Customer Questions & Answers
-
Question:
What is the main use of Keson PM103BLUE ProChalk Permanent Chalk?
Answer: Keson PM103BLUE ProChalk Permanent Chalk is designed primarily for marking on various surfaces, including concrete, asphalt, and soil. This chalk creates bold and durable lines that resist fading and washing away. Its formulation ensures that it remains visible even in challenging weather conditions, making it ideal for construction sites, landscaping, and other outdoor projects. Additionally, it's perfect for professionals who need precise markings for measuring and layout, ensuring accuracy throughout the project. -
Question:
Is the Keson PM103BLUE chalk safe for indoor use?
Answer: Yes, the Keson PM103BLUE chalk is safe for indoor use. The chalk is made from non-toxic materials, making it suitable for use in enclosed spaces. However, it's advisable to ensure proper ventilation, especially during extensive use, to avoid excessive chalk dust. This makes it ideal for indoor drafting, arts and crafts, or any project that requires clear markings on floors or walls. Its vibrant blue formula also allows users to create striking designs and outlines indoors. -
Question:
How can I best apply the ProChalk for consistent lines?
Answer: To achieve consistent lines with the Keson PM103BLUE ProChalk, it's best to use a chalk line tool or a measuring tape for straight measurements. When applying, hold the chalk at a steady angle and apply consistent pressure while dragging it along the surface. Consider marking from a distance to visualize longer lines and keep the chalk steady for even application. This technique is particularly helpful in construction or landscaping, ensuring that your markings are straight and visible throughout your work. -
Question:
Can the Keson chalk be used on grass or vegetation?
Answer: The Keson PM103BLUE chalk can be used on grass or vegetation, but it’s important to note that permanent chalk may leave behind residual color after it rains or with lawn maintenance. Because of its strong pigmentation, it can be suitable for temporary lawn markings or sports fields. This chalk is ideal for landscapers marking out areas for planting, as it provides clear guidelines without the worry of fading immediately. Just be sure to use it sparingly and test a small area first. -
Question:
What surfaces work best with the PM103BLUE chalk?
Answer: Keson PM103BLUE ProChalk works exceptionally well on a variety of surfaces, including asphalt, concrete, gravel, and compacted soil. Its formulation is specifically designed to adhere and create lasting marks on these materials. This versatility makes it a favorite among contractors and DIY enthusiasts alike, whether outlining a new driveway, marking construction boundaries, or creating garden layouts. If you are planning a project on any of these surfaces, this chalk will ensure your lines endure for the duration of your work. -
Question:
How do I remove the permanent chalk marks once they are no longer needed?
Answer: Removing the marks made by Keson PM103BLUE ProChalk may require different methods depending on the surface. For concrete, pressure washing or using a scrub brush with a concrete cleaner might suffice. On softer surfaces like grass, mowing can help remove the visual impact, although some color may linger. It’s recommended to test a small area first to see how well the chalk comes off. This flexibility is crucial for users who need to make changes or final adjustments in their projects. -
Question:
Is ProChalk Permanent Chalk suitable for outdoor use?
Answer: Absolutely, Keson PM103BLUE ProChalk is particularly formulated for outdoor use. Its durability and resistance to the elements, such as wind and rain, make it perfect for various outdoor applications. This makes it an essential tool for contractors working on building sites, landscaping, or sporting events, where clear and durable markings are essential under diverse weather conditions. Users benefit from its long-lasting visibility without the frequent need for re-application. -
Question:
What is the quantity of chalk in the Keson PM103BLUE package?
Answer: The Keson PM103BLUE ProChalk comes in a 3-pound container, providing a substantial amount of chalk for multiple projects. This quantity is ideal for both small and large tasks, offering long-lasting use without the need for frequent replenishment. Whether you're a professional contractor needing consistent supplies for a big job or a DIY enthusiast tackling various projects, this amount ensures you have enough chalk on hand to complete tasks efficiently. -
Question:
Can I mix colors with the Keson ProChalk?
Answer: While the Keson PM103BLUE ProChalk is made specifically to produce rich, consistent blue lines, mixing it with other colors is not recommended. The chalk's permanent nature means that the unique chemical composition is optimized for stability and permanence in its original form. For diverse marking needs, it might be more beneficial to purchase multiple colors individually to achieve the desired visual effect and clarity in your projects. -
