Introduction
Granite worktops are renowned for their beauty, durability, and timeless appeal in kitchens and bathrooms. Whether you’re in the process of installing a new granite worktop or maintaining an existing one, sealing is a critical consideration. Over time, granite surfaces may lose their protective sealant, leaving them vulnerable to staining, moisture damage, and wear. But how do you know if your granite worktop needs to be sealed? In this comprehensive guide, we’ll explore the signs that indicate your granite worktop needs sealing, the process of sealing, and the best practices to keep your worktop in excellent condition for years to come.
How Do I Know if My Granite Worktop Needs to Be Sealed?
Granite is a porous stone that requires a protective sealant to maintain its resistance to stains, bacteria, and moisture. Although granite is naturally resistant to damage, sealing helps to preserve its lustre and prevent issues from developing over time. Here are some signs that your granite worktop may need sealing:
1. Water Beads on the Surface
One of the easiest ways to check if your granite worktop is properly sealed is by observing how water behaves on the surface. When the granite is sealed correctly, water droplets will bead up and remain on the surface. This is because the sealant creates a protective layer that repels moisture. If the water seeps into the stone or is absorbed quickly, it is a sign that the sealant has worn off and needs to be reapplied.
2. Discolouration from Spills
Granite surfaces are highly resistant to stains, but they are not completely impervious. Without an effective sealant, spills from liquids such as wine, oil, coffee, or juice can quickly penetrate the stone and cause stains. If your granite worktop has developed dark or discoloured spots after a spill, this could be a sign that the sealant has worn off and your worktop requires resealing.
3. Absorption of Oil or Liquid
Granite worktops can sometimes absorb liquids if they are not properly sealed. A simple test involves placing a few drops of oil or water on the surface of your granite. If the liquid is absorbed into the stone and leaves a dark mark that takes time to fade, it indicates that the sealant is no longer effective, and the worktop needs to be resealed.
4. Surface Streaks or Marks After Cleaning
When cleaning your granite worktop, if you notice that streaks or marks remain after wiping it down, it could be a sign that the sealant has worn off. A well-sealed granite surface should be easy to clean, leaving no streaks or residue behind. If the surface continues to look dull or develop streaks even after cleaning, resealing may be necessary.
5. Feeling of Roughness or Porosity
Granite is typically smooth to the touch, but over time, it can lose its polished finish and feel rough or porous. If you notice that the surface feels more porous or uneven than before, this is an indication that the sealant has worn away, and the stone is exposed to the elements. Resealing the worktop will restore its smooth texture and prevent further damage.
6. Age of the Sealer
Even if you’re not noticing any significant signs of wear, the age of your granite worktop’s sealant can be a determining factor in whether it needs to be resealed. Generally, granite worktops should be resealed every one to three years, depending on the amount of use and the type of sealer applied. If your granite hasn’t been sealed in a few years, it’s worth checking for any signs of deterioration and considering a reapplication of the sealant.
FAQs (Frequently Asked Questions)
Q1: How often should granite worktops be sealed?
Granite worktops should generally be resealed every 1 to 3 years, depending on usage, the type of granite, and the sealer used. Some high-traffic areas may need more frequent sealing.
Q2: Can I reseal my granite worktop myself?
Yes, resealing a granite worktop is a simple DIY task. You will need a high-quality granite sealer, a clean cloth, and some time to apply the sealer and allow it to cure. However, if you’re unsure, it is advisable to consult a professional.
Q3: How long does it take for granite worktops to dry after sealing?
Typically, granite worktops need 24 to 48 hours to fully cure after sealing. During this time, it’s essential to avoid placing any items on the surface to ensure the sealant has time to fully bond.
Q4: What happens if I don’t seal my granite worktop?
If your granite worktop is not sealed, it becomes more vulnerable to staining, bacterial growth, and damage from moisture. Without the protective barrier, the granite may absorb liquids, leading to unsightly stains that can be difficult or impossible to remove.
Q5: What type of sealer is best for granite worktops?
There are several types of sealers available for granite, including penetrating sealers and topical sealers. Penetrating sealers are typically the best choice for granite as they soak into the stone and provide long-lasting protection without altering the appearance of the stone.
Q6: Can granite be resealed if it’s already stained?
Yes, granite can be resealed even if it is stained, but it’s important to treat the stains before sealing. If stains have already penetrated the granite, you may need to use a poultice or stain remover to lift the marks before applying a new sealant.
Conclusion
Sealing your granite worktop is essential for maintaining its beauty and durability. Whether you’re noticing signs of water absorption, staining, or a lack of shine, these indicators can help you determine if your granite needs to be resealed. Regular maintenance and proper care will ensure your worktop remains in top condition for years to come. If you’re uncertain about sealing your granite worktop, it’s always a good idea to consult with a professional to ensure the best results.
