Redgrass Hydration Paper 50 Sheets Review – 2026

The Redgrass hydration paper is the official refill for the Everlasting Wet Palette Painter size — and if you own a Redgrass Painter or Painter Lite, it’s the refill designed specifically for your palette. This review covers what makes it different from generic alternatives, how long a pack lasts, which palettes it fits, and whether the price is justified.

Redgrass Hydration Paper 50 Sheets — Complete Review

This redgrass hydration paper is a semi-permeable membrane sheet engineered to work with the Everlasting Wet Palette’s foam system. Unlike parchment paper or generic wet palette paper, the Redgrass sheet is cut to the exact dimensions of the Painter palette and calibrated to allow the right amount of moisture to pass through — enough to keep acrylic paint workable, but not so much that it dilutes pigment or causes pooling. Redgrass Games has been refining this material since their original crowdfunding campaign in 2017, and the current sheets reflect that development.

What You Get

Each pack includes 50 hydration paper sheets cut to Painter size, ready to use with no trimming required. The sheets are the same material used in the Painter Lite and original Painter (orange lid) palettes when purchased new. There is no foam pad included — this is a paper-only refill.

• 50 sheets of premium hydration paper
• Pre-cut to Painter palette dimensions
• Compatible with Painter Lite, original Painter v1, and special edition Painter Lite Blue
• Engineered for 100% foam contact — no bubbles, no curling

Who Is This For?

This pack is the right choice for painters who already own a Redgrass Painter or Painter Lite and need refills. It’s also useful for painters who have tried generic parchment paper and experienced bubbling, curling, or inconsistent moisture transfer, and want to switch to a purpose-made alternative. If you are buying a wet palette for the first time, the Redgrass Games Painter Lite already includes 50 sheets, so you won’t need this pack immediately.

How to Use Redgrass Hydration Paper

Using redgrass hydration paper correctly takes less than a minute and makes a significant difference in results. Start by ensuring the foam pad in your palette is fully saturated with distilled water. The foam should be evenly moist with no standing water on the surface — excess water can over-saturate the paper and dilute your paints before you start.

Place one sheet of redgrass hydration paper on top of the foam and press it down gently at the center, then work toward the edges. The paper should lie completely flat within a few seconds — this is one of its key advantages over generic alternatives, which often take longer to settle or never fully flatten. Once it’s in place, add your paints directly to the surface and begin your session.

Between sessions, close the palette lid to seal in moisture. The Redgrass palette’s TPE gasket creates an airtight seal that, combined with the hydration paper, can keep paint workable for a day or longer depending on humidity and paint type. When you return, check whether the paper is still in good condition — if it is, you can continue using it without replacing it.

Replace the sheet when it becomes heavily stained, develops soft spots, or no longer lies fully flat. With careful use, a single sheet can serve multiple sessions before it needs to be swapped out.

Tips to Extend Sheet Life

Getting more sessions out of each sheet reduces your long-term cost and means fewer interruptions to your painting workflow. These habits make the biggest difference:

• Use distilled water only. Tap water contains minerals that accelerate paper breakdown and increase mold risk. Distilled water keeps both the foam and the paper in better condition longer.
• Don’t overload the foam. Excess water that seeps through the paper and pools on the surface degrades the sheet faster and dilutes your paints. Saturate the foam until it’s evenly moist, then stop.
• Seal the palette between sessions. Leaving the lid open unnecessarily dries the paper unevenly and stresses the material. Close the palette whenever you step away, even briefly.
• Remove dried paint gently. If paint dries on the surface at the end of a session, adding a few drops of water and waiting a minute before wiping softens it without tearing the paper.
• Rotate paint placement. Concentrating paint repeatedly in the same corner stains and weakens that area faster. Spreading paints across the full surface extends usable life.

Common Mistakes With Wet Palette Paper

Most problems painters experience with hydration paper — including paint becoming too thin, paper tearing, or inconsistent moisture — come from a small number of setup errors that are easy to avoid once you know them.

• Placing the sheet on an under-saturated foam. If the foam is not fully wet before the paper goes down, moisture transfer will be uneven and the paper may not adhere flat. Always saturate the foam first.
• Pressing too hard when placing the sheet. Rough handling can create micro-tears in the paper and introduce air pockets. A gentle press from center to edge is enough.
• Leaving paint on the paper for weeks. Even inside a sealed palette, paint will eventually cure or grow mold on the paper if left too long. Replace the sheet after any session where the palette sat closed for more than a few days.
• Using a degraded foam pad. The paper can only perform as well as the foam beneath it. A worn or contaminated foam delivers uneven moisture regardless of how good the paper is.

Pros and Cons

Pros

• Pre-cut to Painter palette dimensions — no trimming needed
• Lies flat immediately with full foam contact and no air bubbles
• Consistent moisture transfer — paint stays workable without becoming watery
• One pack lasts 6–8 months for most regular painters
• Official Redgrass paper calibrated for their foam system

Cons

• Single-use per sheet (not reusable like the foam pad)
• Sized only for the Painter palette — not compatible with Studio XL without trimming
• Foam refill sold separately if needed

How Long Does One Pack Last?

