A uniformly blended mixture of Portland cement + graded sand (typically a 3:1 ratio). This creates a high‑strength, fine‑texture topping for resurfacing or repairing concrete.
Key property:
No gravel → smoother finish, easier to pack into thin areas.
1. Thin concrete repairs (½–2 inches)
Spalled concrete
Worn steps
Surface scaling
Pitted garage floors
2. Topping & leveling
Leveling uneven slabs
Smoothing rough concrete
Filling shallow depressions
3. Dry‑pack applications
Shower pans
Tile underlayment
Floor slopes toward drains
4. Setting posts or small patches (When gravel isn’t needed)
Slabs thicker than 2 inches
Structural concrete
Driveways, sidewalks, footings (Use 4000 PSI concrete mix instead)
High compressive strength (similar to concrete but without aggregate)
Can be troweled to a smooth finish
Can be used as dry‑pack (low‑moisture, packable consistency)
Portland cement
Graded sand
Approved additives for workability
No gravel → ideal for thin sections.
Consistency options:
Add water until it becomes like thick oatmeal.
Add minimal water until it clumps in your hand but does not drip.
A 60‑lb bag typically covers:
0.5 cu ft at 1" thickness
6 sq ft at 1"
3 sq ft at 2"
(Useful for quick customer estimates.)
Sand/Topping Mix = Cement + Sand (3:1). ½–2 inch কংক্রিট রিপেয়ার, লেভেলিং, শাওয়ার প্যানের জন্য। গ্রাভেল নেই → পাতলা কাজের জন্য সেরা।
| বিষয় | Mortar Mix | Sand Mix |
|---|---|---|
| উপাদান | সিমেন্ট + বালি + লাইম | সিমেন্ট + বালি |
| শক্তি | bonding strength বেশি | compressive strength বেশি |
| ব্যবহার | ইট/ব্লক বসানো | কংক্রিট প্যাচ/টপিং |
| পুরুত্ব | জয়েন্ট ও পাতলা bonding | ½"–2" লেয়ার |
| টেক্সচার | আঠালো, sticky | ঘন, smooth finish |
Sand Mix (also called Topping Mix or Sand & Cement Mix) is a blend of:
Portland cement
Fine sand
Important difference:
Sand Mix has no gravel, so it is smooth and thin-layer friendly.
Concrete Mix has gravel → used for thick, heavy slabs.
Sand Mix is ideal for thin repairs where concrete mix would be too rough.
Perfect for:
Spalled concrete patches
Surface leveling
Broken edges
Smoothing uneven slabs
➡️ Smooth texture gives a clean surface.
For repairing:
Small holes
Chips
Surface scaling
Shallow dips
➡️ Use with bonding adhesive for strong repair.
Sand Mix is used to:
Bed pavers
Level under patio stones
Create a base layer before polymeric sand
➡️ Provides a stable, smooth leveling bed.
This is one of the most common uses.
Used for:
Pre-slope under shower liner
Final mortar bed in tile showers
➡️ Sand Mix is strong, smooth, and easy to slope.
Used to:
Create a mortar bed
Level floors before tile installation
Fill dips and low spots
➡️ Tile installers prefer Sand Mix for solid, flat underlayment.
For:
Filling gaps around pipes
Patching around anchors
Small brick/block repairs
Filling voids
➡️ More workable than concrete mix.
Ideal for:
Small stepping stones
Garden ornaments
Sculpting bases
Molds where a fine finish is required
➡️ Fine sand creates a smoother casting finish.
Sand Mix can be used as a topping coat to refresh old slabs:
Garage floors
Patios
Walkways
➡️ Usually applied 1/2" – 2" thick.
Avoid using Sand Mix for:
Thick slabs (use Concrete Mix instead)
Heavy load-bearing work
Deep footings
Post setting
Structural columns or beams
Because Sand Mix lacks gravel → not strong enough for those tasks.
