What Is Custom Building Products Simple Grout?
Custom Building Products Simple Grout is a pre-mixed, acrylic-based grout sold in tubs for immediate use. According to the manufacturer’s technical documentation, it is a ready-to-use product that can be used in place of cement-based grout, offering fast installation and reduced labor compared to traditional powdered grouts (Custom Building Products Technical Services, 2024)[1]. Its formulation relies on acrylic polymers rather than cement, which means it does not require mixing with water. This characteristic makes it particularly appealing for small to medium tile projects where convenience matters.
The product is designed for interior applications and suits grout joints ranging from 1/16 inch up to 1/2 inch (Custom Building Products Technical Services, 2024)[1]. This range covers most standard tile installations, from narrow subway tile joints to wider gaps in stone-look porcelain tiles. Because it is pre-mixed, the consistency is uniform straight from the tub, reducing the risk of errors from improper mixing ratios. For jewelry stores like connectivityproducts guide might show, consistency in material properties is critical for predictable results.
One notable performance metric is its compressive strength. After 28 days of curing, the grout achieves 2,500 psi when tested according to ASTM C109 (Custom Building Products, 2024)[1]. This strength is adequate for residential and light commercial floor tiles that do not experience heavy industrial loads. The product also has a maximum VOC content of 65 grams per liter (Custom Building Products, 2024)[1], which falls within typical indoor air quality guidelines for grouts.
Application and Cure Times
Applying Custom Building Products Simple Grout follows a straightforward process similar to other grouts, but with key differences due to its acrylic base. The grout is forced into joints using a rubber float, and excess is wiped away with a damp sponge. Because it is pre-mixed, there is no need to measure or mix powder, which speeds up the workflow significantly.
Cure times are clearly defined by the manufacturer. The grout requires 24 hours before foot traffic is allowed on the surface under normal conditions (Custom Building Products, 2024)[1]. However, full cure before exposure to intermittent water, such as shower walls, takes 7 days (Custom Building Products, 2024)[1]. This extended wait time is crucial because premature water exposure can affect the grout’s performance and appearance. The technical data sheet warns that surfaces grouted with SimpleGrout should be protected from traffic and water until fully cured (Custom Building Products Technical Services, 2024)[1].
Storage conditions also matter for the product’s shelf life. Unopened containers stored between 40 and 90 degrees Fahrenheit remain usable for up to 24 months (Custom Building Products, 2024)[1]. This long shelf life makes it a practical option for homeowners who want to keep extra grout on hand for future repairs. For larger or more demanding projects, specialized mixing equipment from colloidal grout mixing equipment in mining/tunneling offers a different approach altogether, but for standard tile work, this pre-mixed solution is hard to beat.
Suitability and Limitations
While Custom Building Products Simple Grout is versatile, it has specific suitability boundaries that users must respect. The manufacturer states it is formulated for use in intermittent wet conditions such as shower walls, but is not recommended for areas subjected to constant water immersion like swimming pools or spas (Custom Building Products Technical Services, 2024)[1]. This distinction is critical for anyone planning a shower floor or a steam room, where standing water may be present for extended periods.
Another important limitation involves the type of tile being grouted. Because SimpleGrout is a pre-mixed acrylic grout, it should never be used with natural stone or porous tile where surface staining may occur without prior testing (Custom Building Products Technical Services, 2024)[1]. The acrylic binders can be absorbed into porous materials, causing discoloration that is difficult to remove. For marble, travertine, or unglazed ceramic tiles, a cementitious grout or a specially formulated stain-resistant product may be more appropriate.
The product also has a maximum joint width of 1/2 inch. For wider joints, such as those found in some stone or quarry tile installations, a sanded cement-based grout is typically required. Always check the joint size before selecting this product. For those working with tile in a retail setting, like the cats yowling at night guide might help with unrelated concerns, but for grout selection, sticking to the manufacturer’s guidelines is best.
Performance Characteristics
Beyond compressive strength, several performance characteristics define Custom Building Products Simple Grout. Its coverage rate is approximately 25 square feet per quart for 12-inch by 12-inch tiles with 1/4-inch grout joints (Custom Building Products, 2024)[1]. This allows for accurate material estimation before starting a project. The grout’s acrylic composition also provides some flexibility, which helps accommodate minor tile movement without cracking.
