Fosroc Nitoseal MS300 is a one part, high modulus, damp tolerant, floor and pavement joint sealant based on hybrid silyl modified polyether technology.
Suitable for use for sealing saw-cut and movement joints in internal floors, and external joints where abrasion resistance is required. It can also be used for external facade joints where a tougher seal is required.
Fosroc Nitoseal MS300 has a rapid rate of cure and forms a tough elastomer capable of supporting heavy wheel loads.

Application Notes

Limitations
- Do not apply at temperatures below 5°C
- Not suitable for contact with bituminous materials
- Whilst Nitoseal MS 300 has excellent adhesion to many types of residual sealant its use should not be considered a substitute for a good standard of joint preparation
- In large joints ensure sealant is sufficiently cured before trafficking. In 40mm joints this could be up to 10 days
- Flush finished joints should not be used in locations where significant thermal movement may occur during service (e.g. external locations, particularly areas subject to direct sunlight) as this can result in the sealant bulging above the joint surface when the joints contract

Questions
Question about the product
 Ian Hince on 2024-04-09 07:37:42 | Question: Can you paint over Fosroc 300 (with an epoxy paint)? Thanks. |
Answer from Rawlins’ Technical Team: Yes, but this product is a flexible sealant, designed to move with joint movement, which would therefore mean any paint applied that isn't flexible would crack and fail with any such movement. | |
| ian clayton on 2023-02-10 13:58:49 | Question: do i need a primer with nitroseal ms300 |
Answer from Rawlins’ Technical Team: Fosroc Primer MS2 is required for joints that are to be intermittently or permanently immersed, or where the substrate is likely to be saturated (for example, externally) Nitoseal MS300 should be applied between 30 minutes and 4 hours after priming. | |