At 50 sheets per pack, the longevity depends on how frequently you paint and how carefully you handle each sheet. Painters who sit down weekly report the pack lasting 6 to 8 months. Those who paint daily, or who replace the sheet after every session, go through the pack faster — roughly 2 to 3 months. The middle ground is using each sheet until it shows clear signs of wear, which typically means 3 to 5 sessions per sheet.

At $10.99 for 50 sheets, the cost per sheet is around $0.22. Even if you replace the sheet every session, the ongoing cost is low enough to make the original paper a practical choice over improvised alternatives.

Compatibility — Which Palettes Fit These Sheets?

The Painter size sheets (ASIN B07B6B7VCH) are cut for the following Redgrass palettes:

Palette	Compatible	Notes
Redgrass Painter Lite	✅ Yes	Perfect fit, same paper included with the palette
Redgrass original Painter v1 (orange lid)	✅ Yes	Designed for this palette
Redgrass Painter Lite Blue (special edition)	✅ Yes	Same Painter dimensions
Redgrass Studio XL	❌ No	Different size — use Studio XL sheets instead
Army Painter Wet Palette	⚠️ Partial	Paper can be trimmed to fit, but not pre-cut for it

If you own an Army Painter Wet Palette, the purpose-built option is the Army Painter Hydro Pack Refills, which includes both paper and foam replacement pads sized specifically for that palette.

Redgrass Hydration Paper vs Army Painter Hydro Sheets

Painters who use both brands sometimes wonder whether the refill paper is interchangeable. In practice, each is optimized for its own palette system, and the differences matter.

Feature	Redgrass Hydration Paper	Army Painter Hydro Sheets
Sheet count	50	50
Price	$10.99	Check current price
Foam included	No (paper only)	Yes (2 foam pads included)
Pre-cut for	Redgrass Painter / Painter Lite	Army Painter Wet Palette
Cross-compatibility	Trimmable to fit other palettes	Trimmable to fit other palettes
Best paired with	Redgrass foam system	Army Painter foam system

The key difference is that the Army Painter Hydro Pack bundles foam pads with the paper, which makes it a more complete refill option for that palette. The Redgrass paper is sold separately from the foam because the Redgrass foam typically lasts much longer and does not need to be replaced as frequently. If your foam is still in good shape, the paper-only pack is the more economical choice.

Redgrass Hydration Paper vs Generic Parchment Paper

A common question among hobbyists is whether ordinary parchment or baking paper works just as well. The short answer: it works, but not as consistently. Generic parchment paper tends to curl at the edges when wet, rarely achieves full contact with the foam, and can create air pockets that interrupt moisture flow. The result is uneven hydration across the palette surface — some areas stay properly moist while others dry faster.

The Redgrass hydration paper is engineered to eliminate these issues. The material selection and cut precision mean it settles flat immediately, maintains even contact, and delivers consistent moisture transfer across the entire surface. For painters who care about repeatability across sessions, the original paper performs better than any generic substitute.

What to Do When the Foam Needs Replacing

The hydration paper is a consumable, but the foam pad beneath it also degrades over time. Signs that the foam needs replacing include discoloration that doesn’t clean out, a persistent unpleasant smell, or uneven water absorption that leaves dry patches on the paper.

Redgrass sells foam pads as a separate accessory for the Painter size palette. Replacing the foam restores the full performance of the system — new paper on a worn foam will still underperform. If you notice the paper no longer lying flat or moisture transfer becoming inconsistent, check the foam before assuming the paper is at fault.

For Army Painter users making the comparison: the Army Painter Hydro Pack includes foam pads with each paper refill order, which simplifies the replacement process at the cost of buying foam more frequently than strictly necessary.

Is the Redgrass Hydration Paper Worth It?

If you own a Redgrass Painter or Painter Lite, this is the practical choice for refills. The paper performs exactly as the palette system was designed, eliminates the frustration of bubbling and curling, and costs less than most hobby supplies at roughly $0.22 per sheet. A single pack will last most painters the better part of a year. For painters who want to get the most out of their Everlasting Wet Palette, the official redgrass hydration paper is worth it.

Frequently Asked Questions

How many sessions does one pack of Redgrass hydration paper last?

Most painters get 6 to 8 months from a single 50-sheet pack with weekly painting. Each sheet can cover multiple sessions before it needs to be replaced.

Can Redgrass hydration paper be used in other wet palettes?

The Painter size sheets are pre-cut for the Redgrass Painter and Painter Lite. They can be trimmed to fit other palettes, but are not sized for them out of the box.

Is Redgrass hydration paper better than parchment paper?

For most painters, yes. The Redgrass paper achieves full foam contact without bubbles or curling, which generic parchment cannot reliably do. The result is more consistent paint hydration across the palette surface.

How often should you change the hydration paper?

Replace the sheet when it becomes heavily stained, breaks down at the edges, or no longer lies flat. With careful handling, each sheet can last several painting sessions.

Does Redgrass hydration paper prevent mold?

The paper itself does not prevent mold. Using distilled water in the foam and cleaning the palette regularly are the main factors that reduce mold risk.
