    How are samples tested?

    • Determine mortar type

      • Relative crushing pressure test

      • Acid reactivity

      • Weight loss after acid dissolving binders

    • Determine formula

      • Based on mortar type

      • Acid reactivity

      • Weight loss

      • Examine remains after acid testing

    • Formulas and Testing are based on ASTM testing standards.

    • Determine Mortar Color


  • send you a sample of your sand rinsed during analysis to compare to when picking your local sand.

  • check for known contaminates in your mortar

Crushing Pressure and Sand Gradation can only be approximated due to the size, age, and shapes of samples being tested.


AMR certifies that the formula produced for matching your mortar will match your existing mortar in general crushing pressure and color making the repairs more durable, more accurate, and virtually invisible upon completion. (Mold and mildew may need to re-grow naturally.)


Don't guess at your mortar match. Get it certified and lab tested.

What if I need more bags?

  • Your order is kept on file with the formula. Simply place your order for more mix, and refer us to the previous order placed. We will need your name (company), and job name/ address to pull up the file.

Each formula is guaranteed to match (within a reasonable tone) in the color and texture to the samples provided from your home. Mold and Mildew may need to re-grow in the pores to complete the match. This part of natural aging we cannot recreate because these tones vary around your home and change throughout the year.

Most mortar matches are not visible immediately upon drying.


AMR Labs is dedicated to providing quality brick and mortar repair products and services. Among these Services, we offer mortar analysis and mortar testing. These are part of our mortar matching services.

Matching the mortars type and crushing pressure are vital for several reasons. The most important reason is that improper mortar will not bond to the original mortar in the joints correctly. If the mortar is too hard, it will deflect and often causes damage to the bricks. If the mortar is too soft, it tends to crumble or deteriorate and is often unable to carry the weight of the brick. Both of these, allow recracking and can cause additional damage or danger of falling brick or walls.

Mortar matching is achieved through a number of tests of samples from your mortar. The first test in our mortar analysis is a crushing pressure test to determine the mortar type. Different mortar types will crush at higher pressures. At this point, your crushed mortar sample is washed through a hydrochloric test from which we derive various details about your mortar including the color and gradation of the sand used. Only after we have obtained all of these details about your mortar, can we even begin to match the color of your mortar.

There are many masonry products available on the market for new construction, and many companies who try to use them for repair. This simply cannot work. These products come in grey and white and require full package consumption at time of use to achieve the labeled mortar type. When small portions of these bags are used to blend a matching mortar color, there is no way to know how much of the portland or lime that make the mix are being used. This makes the resulting mortar type unknown. This is why we mix from the base units to create a matching mortar. It is the only way to know what type of mortar and crushing pressure is being created.

With this starting point, we match the grey tone of your mortar to our color charts, and begin adjusting pigments as needed.

After, your mortar color is matched, AMR Labs can produce custom bags of pre-matched brick repair mortar for your brick repair project.

We have put together many brick repair training tools to help you complete the brick repairs around your home. Among these are "The Brick Repair Guide" and various brick and mortar repair training videos.
