Description
Block walls weep because they’re built to. CMU is an affordable material precisely because it uses less cement — which leaves wide interstitial gaps that drink groundwater and hand it to your basement. Sealers alone can’t fix it: Bone Dry sealers work by reacting with alkali, and pervious block doesn’t carry enough to feed the reaction. The Bone Dry Block Wall system solves it in two steps — the Primer supplies the alkali, and Original or Plus reacts with it to form a permanent moisture seal inside the block itself.
Chemistry that needs a partner
Bone Dry Primer is a colorless, non-toxic, water-based blend of inorganic suspended solids. Sprayed on the interior face, it penetrates deep into the block, filling hairline cracks, small voids, and the interstitial spaces between matrix particles — and depositing the alkali the sealer needs. Then Bone Dry Original or Plus goes on while the primer is still damp, reacts with those deposits, and fills every small space in the substrate to form a permanent water barrier. The wall stays a wall; the barrier lives inside it.
The system
| Step | What it does |
|---|---|
| 1 — Bone Dry Primer | Penetrates deep; fills gaps, cracks, and voids; deposits the alkali the sealer needs |
| 2 — Original or Plus Sealer | Reacts with the primer deposits — permanent moisture seal in the block. Choose Plus for antimicrobial protection in mold-prone basements. |
Why block needs the primer
| Poured concrete | CMU block wall | |
|---|---|---|
| Free alkali | Plenty — sealer reacts fully | Runs short — needs the Primer |
| Porosity | Fine capillaries | Wide interstitial gaps |
| Sealer alone | Works as designed | Not enough — always prime first |
| The system | Sealer | Primer + sealer |
Which surfaces demand the primer?
| Your surface | Use |
|---|---|
| CMU block wall, Shotcrete, Gunite, or extremely porous concrete | Bone Dry Primer + Original or Plus |
| Standard poured concrete slab or wall | Original, Plus, or Pro — no primer needed |
| Painted block (latex, acrylic, polyvinyl) | Strip the paint first — the primer can’t penetrate it |
Application
Good to know: dampen the wall first with a fine water mist — damp, not saturated — then saturate with Primer from a hand-pumped garden sprayer, two full coats at roughly 80–150 square feet per gallon depending on porosity. Use it at full strength only. Time the sealer to the primer: apply Original or Plus when the primer reaches a damp condition. If over-application leaves white deposits, brush or flush them off with water before the next Bone Dry coat — accidental over-application won’t discolor the wall. Keep the surface above 45°F, and shield vegetation and adjacent finishes from overspray outdoors.

FAQ
When should Bone Dry Block Wall be used?
Always use Block Wall on CMU walls and extremely porous concrete surfaces.
Can Bone Dry Block Wall be used on its own?
No. Block Wall comes with a primer to provide maximum strength in pervious concrete applications.
How do I seal high-porosity concrete?
Our concrete moisture mitigation system delivers superior protection from dampness hidden deep within concrete slabs and subfloors. Pervious concrete materials like Shotcrete, Gunite or cement block walls demand our specialized Bone Dry Block Wall.
Specifications
(To ‘Fortify’ Concrete Block, Gunite & Shotcrete With Alkali Prior To Sealing With Bone Dry PCS)
Bone Dry Primer is a colorless, non-toxic, non-flammable, low viscosity, spray applied liquid formulation that adds alkali to porous substrates such as concrete block, shotcrete or gunited concrete prior to subsequent applications of Bone Dry PCS.

Product Description
Bone Dry Primer penetrates deeply into porous substrates where its active ingredients fill small cracks and voids and interstitial spaces between the matrix particles. These deposits will react with Bone Dry PCS to fill all of the small spaces within the substrate to form a permanent water barrier.
Advantages:
- allows porous concrete materials to be internally waterproofed with Bone Dry PCS.
Limitations :
- Bone Dry Primer is formulated solely for cement based building materials and does not effectively penetrate asphalt, metal or wood, brick or masonry
- Bone Dry Primer will not penetrate acrylic or nonporous rubber based paints
- Bone Dry Primer must be applied at full strength to attain the desired results
- over application of the material may cause white deposits to form on the surface. These deposits should be removed by brushing and/or flushing with water prior to subsequent applications of BONE-DRY.
Composition:
Bone Dry Primer is a non-toxic, (water based) blend of inorganic suspended solids which extend throughout porous substrates to provide the additional alkali required to react with the Bone Dry PCS. Bone Dry Primer contains no organic materials or inorganic heavy metals. Bone Dry Primer is neither flammable or explosive and does not emit any harmful fumes.
SIZES:
- 5 Gallon Plastic Pails
- 55 Gallon Steel or Plastic Drums

INSTALLATION
Preparatory Work:
No preparatory work is generally required. However, if the surface is coated with heavy wax, thick grease, recently applied surface sealer, rubber or acrylic paint or other impervious material, remove such materials so that the Bone Dry Primer can reach the surface where it will be allowed to penetrate into the substrate. Accidental over application will not discolor the surface.
Method of Application:
- Dampen surface to be treated (do not saturate) using a fine mist water spray.
- Saturate the surface thoroughly with Bone Dry Primer at an approximate rate of 80 – 150 square feet per gallon, depending upon porosity of the substrate. Low pressure spray equipment, such as a hand pumped garden type sprayer works well for medium sized areas. For large areas, airless spray equipment is very efficient. Small areas can be effectively treated using a spray bottle.Brushes or rollers are not recommended because of the low viscosity of the Bone Dry Primer.Do not allow the Bone Dry Primer to pond or puddle on horizontal surfaces, as a white residue will likely form on the surface. Move the excess material from the low spots on the floor to the high spots with a squeegee, mop or broom. Any remaining material should be picked up with a wet vac or mop.The time for additional applications can be judged by observing the time it takes for the Bone Dry Primer to soak into the substrate. If the Primer soaks in quickly, generally less than fifteen minutes after application, additional material should be applied.
- Bone Dry Primer will not penetrate latex, polyvinyl or acrylic based paints.Unpainted surfaces: Generally, no surface preparation is necessary.
- For surfaces such as basement and outside walls,follow standard procedures as described above.
- Oil, grease or acid conditions: Preliminary cleaning of the surface is necessary before Bone dry primer is applied. Heavy deposits may require scraping, followed by thorough cleaning with a commercial degreaser. After the surface has been cleaned, apply Bone Dry Primer until the substrate has been thoroughly soaked with the material.
- Allow the substrate to dry to a damp condition before applying Bone Dry PCS.
Precautions:
Bone Dry Primer should not be applied to glazed floor or wall tile, or glazed or hard-fired brick where the glaze will prevent the penetration of the material. However, Bone Dry Primer may be applied over these materials if the intent is to seal the grout joints. In such cases, after the PRIMER has sufficiently soaked into the grout, remove all excess material from the surface with a wet vac, squeegee or mop. Wipe the surface with a damp cloth or sponge to remove any remaining film. This will greatly minimize the possibility of a white deposit or film from forming on the tile or brick.
Bone Dry Primer should not be applied to masonry structures having a mortar or grout containing a latex binder.
Bone Dry Primer should not be applied or stored at freezing temperatures. 45 degree minimum surface temperature.
If freezing occurs during storage, agitate the thawed material thoroughly to assure uniform solution.
During outside applications, care should be taken to protect vegetation and adjacent areas from direct spray or overspray.
