SAKRETE Sand Mix 30 kg – Portland Cement Topping & Bedding Mix for Concrete Repairs, Overlays, Leveling & Paver Applications

Summary

SAKRETE Sand Mix 30 kg combines Portland cement with graded natural sand. Therefore, it offers a convenient solution for concrete repairs, overlays, topping and bedding.

Use this mix for applications from 1.3 cm to 5 cm (1/2 in. to 2 in.) thick. As a result, it suits many residential, commercial, contractor and DIY projects.

In addition, the sand-based formula provides a workable material for leveling and finishing. You can finish the surface with a trowel, broom or brush.

Key Features

• 30 kg (66 lb) bag for renovation and construction projects
• Portland cement and graded natural sand
• Suitable for 1/2 in. to 2 in. applications
• Designed for concrete repairs and overlays
• Suitable for topping and leveling applications
• Suitable for approved bedding applications
• Requires only clean water
• Provides approximately 0.014 m³ (1/2 ft³) per bag
• Supports smooth trowel or textured broom finishes
• Meets or exceeds ASTM C387 strength requirements when used as directed

Furthermore, the pre-blended formula simplifies material preparation. Contractors can reduce on-site measuring, while homeowners can mix the product with clean water and standard concrete tools.

Technical Specifications

SAKRETE Sand Mix contains Portland cement and well-graded natural sand. In addition, each 30 kg bag produces approximately 0.014 m³ (1/2 ft³) of material.

When used according to the manufacturer’s instructions, the product reaches approximately 35 MPa (5,000 psi) compressive strength at 28 days.

For mixing, add approximately 4 L (4.25 qt) of clean water to each 30 kg bag. Then, mix the material until it reaches a workable consistency.

However, avoid adding excessive water. Too much water can reduce strength and increase the risk of cracking.

For best results, keep the mix and substrate between +5°C and +30°C (40°F and 86°F) during application and the required curing period.

Benefits for Contractors & Homeowners

For contractors, SAKRETE Sand Mix provides a convenient pre-blended solution. As a result, you can simplify material handling and mixing on the jobsite.

For homeowners, the product makes many smaller renovation projects easier to manage. You do not need to measure separate quantities of cement and sand.

Moreover, the sand-based formula provides a workable surface for finishing. You can use a trowel for a smooth finish or a broom for added texture.

One 30 kg bag covers approximately 1.1 m² (12 ft²) at 1.3 cm (1/2 in.) thickness. However, actual coverage can vary with application depth and substrate conditions.

Therefore, calculate your required quantity before purchasing. Also, allow additional material for variations, waste and uneven surfaces.

Installation and Usage Guide

1. Prepare the Surface

First, remove loose, damaged or unsound concrete. Next, clean the surface and remove dirt, dust and other contaminants.

Then, saturate the substrate with potable water. However, remove standing water before placing the mix.

2. Mix the Material

First, pour the bag into a mortar box, wheelbarrow or mechanical mixer.

Next, add approximately 4 L of clean water per 30 kg bag. Then, mix until the material reaches a workable consistency.

Importantly, do not make the mix overly wet. Excess water can weaken the finished material.

3. Place the Mix

Next, place the material over the prepared area. Then, work it into the surface and consolidate it thoroughly.

For leveling applications, use a straight board or screed. Move the board back and forth to remove excess material and fill low areas.

4. Finish the Surface

After placement, wait until surface bleed water disappears. Then, choose the finish that suits your project.

For a smooth surface, use a steel or finishing trowel. Alternatively, use a broom or brush when you want additional texture.

5. Protect and Cure

Finally, protect the finished area during curing. Follow the manufacturer’s curing instructions and protect the work from unsuitable weather conditions.

For painting applications, allow the concrete to cure fully. However, always follow the coating manufacturer’s requirements when they specify a different curing period.

Why Choose Us Over Big-Box Stores?

Big-box retailers often provide basic product information. However, choosing the right construction material requires more than comparing a product name and price.

Instead, we provide practical specifications that help you plan your project. For example, you can review the application thickness, water requirement, coverage, yield and strength before you buy.

Furthermore, our product information answers common renovation questions. Therefore, you can quickly determine whether this sand mix suits your repair, topping, overlay or bedding project.

For contractors across Ontario and the GTA, clear technical information makes material planning easier. As a result, you can estimate quantities with greater confidence.

For homeowners, detailed product information reduces guesswork. You can compare the product with your project’s required thickness and application before opening the bag.

Finally, always follow the manufacturer’s instructions. For structural or code-sensitive work, consult a qualified professional.
