Frequently Asked Questions - Building Chemicals
Q1: Is Cement Plasticiser Essential?
A1: While not required, adding a plasticiser can create a smoother, more workable cement mix without excess water, improving the overall quality of the final product.
Q2: Can Washing Up Liquid Be Used as a Cement Plasticiser?
A2: Using washing-up liquid instead of a proper plasticiser can weaken the long-term structural integrity of cement. We recommend using dedicated plasticisers to ensure a solid, durable finish.
Q3: What Happens If Too Much Plasticiser Is Added to Cement?
A3: Excess plasticiser introduces extra air bubbles, making the mix less dense and weakening the hardened concrete. This can also make the cement prone to frost damage, causing it to deteriorate over time.
Q4: What Is Floor Screed Made From?
A4: Screed typically consists of cement, sand, and water, though formulations vary. Traditional screeds use cement-based mixes, while liquid screeds may use anhydrite binders. Additives can further enhance properties like strength and drying time.
Q5: What Are the Different Types of Floor Screed?
A5: Floor screeds come in two main categories: liquid and traditional. These include options like high-strength, quick-drying, and thermally efficient screeds to suit various project needs.
Q6: Can Floor Screed Be Used as a Finished Surface?
A6: In most cases, screed requires a top covering for durability, although some specialized screeds may serve as a final floor finish.
Q7: How Is Screed Thickness Calculated?
A7: Accurate screed thickness is measured using a laser level. We can help assess and set your floor levels to ensure you pay only for what’s needed.
Q8: What Are Patio Jointing Compounds?
A8: Patio jointing compounds fill gaps between pavers, enhancing stability and preventing weed growth, ensuring a durable, neat finish for your patio.
Q9: How Can I Tell If a Surface Needs Waterproofing?
A9: Look for water stains, efflorescence (white powder), or cracks. Surfaces exposed to water or prone to moisture should be waterproofed to prevent damage.
Q10: Is Waterproofing Suitable for Both Interior and Exterior Surfaces?
A10: Yes, waterproofing protects both interior areas like basements and bathrooms and exterior surfaces like roofs and foundations from water damage and weathering.
Q11: Why Are There Different Types of Waterproofing?
A11: Different waterproofing methods cater to specific project needs based on surface type, exposure, climate, and project specifications, ensuring optimal protection.
Q12: What Are Typical Cleaning Product Ingredients?
A12: Cleaning products often contain solvents, chlorine bleach, and preservatives. Labels typically list components along with safety information and usage instructions.
