Sairset 3000 and Vesuvius Super 3000 are wet, high-strength, air-setting fireclay refractory mortars rated to 3100°F. Most masons consider these brands interchangeable. Unless specifically requested our fulfillment may vary depending on availability and best pricing.
- Ideal troweling characteristics for mortar joints in brick linings
- Add water to the consistency desired (ie for dipping).
- 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.
- 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.
- 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.
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.
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 around 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.
