And, for the best results on the color match and custom mortars, you may want to get both our mortar analysis and mortar matching services. ]

Q: [Why match mortar composition?]

Q: [Does the sand really matter?]
A: [Sand composes about 60% of the surface of the wall, and can significantly change the color of the mortar and the wall in areas repaired with the wrong color of sand or even different graded particles.]

Q: [Can I fix the mortar cracks myself?]
A: [Yes, you can repair mortar cracks yourself. We have developed some useful masonry repair tools and products to help make repairing masonry easy. Among these are the brick repair guide, mortar matching services, and our custom mortars. We do the hard part for you and make masonry repair easy and affordable.]

Q: [Where do I order custom mortar?]
A: [We provide mortar testing and matching services for creating the formula for making custom mortar, and produce bags of custom mortar. However, we do not produce historic lime. we use type S/SA lime witch have smaller particles. For historic lime, we can produce the formula for you and then Virginia Lime Works uses this formula to produce the mortar containing historic lime. ]

Q: [Can mortar be matched?]
A: [Yes, we match mortar composition and mortar color with precision for repairs that are generally not visible after the new mortar dries. ]

Q: [How do I fix mismatched mortar repairs?]
A: [To fix mismatched mortar repairs, you need to start with an analysis of the original mortar for composition and color matching. Then we can produce new mortar to match the old existing mortar and make bags of custom mortar for your repairs. Then it is a matter of removing the mismatched mortar and repointing the mortar joints with matching mortar. You can have a masonry repair company do this for you, or learn how to repair masonry with our brick repair guide. ]
