Repointing Coverage
Repointing Coverage
Coverage depends on your wall: brick size, stone pattern, joint width and depth all change how much mortar you need. Coverage is based on concentrate. 1 gallon of concentrate mixed with sand makes about 3.5-4 gallons of mortar. Use the Mortar Estimator below the video on this page to estimate what to order.

Pick PHL 5.0 if you're repointing or resetting old brick or stone that takes hard weather: chimneys, parapets or steps.
| Grade | Best for |
|---|---|
| PHL 2.0 | Soft or fragile brick in sheltered spots: porches, protected walls |
| PHL 3.5 | Most lime-laid walls built before about 1920 |
| PHL 5.0 (this one) | Exposed spots: chimneys, parapets, steps and resetting |
Existing mortar hard and cement-based? Use Type N instead.
- Firmest PHL grade - for the most exposed parts of an old house.
- Steps and resetting - repoint or reset brick and stone steps laid in lime mortar.
- No Portland cement - keeps old masonry breathing.
- Mix with your sand - 1 part concentrate to 2.5 to 3 parts clean masonry sand.
- Color pack included - Natural White, Gray, Light Buff, Dark Buff or Dark Red.
How the job goes
- 1. Match. Check the old mortar's color and sand, then mix a small test batch.
- 2. Rake. Remove old mortar to about twice the joint's width, down to a sound base.
- 3. Repoint and cure. Pack and tool the joints, then keep them damp under burlap for about a week.
Sizes
- Quart (sample and small projects)
- Gallon (standard, makes about 3.5 to 4 gallons of mortar)
- 5 Gallon box (makes up to 20 gallons of mortar)
Safety: lime is caustic. Wear gloves and eye protection.
More about PHL 5.0
Chimneys, parapets and front steps take more weather and more wear than any other part of an old house. PHL 5.0 is the firmest grade in our PHL lineup, chosen for those exposed spots, and it is still a lime mortar with no Portland cement, so the masonry keeps breathing.
Mix one part concentrate with two and a half to three parts clean masonry sand, adding water a little at a time until it feels smooth and workable. Stir in the color pack gradually and point a few test joints somewhere out of sight; once they are fully dry, compare them with the old work and adjust. We recommend working when it's above 40°F, and protecting fresh work from freezing while it cures. Lime cures slowly and likes moisture, so keep the joints damp under burlap for about a week and shade them from direct sun and wind. On chimneys and parapets, which catch the most sun and wind, keeping the work covered and damp matters most.
PHL 5.0 is also our grade for resetting loose brick and stone on steps laid in lime mortar, as well as setting replacement brick or stone into pure lime masonry and laying new non-structural mass-masonry walls. Once the mortar has had its initial cure, Mortar Wash gently lifts any haze or smears from the face of the brick or stone, and helps the new joints blend with the old. Test it in a small, out-of-sight spot first.
If the existing step or chimney mortar is already hard and cement-based, Type N is the better match. For sheltered walls, PHL 3.5 or PHL 2.0 is the gentler choice. Finished well, the chimney or steps blend back into the house and keep breathing through the seasons.

Mortar Estimator
Mortar color visualizer
See each shade on a wall
Tap a shade to see it in brick or stone joints. Tapping a shade also picks that color above.
For illustration only. Order a color sample to see the actual color.
Adjust the color to suit your project. Color packs come packaged separately from the mortar, so you can use less for a softer, less saturated shade, or add an extra color pack (sold separately) for a richer one.

Came out beautiful and better than I had hoped
Shipped quickly. Arrived quickly. It mixed easily and adhered to my spalling bricks. So far so good.
The perfect mortar for 126 year old bricks (granite boulder and brick foundation built in 1900). Very happy with the mortar and clear instructions. Thank you ProMason!
Worked perfectly. Stain changed color of existing brick to the tone I was expecting giving it new life and blends with other new finishes.
I haven't had a chance to mix and use the mortar yet. However, the customer service is great. They immediately sent a replacement package of colorant since the original had leaked.
Our project turned out wonderful! What an amazing difference. It completely changed the look of the house!!
Easier to apply than I anticipated.
My first time staining brick and I was nervous on how it might turn out because I was going from dark brown tone bricks to gray tone (before and after photo submitted)Blended my own color combo and It looks amazing.
The stain covers well and a quart did a good amount of surface area. The perfect shade was achieved by mixing 2 colors. It looks great and is a nice brick border update!
The masonry sealer worked great. It was easy to apply and dried perfectly.
So far, so good. It will take time.
I just tried the mortar out. Need to learn a little more about using it as what I applies turned white. Yes it was sunny and hot. I tried keeping it spritzed and ended up shading the work with tarps, but too late. I’ll try again next week since I see a cloudy day in the forecast. Marie
We took down the Wood pan line in our old home. Built in 1880. All the room is red brick. Except for this one spot that it looks like they ran out. Using pro Mason stains, I was able to make coordinate better with the rest of the room. Very happy with the results! It would have been impossible to achieve without being able to dilute and combine the stains to make multiple colors to match the variants in the original bricks.
Working out great so far
This was awesome. It mixed very well, and even though its still curing, it is very hard now. It was also fun to mix up a mortar by hand the same way they used to do back in the day.
I had my steps repointed but they were way to light and slot of cement left on the brick. These stains worked amazing. Darkened the mortar and made the bricks look new!! Love this product! I used dark buff for the mortar and mixed burgundy and dark red for my brick.
