is structural, whereas mortar is like glue.

Storage:

Since this is an air-set mortar (it does not require heat to set and only a minimal heat dry out to hard cure), if you have any leftovers, it's essential to seal them up. It's recommended that you add a light skim of water on top of the Sairset, put the lid on tight, and then wrap the cover with electrical tape or similar.

If stored at room temperature, it should last a long time. Remember to mix well before using it again.