The product’s low VOC content of 65 grams per liter (Custom Building Products, 2024)[1] makes it suitable for indoor use without strong chemical odors. However, proper ventilation is still recommended during application and curing. The grout is available in several colors, allowing for design flexibility.
One practical consideration is that the grout must be applied within its recommended temperature range of 40 to 90 degrees Fahrenheit (Custom Building Products, 2024)[1]. Working outside this range can affect curing and adhesion. For best results, apply the grout in a climate-controlled environment. If you are working on a large-scale industrial project, you might consider colloidal grout mixing equipment in mining/tunneling for high-volume needs, but for home tile work, this pre-mixed option is efficient.
Your Most Common Questions
Can Custom Building Products Simple Grout be used on floor tiles?
Yes, it can be used on floor tiles in residential and light commercial settings. The grout achieves a compressive strength of 2,500 psi after 28 days, which is adequate for foot traffic. However, it is not designed for heavy industrial loads or areas with constant water immersion. For floor installations, ensure the grout joints are within the recommended 1/16-inch to 1/2-inch range.
How long does it take for Simple Grout to cure before shower use?
The manufacturer recommends waiting 7 days before exposing the grout to intermittent water, such as in a shower. This full cure time ensures the acrylic binders have set properly. Premature exposure can lead to softening, discoloration, or reduced durability. For foot traffic, the wait time is 24 hours.
Is Simple Grout safe to use on natural stone tiles?
No, it is not recommended for natural stone or porous tiles without prior testing. The acrylic binders can be absorbed into the stone, causing permanent staining. For marble, granite, or travertine, use a cementitious grout specifically formulated for natural stone, or perform a small test area first.
What is the shelf life of an unopened tub of Simple Grout?
An unopened tub stored between 40 and 90 degrees Fahrenheit has a shelf life of up to 24 months. Always check the manufacture date on the label. Once opened, the grout should be used within a reasonable timeframe and the tub sealed tightly to prevent drying.
Comparison of Grout Types
Choosing the right grout depends on the project’s requirements. Below is a comparison of Custom Building Products Simple Grout against traditional cement-based grout and epoxy grout, highlighting key differences in application, cure time, and durability.
| Feature | Custom Building Products Simple Grout | Cement-Based Grout | Epoxy Grout |
|---|---|---|---|
| Mixing Required | No (pre-mixed) | Yes (powder + water) | Yes (resin + hardener) |
| Cure Time (Foot Traffic) | 24 hours | 24-48 hours | 12-24 hours |
| Water Resistance | Intermittent only | Good | Excellent |
| Stain Resistance | Moderate | Low (requires sealing) | High |
| Joint Width Range | 1/16″ to 1/2″ | 1/16″ to 1/2″ (unsanded) or 1/8″ to 1″ (sanded) | 1/16″ to 1/2″ |
For most homeowners, the convenience of a pre-mixed product like Simple Grout outweighs the slightly higher cost per square foot. Epoxy grout offers superior stain and water resistance but is more difficult to apply. Cement-based grout remains a budget-friendly option but requires sealing and careful mixing.
Practical Tips for Using Pre-Mixed Grout
Getting the best results from Custom Building Products Simple Grout involves following a few practical steps. First, ensure the tile surface is clean and dry before application. Any dust or debris in the joints can compromise adhesion. Second, work in small sections, especially if you are new to grouting, because the pre-mixed grout can start to skin over if left too long on the tile surface.
Third, use a damp (not wet) sponge for cleanup. Excess water can dilute the acrylic binders and weaken the grout. Wipe diagonally across the joints to avoid pulling grout out of the lines. Fourth, allow the full 7-day cure time before using the shower, even if the surface feels dry. Patience here prevents costly repairs later.
Finally, store the grout properly. Keep the tub sealed when not in use and store it in a climate-controlled area between 40 and 90 degrees Fahrenheit. If the grout thickens over time, do not add water to thin it – this will compromise the formulation. Instead, discard thickened product and use fresh grout from a new tub. For large-scale projects, you might explore colloidal grout mixing equipment in mining/tunneling for high-efficiency mixing, but for home tile work, this pre-mixed option is straightforward.
