Gypsum Plastering and Useful Tips for Doing It in Kerala
Blog Article
In recent years, gypsum plastering has gained huge popularity in Kerala’s construction industry. It is fast, clean, and gives a smooth finish to walls and ceilings. Compared to traditional cement plastering, gypsum plastering offers many advantages, especially in Kerala’s humid and rainy climate.
In this blog, we’ll explain what gypsum plastering is, its benefits, and some useful tips for doing gypsum plastering in Kerala. If you're building a home or renovating a space, this guide will help you make the right decisions for a strong and beautiful finish.
What Is Gypsum Plastering?
Gypsum plastering is the process of applying a ready-mix white powder made from gypsum (calcium sulfate dihydrate) to interior walls and ceilings. When mixed with water, it forms a smooth paste that can be easily spread on walls. It dries quickly and provides a smooth, paint-ready surface.
Unlike cement plastering, gypsum plaster doesn’t need water curing. That makes the process faster and more efficient, especially in areas like Kerala, where labour and water costs can be high.
Why Gypsum Plastering Is Ideal for Kerala
Kerala has a humid climate with frequent rainfall and high moisture levels. This can affect the performance of traditional cement plaster, which often cracks or absorbs moisture over time.
Here are a few reasons why gypsum plastering is a better choice in Kerala:
No water curing is required; it saves time and water.
Faster setting time: Allows quicker painting and finishing work.
Smooth and crack-free finish: Ideal for modern homes and interiors.
Lightweight material: Reduces load on the structure.
Better resistance to shrinking and warping: Important in coastal and humid areas.
Because of these benefits, many new home builders and contractors in Kerala now prefer gypsum plastering over cement plaster.
Gypsum Plastering Uses in Construction
Gypsum plaster is widely used for:
Interior wall finishing
Ceiling design and false ceilings
Crack repair and patching
Surface preparation before painting
Drywall partition systems (when used with gypsum boards)
Tips for Gypsum Plastering in Kerala
If you’re planning to do gypsum plastering work in Kerala, here are some important tips to follow:
1. Choose Quality Gypsum Plaster
Always select a reputed brand of white gypsum plaster that is known for strength and smoothness. Check the manufacturing date and make sure it is stored in a dry place. Low-quality plaster may lead to weak bonding and cracks.
2. Prepare the Surface Properly
Make sure the wall surface is clean, dry, and free from dust or oil before applying the plaster. For RCC surfaces (like beams and ceilings), use a bonding agent to improve grip, as gypsum alone doesn’t stick well to concrete.
3. Mix in Small Batches
Mix gypsum plaster with clean water in small quantities, as it sets quickly (within 20–30 minutes). Using large batches can lead to waste and a weak application.
4. Maintain Correct Thickness
In Kerala homes, the ideal gypsum plaster thickness for interior brick walls is around 12 mm. For uneven surfaces, it can go up to 15 mm, but too much thickness may cause cracks or peeling. Always use levelling tools to ensure even application.
5. Avoid Moisture-Prone Areas
Do not use gypsum plaster in wet areas like bathrooms or exterior walls exposed to rain, unless you’re using a moisture-resistant gypsum product. These are specially designed to withstand humidity and splashes.
6. Allow Proper Drying Time
After plastering, let the surface dry fully before painting. Although gypsum sets quickly, it takes 2 to 3 days to completely dry, depending on weather conditions.
7. Hire Skilled Workers
Gypsum plastering requires good technique. Always hire trained professionals or gypsum plastering contractors in Kerala who have experience with this material. Skilled workers will deliver a neater finish with fewer chances of error.
Cost of Gypsum Plastering in Kerala
Gypsum plastering may seem slightly more expensive per square foot than cement plaster, but it saves costs in other ways:
No need for sand or water curing
Faster project completion
Less paint and putty are required due to the smooth finish
On average, gypsum plastering in Kerala costs around ₹25 to ₹35 per sq. ft, depending on the brand, location, and labour charges.
Conclusion
Gypsum plastering is a smart, modern, and cost-effective choice for home construction and renovation projects in Kerala. With its fast drying time, smooth finish, and resistance to cracking, it offers great value, especially in a climate like Kerala’s.
To get the best results, always use high-quality materials and follow proper techniques. If you’re not sure how to get started, consider consulting with a gypsum plastering expert in Kerala who can guide you based on your needs.
