About DR.FIXIT FEVISEAL HY-100 HYBRID SEALANT LM GREY (600ML)

 91 000 74051 Feviseal HY-100 is a one-component, moisture-curing, low-modulus hybrid sealant (silyl-modified polymer) engineered to combine the benefits of polyurethane & silicone sealants. It offers excellent elasticity, adhesion, durability, and resistance to UV, weather, and aggressive atmospheres. It cures without sagging and is solvent / isocyanate-free. 

Key Features & Benefits
Single-component, moisture-curing; no mixing required. 

Low modulus (flexible) accommodates joint movement (25 %) and elongation up to ~400 %. 

Good adhesion to multiple substrates: concrete, metal, brick, marble, tiles, etc. Primer-less adhesion in many cases. 

Damp surface tolerant; non-sag paste (stays in place on vertical joints) 

Resistant to UV, weather, chemicals. Low dirt pickup. Non-staining.

Q1. What joints is HY-100 suitable for?

It is suited for expansion, construction, control joints, and materials that move due to temperature or structural shifts. It also works between different building materials.

Q2. Is primer needed?

In most cases no primer is necessary. But for continuously wet or highly porous surfaces, using a primer (or Pidiprime A) may improve adhesion. 

Q3. Can it be used on damp surfaces?

Yes, it is damp surface tolerant. However, too much water (ponding) may affect curing. 

Q4. What is the joint depth vs width ratio?

For joints of 6-12 mm width, the depth should be 1:1. For wider joints (12-25 mm), depth half the width (2:1 ratio to width). 

Q5. What temperature range is good for application?

Recommended application range is roughly 5 C to 40 C. Storage and pre-conditioning may help at cold temps. 

Q6. What surfaces should it not be used on?

Natural stone joints that may stain. 

Constantly chlorinated water immersion (pools, spa) or salt water immersion. 

Bituminous surfaces, some plastics like PP, PE, Teflon etc. 

Q7. What is the approximate price?

Listed at 410 for 600 ml pack at certain dealers. Price may vary with region and seller.
