## Overview

Liquid Rubber MetalSafe Sealant is a versatile, high-performance waterproof coating designed for metal roofs and various surfaces. It offers superior corrosion resistance, UV stability, and easy application via brush, roller, or spray. With excellent coverage and fast drying, it forms a durable membrane that protects against leaks and weather damage both indoors and outdoors.

## Description

Liquid Rubber Metalsafe Sealant is a sealant that is easily brushed on and cures into a waterproof membrane. It can be used in many applications where you need to create a watertight seal. Metal roofs, ponds, lightly rusted areas, and more. Use Liquid Rubber Seam Tape or Liquid Rubber Geo-Textile to bridge seams, joints, vents, protrusions to create a long lasting repair or rejuvenation. Apply when temperature is above 5C/41F. Apply to a dry surface, free of dirt, loose flaky paint and coatings, oil, grease, silicone, coal tar or other contaminants. Typically cures within 24-48 hrs. Do not freeze. Store in a warm area. Do not apply in wet conditions or if rain is forcasted within 24 hrs. Not meant as a constant walking surface. Coverage - Vertical Surfaces - Apply a minimum final thickness of 1 gallon/30 sq ft (2.8 sq m). It should require around 2-3 heavy coats to achieve a 30 mil. (0.76mm) (DFT) membrane. Flat/Ponding Surfaces - Apply a minimum final thickness of 1 gallon/15 sq ft (1.4 sq m). It should require around 4-5 heavy coats to achieve a 60-80 mil. (1.5-2mm) (DFT) membrane. Apply next coat when dry to touch and nothing is wet underneath; tacky is okay. Generally 12-24 hrs between heavy coats. Amounts vary depending on surface roughness. Use all material up to achieve a long lasting membrane. Avoid hot, direct, intense sunlight during application. Remove Painters Tape while still wet. Membrane will turn brown in ponding situations due to surfactants. Will dissipate over time as the water cycles and cleans. Clean Up - Use soap and water or mineral oil to clean skin.

Review: I was thoroughly impressed with this product. I have a WWII era Quonset hut that is partially covered by a roof and partly exposed. The exposed part was getting rough but not rusted through anywhere. I cleaned with a very stiff bristled brush and rinsed with hose and let dry. This stuff covered amazingly. I couldn’t believe how much coverage I got out of this. I ordered 10 gallons and was afraid that might not be enough. I ended up only using about 4 gallons. I even tried to apply it as thick as I could. It fills in and covers pin holes and old screw holes very well. For reference I painted the end 10’ of Quonset hut with 4 gallons. This also works good for dipping tool handles into such as pliers, channel locks, or hammers to put a new rubber coating on them. I wasn’t sure about this product when ordering but I am completely satisfied and can definitely recommend. Worked great for me. It did stop all of my leaks btw.
Review: used this to seal up my metal roof that had some leaks, very easy to apply. The material is strong and coverage is great, this was a cost effective solution to provide extra durability to my structure.

## Questions & Answers

**Q: I have a metal trough that i want to turn into a fish pond. would i use only this or should i use this product, then follow with reg liquid rubber?**
A: Hello.
Thank you for reaching out to us.
I recommend that you use Liquid Rubber NeoPond Sealant as this coating was designed for ponds, has been tested to be fish and plant safe, and is much easier in it's curing process (in regard to ponds).
You will also, likely need Liquid Rubber Multi-Purpose Primer and Liquid Rubber Geo-Textile for your project.

Liquid Rubber USA/CAN has great technical support, application info and video's.
Have a great day!

**Q: can it be applyed over another roof sealed**
A: Yes, as long as the existing roof sealant is asphalt based.

**Q: Can you apply it with a paint spray gun**
A: Yes you can apply our Liquid Rubber Metalsafe Sealant with a heavy duty, airless paint sprayer. If needed the product can be thinned with 5% distilled water by volume. Liquid Rubber USA/CAN has great technical support, application info and videos.

**Q: Can this be used as a bedliner? i have a mid-size truck. plaaning on using entire gallon. this hold up to solvents, texas sun, heavy stuff sliding?**
A: Hi, the Liquid Rubber MetaSafe is not meant as a bedliner.   You may want to look at a Polyurea type Coating.  Liquid Rubber USA has great technical support, application info and videos.
