Mortar Repair Products

Most mortar repair products come in a tube or generic color of caulking or mortar, but our mortar repair products are custom made for matching your mortar.

Through testing and matching your mortar by analyzing samples, we produce a formula for mortar mix that is custom matched to your mortar. With this matching mortar mix formula, AMR Labs produces custom matched mortar repair products/bags of custom mortar.

To get custom mortar repair products, start by ordering mortar matching services.

Mortar Testing Lab Analysis

AMR Labs is a mortar testing lab providing analysis of hardened mortar samples to determine the composition of existing mortar and create a matching mortar formula, and offers mortar color matching services also. Our lab testing services are often used to analyze and match old historic lime mortar for historic restoration and preservation, to determine mortar types and composition formulas, to determine if a quality mortar was used, or if the mortar used matches the recommended mortar materials for a project.

Mortar Matching Procedure

What are the procedures for ordering Mortar Matching?

Acquire samples of mortar about 1/4 cup or more is best

Payment for mortar analysis (pay online or by check with samples)

Package: Samples in a bag, a copy of receipt for mortar analysis or a check, your name, E-Mail, job name, job address, and shipping address, and a contact phone number.

Send package to us at:

How long does mortar analysis take?

Your mortar testing report and a cleaned sample of the original sand will be shipped to you within 5-10 business days.
Some delays may occur with large orders or volume of orders being processed.

Acquiring A Mortar Sample

Use a hammer and chisel to remove the samples of mortar from the corners of the home or directly from one of the cracks. Then send us the samples with payment or a copy of the receipt for online payments.

Mortar Repair

The most important part in any masonry/mortar repair is the mortar used for repair or replacement of the old existing mortar. AMR Labs specializes in analyzing samples of existing mortar and matching the composition and color. From this formula, we can make custom bags of mortar for your repair project.

Analysis and Matching Existing Mortar

However, analyzing and testing mortar for matching is not limited to historic masonry. It is just as important to match the mortar of today. Mismatched mortar can cause many common masonry problems. Among these are chipping or spalling brick faces, loose bricks, loose mortar, mortar popping loose or popping out, mortar cracking after repairs, mortar separation cracks, crumbling mortar, and many more. These are all resulting from new mortar not matching the existing mortar in the mortar joints. Mortars that are harder than the old mortar tend to pop loose and damage brick faces because they are not bonding to the existing mortar, and mortars that are softer than the old mortar tend to crumble or deteriorate rapidly.

Matching Mortar Composition

Matching the composition of mortar is the first step in matching mortar color for masonry repair.

When restoring or repairing masonry, take the time to match the mortar type and composition. This will include the color and graded particles of the sand which compose the majority of most mortars and can change the color of mortar significantly. We also recommend matching the mortar color pigments or aging as this will effect the appearance of the repairs. Mismatched mortar color makes the masonry repair look bad and there is no reason for the repairs to stand out.

Mortar Testing Services

We offer many types of mortar analysis and masonry testing including mortar color/composition matching. Some are listed below.

Mortar Testing

This mortar analysis analyzes the compressive strength of mortar, the mortar composition, mortar type, the sand gradation, and produces a mortar formula for matching the mortar composition and type of the existing mortar sample being tested or to analyze and compare two samples of mortar to determine if they are the same. This mortar analysis includes compressive strength testing, hydrochloric testing or acid digestion of mortar, magnified examination, weight loss, and sand analysis. A cleaned sample of the original sand is returned to you with the mortar testing report. This test is also used to determine if the old mortar is a historic mortar or rather contains historic lime.

Mortar Matching

In this analysis of existing mortar samples, we test the mortar composition, color and graded particles of the sand, pigments, and compressive strength to determine the mortar formula for matching the old mortar.

This mortar formula is then tested, adjusted, and confirmed to match the existing mortar color for a complete mortar match of the formula, color and composition. This test is commonly used by masonry repair contractors and homeowners looking for diy methods of brick repair to make it easy and accurate, and is used for producing custom bags of mortar.

Masonry Unit Testing

This analysis is designed to test the crushing pressure or compressive strength of mortar, brick, stone, block, or tile, and is used to analyze and determine if the mortar used is a good mortar for the masonry units or to determine what type of mortar should be used with the units. A good mortar is slightly softer than the brick or stone it is used to install to prevent damage to the masonry unit.
