Your SpecMix Masonry Mortar Distributor

 

We know that consistency matters – especially when it comes to mortar. That’s why Henry Frerk Sons is proud to be a trusted SpecMix Mortar distributor, offering high-performance premixed mortars that meet the demands of professional specifiers and installers.

 

From off-the-shelf mortars to custom color blends, we offer a wide range of SpecMix® Portland-Lime mortars in Type S, N, and O formulations – all preblended to comply with ASTM C270 “Standard Specification for Mortar for Unit Masonry.” Whether you’re a specifier looking for just the right match ora contractor managing a restoration project or fast-paced build, our team is here to help you get the right mix, right when you need it.

 

SpecMix Mortar Types: Type S, N, and O – What’s the Difference?

We carry Type S, N, and O SpecMix mortars, which are preblended with high-quality SpecMix mason sand.. Each mix is formulated for different strengths and applications, so you can choose exactly what your project calls for.

 

Here’s a quick breakdown:

 

• Type S: Strong and durable, ideal for below-grade or exterior load-bearing walls.
• Type N: Most commonly specified, great for general-purpose walls and above-grade applications.
• Type O: Softer and more flexible, recommended for restoration and repointing.

 

Not sure which one you need? Our team is always available to help you make the right call. You can also check out our Portland Cement Lime Mortar guide for a closer look at mortar types.

 

And when color does matter? We’ve got you covered with our in-house color matching services, in-house blending, and canister-based solutions for on-the-spot adjustments. It’s everything you need, without the guesswork.

Frequently Asked Questions

What is custom Specmix mortar matching, and how does it benefit my project?

• We can custom match the mortar to samples you provide, meaning that you get a spot-on match that will blend in with the original. If you can’t find the right color among the Specmix standard colors or our HFS Specmix Type N color range we will create a custom color for your job.

What do I need to provide for a custom mortar match?

• We need a representative sample of the existing mortar to be matched, and it needs to be large enough to accurately show the color and appearance of the existing mortar to be matched. Select a sample that reflects the conditions that need to be matched, while considering that weathering and soiling patterns vary around a single building.

How long does it take to get a custom mortar match?

• Typical lead time is approximately two weeks for laboratory matching (expedited service is available depending on our workload) and upon approval we are generally able to fulfill mortar orders in 1-3 days, depending on our production schedule and the size of the order. Please call us to check lead times, especially in the peak season from April – November. If you don’t have time for a custom match we will also check our library of previous color matches to see if we can identify an acceptable color.

Can Specmix create unique colors that don’t exist in standard selections?

• Henry Frerk Sons will create unique colors using Specmix mortar. Our color matching is virtually limitless.

Are there limits on the types of colors or finishes you can match?

• Colors are only limited by our limits on pigment loading, but this isn’t generally an issue with Specmix mortar. “Finish” in this case will be limited by tooling by the mason but it will also be determined by the aggregate and water content. Finer aggregate creates a “smoother” finish and water content will affect its texture and color. (More water disperses the pigments and tends to affect color, which is why we recommend limiting water content. It also increases mortar volume, and more water can lead to shrinkage and cracking.)

Note: Henry Frerk Sons custom colors are available for Mortar Types N and O.
