Construct a Shower That Lasts With Custom Float Bedding Mortar
Installing a shower in your bathroom is a big project, but using the right materials and techniques will ensure it lasts for years to come. One of the most important choices is the mortar used to build the shower pan or base. Custom float bedding mortar is specially formulated to create a strong, waterproof foundation for shower installations.
Selecting the Best Tiles and Materials
The tiles you choose need to be able to stand up to the wet conditions inside a shower. Popular options include:
- Ceramic - budget-friendly, durable, and easy to clean
- Glass mosaic - shimmering appearance, but can be slippery
- Natural stone - elegant look but requires more maintenance
Besides tiles, you may also consider fiberglass or acrylic shower units. The advantage is they have built-in waterproofing. However, tile allows for more customization.
Understanding Mortar Types and Properties
Standard mortar is cement mixed with sand and water. It provides basic bonding strength. Custom float bedding mortar contains polymers and additives to reduce shrinkage and improve adhesion.
Other enhanced mortars include:
- Lime-based - flexibility to prevent cracks but lower strength
- Epoxy-based - extremely strong bonds but difficult to work with
For shower installations, custom float bedding mortar is the best choice for durability. The proper curing and strength gain are critical.
Preparing the Surface
Before applying mortar, the surface must be prepared properly. Follow these steps:
- Clean thoroughly to remove any dirt, oils or soap residues
- Sand smooth any rough areas for better adhesion
- Ensure the subsurface has the proper slope towards the drain
Any existing cracks, pitting or flaws should be addressed first. The goal is to achieve a smooth, uniform surface so the mortar bonds tightly.
Mixing and Applying the Mortar
It's crucial to mix the mortar according to the manufacturer's specifications. Using too much or too little water affects strength and curing. Aim for a consistency that is moist but not dripping wet.
Spread the mortar using a notched trowel in thin, even layers. Scratch each layer to help the next one bond. Build up to the recommended thickness of 1/2 to 1 inch.
Take care to maintain the slope towards the drain as you trowel. A level helps ensure an even surface.
Allowing Adequate Curing Time
Proper curing is vital for custom float bedding mortar to reach maximum strength. It requires slow, controlled hydration. Rushing the drying with heat or fans results in weakness and cracking.
Leave the mortar undisturbed for at least 48-72 hours. Longer is better. Avoid walking on the surface or adding finishes too soon.
Avoiding Common Installation Issues
Two of the most common problems are cracking and uneven surfaces:
- Shrinkage cracks - caused by insufficient curing time
- Bond failure - due to unclean surfaces or improper slope
Inspect for smoothness and use a level tool. Repair any minor flaws before tiles are applied. This prevents major headaches down the road.
Comparing Mortar Types and Costs
Premixed custom float bedding mortar offers convenience compared to site-mixed options. However, quality bagged mortar with polymers costs about $75 per 50-lbs. For a basic 4x4 shower pan, materials cost around $150.
Premium epoxy or urethane-based mortars offer incredible bond strength but run $200+ for a 50-lb bag. Consider strengths needed versus budget.
With proper installation and care, a mortar shower can last for decades. Follow these tips:
- Use gentle, non-abrasive cleaners to avoid eroding grout
- Re-seal grout every 1-2 years to prevent moisture issues
- Inspect for cracks and re-grout or caulk as needed
The shower will stand the test of time with custom float bedding. Pay close attention to preparation, mixing, curing and maintenance for best results.
